ABSTRACT
Reverse e-logistics has proven to have high significance in terms of profits, customer satisfaction, competition, and performance’s efficiency. However, several firms in the Business-to-Consumer (B2C) e-commerce field, especially in developing countries such as those in the Middle East, still neglect its importance for the survival of the firm because they don’t know how to improve reverse e-logistics (REL) performance. Therefore, the objective of this article is to identify the main factors that impact reverse e-logistics’ performance and to analyze their effect. The methods used in this article are: scientific literature review, synthesis, questionnaires, and structural equation modelling. The study is done in Lebanon and Syria with a sample of 459 companies in the electronic industry who are engaged in B2C e-commerce and is faced with reverse e-logistics’ challenges. The estimated results prove the significant impact of the identified factors: customer satisfaction, guarantee, and organization structure on reverse e-logistics’ performance, which in turn has a significant impact on the efficiency of the performance of B2C companies engaged in reverse e-logistics activities as well.

INTRODUCTION
Overall, the value of
the global e-logistics market was USD 4 trillion in 2013, or about 10 percent
of global GDP (WU et al., 2017). Among the top regions that are growing
tremendously in B2C e-commerce, is the Asia-Pacific area, including the Middle
East, which recorded an increase of 23% in B2C e-commerce utilization in 2014
(XU et al., 2016). Thus, creating opportunities for established and existing
firms to consider this area more and to invest in it. In 2016, there were more
than 2.5 billion B2C e-commerce consumers in the world, yielding on average 2671
billion USD, among which is 1057 billion USD contributed Asia-Pacific region
and the Middle East, giving it a top position among other regions (CHOI; MAI,
2018).
In 2013, reverse
e-logistics’ costs accounted for a range between 800 million to $1 billion, and
these numbers are expected to grow tremendously (MAHINDROO et al., 2018). In
2015, the costs of reverse e-logistics’ were about 130.6 billion USD and 223.6
billion USD for Asia-pacific and EMEA regions, respectively. Moreover, the
returned products’ costs for retailers recorded was about $260 billion for the
same year (MORGAN et al., 2018). Returned products represent more than 35% of
the total e-commerce retailers’ cost (HUANG et al., 2015).
The good news is that
when REL is implemented correctly, will lead to better resources’ efficiency,
and thus lower costs and higher profits (GAMBOA; RIVEROS, 2019). Statistics had
shown that reducing costs form REL operations alone, account for at least 10%
improvement in profits for an organization (SANGWAN, 2017). Moreover, the
effective implementation of REL will lead to higher customer satisfaction
(PANIGRAHI et al., 2018). The problem is preventing REL from happening is
almost impossible. Moreover, measuring and improving performance of REL is
highly complicated and difficult (EUCHI et al., 2019).
Despite the fact that
some firms have already implemented effective measures to improve REL
performance, yet there are numerous firms, especially in the Middle East, that
weren’t able to enhance REL activities because they don’t know how. Limited
knowledge exist about specific factors affecting REL performance, and whether
focusing on such factors will enhance REL performance. There is scarcity in
scientific researches in the field of REL’s performance measurement, globally
and precisely in the Middle East, where most firms still struggle in the
logistics’ field.
Thus, this study is
conducted in Lebanon, and Syria. It involves 459 companies in the electronic
industry that perform reverse e-logistics. The objective of this study is to
determine the most important factors that impact REL performance of reverse
e-logistics and to see whether enhancements in such factors will in turn lead
in enhancement in REL performance, and thus better companies’ performance.
Thereby, the following
research question (RQ) is imposed: What are the factors that affect the
performance of reverse e-logistics and to what extent do REL activities affect
the companies’ performance? The methods used in this study are, literature
review, synthesis, comparison analysis, and survey method manifested by online
questionnaires, using google forms that were sent to the electronic companies
in the REL field and the structural equation modelling (SEM) was used to
analyze the data using Amos software.

REVIEW OF LITERATURE
The Development of ICT
generated new possibilities for organizations management, and is becoming more
and more potent in the economic sector. Therefore, it is vital to understand
its significance as an innovative tool to communicate with consumers (BARROSO
et al., 2019; DAVIDAVIČIENĖ et al., 2017).
Application of ICT in
business created opportunities and advantages, yet on the other hand it created
new challenges for business organizations as well. Exchange of information,
buying and selling products through the internet have become common in today’s
business transactions. Several people joining virtual groups, organizations and
networks for business development reasons, and utilizing such opportunities a
lot (DAVIDAVIČIENĖ et al., 2019; MERKEVIČIUS et al., 2015).
Such progression in ICT
lead to the development of E-commerce business, especially B2C e-commerce, that
in turn lead to expansion of e-logistics. E-logistics is the process of
implementing diverse logistics’ activities from dealing with manufacturers,
distributors, logistics hubs, to dealing with consumers through using the
internet (SKITSKO, 2016). After the huge expansion of e-logistics, some
products ordered online had to be returned for different purposes such as:
reutilize, fix, renovate, recycle, and prefabricate, or either completely
discarded, and this is known as REL or reverse e-logistics (EUCHI et al.,
2019).
Reverse e-logistics is
the process of implementing all diverse activities of reverse logistics (RL)
electronically. In other words, reverse e-logistics is the information and
communication technology (ICT) empowered form of reverse logistics (KHAN et
al., 2012). The latter was created after the progress of internet, information
and computer technology, and the wide utilization of electronic presentation of
information within information logistics (SKITSKO, 2016).
REL is a series of
processes in which different kinds of products, whether defected or wrong or
for the sake of recycling, are assimilated from users to the producer’s
profitability (GAMBOA; RIVEROS, 2019). REL concept goes back to the earliest
90s, where several countries noticed the importance of taking care of the
environment and its natural resources, which in turn will yield profits if
resources were used wisely. REL offered the opportunity to recycle, discard
hazardous or normal products, or reuse them efficiently, and this pulled out
the attention of both manufacturers and researchers (RACHIH et al., 2019).
At that the Council of
Logistics Management (CLM) that stated that REL is the planning, implementing,
and controlling the efficient use of resources/products to get from consumers
to manufacturers in a cost-effective manner (ROGER; TIBBEN-LEMBKE, 1998). REL’s
significance is not related only to increasing profits, but also to better
competing position, efficiency in performance, and customer satisfaction (YOGI,
2015; HUANG et al., 2015; EUCHI et al., 2019; AGRAWAL et al., 2016; GAMBOA;
RIVEROS, 2019; SANGWAN, 2017; MAHINDROO et al., 2018; MORGAN et al., 2018).
REL’s costs are 9.5% of
the supply chain cost (SANGWAN, 2017), sometimes reaching $1 billion (MAHINDROO
et al., 2018). Moreover 35% of e-commerce products are returned for different
reasons (HUANG et al., 2015). Today’s dynamic environment and the fast
technological pace leave no room for REL mistakes because the price will be
big. The problem is that REL can’t be completely prevented, and at the same
time it is full of complications due to its complex working systems (SUDARTO et
al., 2017). Thus fast, efficient, and effective solutions in REL are required
to better meet customers’ needs (EUCHI et al., 2019). Complications of REL
constantly requires the existence of original, creative, efficient and
cost-effective solutions (AL MAJZOUB; DAVIDAVIČIENĖ, 2019).
In today’s e-commerce
business, the success of e-logistics’ can’t be achieved with the effective
implementation of REL systems. That is both forward and backward movements in
the supply chain should be taken into consideration (KAZEMI et al., 2018). In
the previous years, the focus on important aspect to increase companies’
performance such as efficient use of resources, better competition, higher
market share and profits, emphasized a greater attention in the field of REL
interest (BAI; SARKIS, 2019).
2.1.
Reverse
E-Logistics’ Performance Factors Evaluation
The most important
factors that might have a direct impact on REL performance, and which were
emphasized by scholars and experts in the field, will be discussed further.
· Third-party reverse logistics provider (3PRLP): Choosing the optimal 3PRLP in terms
of both costs and effectiveness, is central in the REL processes application.
The sustainability of the supply chain resources’ and REL performance are
highly dependent on the good selection of 3PRLP, which gave it even a more
important role than before (BAI; SARKIS, 2019). Outsourcing REL activities to
3PRLP is favored especially when the firms realize the difficulty of REL
processes, and/or there exists a state of scarcity in resources (LI et al.,
2018). Numerous partners are needed to cooperate competently to attain best REL
performance (TOSARKANI; AMIN, 2018). Thus, reverse logistics’ outsourcing to a
3rd party is increasing tremendously due to its huge importance in that field
(SREMAC et al., 2018). To enhance REL performance, then the attention should be
drawn to the proper implementation of third-party logistics (SANGWAN, 2017).
· Organizational Structure: The impact of organizational structure is high on REL performance
(MORGAN et al., 2018). Organizational structure positively affects REL
performance when it is done correctly. However, if the firm is faced with a bad
structure then it will be considered as a barrier to the efficient performance
of REL. For instance, a firm that doesn’t provide its working staff with continuous
training and education, will have a poor REL performance (SIRISAWAT;
KIATCHAROENPOL, 2016). An organization structure impact’s level on REL
performance depends on its own rules, guidelines, protocols, and cooperation
ambiance between its managers and employees (WAQAS et al., 2018). Sometimes the
performance of REL is affected by the bull-whip effect of stock’s level
consistency if the organization structure used can’t accurately forecast the
order rate and inventory rate (CANNELLA et al., 2016). As a matter of fact,
organizational structure has one of the most potent impact on REL, which in
turn REL has a high dependency on it to achieve better results (YADAV; BARVE,
2015).
· Infrastructure: Infrastructure can be explained in diverse terms. It could be in terms
of the facilities such as storage areas, equipment and transportation
(SIRISAWAT; KIATCHAROENPOL, 2016). It also extend to include electricity,
roads, maintenance, industry, forecasting planning, and systems to control
returned products (PRAKASH; BARUA, 2015). Firms that have problems in their
infrastructure means that they have problems in managing returned or recalled
goods, thus a problem in REL (SIRISAWAT; KIATCHAROENPOL, 2016). Thus if a firm
has good infrastructure, then it should be able to manage returned products
efficiently. However, its absence will impact company’s capability to manage
these returns thus will cause way less profits (PRAKASH; BARUA, 2015).
A company’s
infrastructure is fundamentally connected to its supply chain. The
infrastructure is a part of diverse logistical activities including the REL,
which can’t be completed without the convenient infrastructure (MORGAN et al.,
2018). A bad technology and infrastructure will be considered as a barrier not
only for REL development but to the entire firm as well (GOVINDAN; BOUZON,
2018). REL is driven by infrastructure and technology, which cause enormous
challenge manifested by a deficient logistical system. A common example would
be in the developing countries where transport infrastructure is extremely poor
including bad roads, this resulted in huge truck maintenance expenses and
freight damage (BOUZON et al., 2015). Thus, a convenient infrastructure that
takes into consideration resources’ efficiency must be selected if a firm
wishes to have an efficient REL system (YOGI, 2015). Therefore, an effective
REL systems can’t be reached without a proper firm’s infrastructure (CHINDA,
2017).
· Guarantee:
There exist several reasons for customers to return goods, among them is
warranty which in turn plays a significant impact on REL (PANDIAN; ABDUL-KADER,
2017). Warranties can result in bigger amounts of repairs and returned goods,
thus affecting REL processes (HUANG et al., 2015). However, not granting a good
guarantee to customers will cause problems as well since they will not be
reassured to buy the product in the first place (EUCHI, et al., 2019). Numerous
businesses started integrating the reverse e-logistics strategies with their
companies’ strategies and supply chain because a big number of returns is due
to warranty returns (YOGI, 2015). Firms manage REL differently especially when
it comes to warranty of products since it continuously impacts their sales
(PANIGRAHI et al., 2018).
· Inventory management: Companies that are not willing to outsource, have to deal strategically
with inventory management since this in turn will impact REL performance as
well (VLACHOS, 2016). An organized, efficient, and well-controlled REL can in
turn yield huge savings in terms of costs, and better inventory management as
well (AGRAWAL et al., 2016).
Forecasting
methods aid in determining and in preparing the approximate amounts of
inventory level and when done correctly can yield an acceptable inventory
turnover rate, yet uncertainty seems always to exist. In the presence of REL,
good inventory management will improve its efficiency (YOGI, 2015). It was
proved that management awareness of the importance of having a good inventory
control is an indispensable part to enhance capabilities of REL (PANIGRAHI et
al., 2018). Several studies showed that the higher the return products are, the
lower is the bullwhip effect. However, other studies proved that the stability
of inventory management is enhanced when the amount of recollected goods
increase as well (CANNELLA et al., 2016).
· Customer Service. In order to obtain a good customer service, firms must know as
indicated before the expenses of its inventory in order not to fall in the
shortage or surplus trap (YOGI, 2015). The concentration on a better REL
systems, initiated in turn the concentration on having a good customer service
since the latter will yield in more sales thus enhancing the whole supply chain
(LINTON et al., 2007). Customer service is the delivery of goods to customers
in a way that differentiates the firm’s values using good logistics’
management, and which result in customer satisfaction and logistics management.
Customer service is now even way more than before impacting REL and the entire
organizations, due to its significant relevancy to customer satisfaction
(COOPER et al., 2016).
The most
captivating feature of excellent customer service is that every customer
demands different remarkable service. This explains the importance of the entire
supply chain in doing so, including REL that must cooperate to ensure the
customer's needs are met (OCHOCKA, 2019). Customer service is the minimum
service that a customer expects to obtain during any purchase. Thus, in case of
returning a product through REL, he/she expects to see a good service as well
(ASIAN et al., 2019). Despite the fact that several firms utilize the diverse
social media platforms for e-commerce, yet they overlook that importance of a
good customer service that if disappears will lead to returning products and
thus increase REL (DAUGHERTY et al., 2019).
2.2.
Performance
Measurement of REL
Performance measurement
is very crucial for a firm aiming to reaching its goals, and putting better
competitive strategies (YOGI, 2015). Only few authors discussed how REL
performance measurement can be done due to its complexity (SHAIK; ABDUL-KADER,
2018; YOGI, 2015; AGRAWAL et al., 2016; PANDIAN; ABDUL-KADER, 2017). Perhaps,
the best way to measure performance of REL is measuring four important points:
RL cycle time, network capacity, transportation capacity, and recovery
efficiency rate (YOGI, 2015). From another perspective, taking into
consideration the economic and profit programs, technology, corporate social
responsibility programs can be used as well to measure REL performance (DA
SILVEIRA GUIMARÃES; SALOMON, 2015).
In every firm, the need
of certain competencies are required to measure REL performance. Criteria such
as the financial, environmental, innovation, meeting diverse stake holder
needs, and social criteria are usually potent indicators used in the
measurement process (SHAIK; ABDUL-KADER, 2018). Triple bottom approach is a
very popular one in measuring REL performance. It relies on taking into
consideration three aspects the economic, environmental, and social performance
in addition to their relative sub- criteria that help in further analysis
(AGRAWAL et al., 2016).
Performance measurement
can also be done in terms of lead time, input and output quantities, and
stimulating agents. These agents represented are mainly the gatherer, provider,
supplier, reproducer, and recycler agents (PANDIAN; ABDUL-KADER, 2017). The
complexity of REL performance measurement necessitates taking into
consideration indicators that facilitate this process. Indicators such as a
good green and environmental image, flexibility in recycling or fixing defected
products, good quality products, responsiveness rates, costs, and revenues all
can be used to measure REL performance (SIRISAWAT; KIATCHAROENPOL, 2016).
Over the past few
years, the most frequently criteria utilized in the performance process of REL
are: information and communication, management, technology, and social
commerce. For the social commerce in prospect, it has four important
sub-criteria the: reviews, quality control, customer relationship management,
and utilization risk (HAN; TRIMI, 2018). However, two very important aspects
that are often neglected in REL measurement performance are the commitment to
efficiency when using resources, and the frequency of returned goods (MAHINDROO
et al., 2018).
Performance measurement
of REL is the way of estimating the efficiency of the total activities related
to REL. Efficiency here refers to meeting the customers’ needs at the lowest
cost possible, however at the same time reaching customer satisfaction (EUCHI
et al., 2019). Firms seeking opportunities for a better market position should
strive to excel in measuring performance in terms of environmental, economic,
and controlling (HUANG et al., 2015).
Evaluating and
measuring the degree of a firm’s enhancement on important REL outcomes such
technology implementation, distribution period, inventory quantities, and
maximum capacity usage, all will lead to a sustainable REL and thus a
sustainable supply chain (MORGAN et al., 2018). Brief, REL performance
enhancement can’t be reached without enhancing environmental, economic, and
social aspects, since they are positively related to REL performance (BAL;
SATOGLU, 2018; SUDARTO et al., 2017).
2.3.
Performance
Measurement of companies’ efficiency
Evaluating companies’
performance is heavily impacted by the REL performance. Several authors
explained how a firm can measure its performance. One famous method to measure
companies’ efficiency is the balanced scorecard (BSC), by which the firms can
indicate the overall performance and where improvement can be made (SHAIK; ABDUL-KADER,
2018). Commitment to resources’ efficiency is a key indicator for a good
performance (YOGI, 2015).
Despite the fact that
the efficient use of resources’ is used in REL performance measurement,
nonetheless it is used for companies’ performance as well (MAHINDROO et al.,
2018). Resources’ efficiency mixed with a low cost is sometimes sufficient for
an effective performance measurement (EUCHI et al., 2019). Efforts to enhance
firms’ performance alone might negatively affect the entire supply chain thus
leading to catastrophic results.
Performance’s
measurement can be done through measuring of financial and marketing results.
As a matter of fact, for an efficient measurement of companies’ performance, a
company should take into consideration not only the financial capital, but the
physical capital, and operational capacity as well (JIANU et al., 2017). In
order to do a proper assessment of companies' performance related to reverse
e-logistics, a firm should definitely consider performance characteristics such
as product lifecycle, market strategies, procedures, and firm’s production and
monitoring capabilities (WANG et al., 2019).
Effective companies’
performance management should not be done without a good supply chain
management measurement, which can be done in terms of cost saving and
operational efficiency (YADAV; BARVE, 2015). Forming of Omni-channels can be
effective as well. These channels include assessment of assimilation of
procedure, information stream, and inventory turn-over rate (ANG; TAN, 2018).
Performing the capacity planning in both an efficient and flexible manners is a
potent indicator for companies’ performance (SUDARTO et al., 2017).
Indicators such as a
firm’s financial performance, market competition, use of technology, and employment
satisfaction, are used by logistic firms to measure their competencies in the
market field of their domain (CHINDA, 2017). Considering financial and lowering
costs indicator for efficient companies’ performance is important, however
neglecting the stakeholder’s satisfaction might hurt a company’s performance
(GOVINDAN; BOUZON, 2018). Actually, REL itself contributes to the firm’s
performance financially. Thus, taking care of REL means taking care of firm’s
performance as well since they are directly linked (LARSEN et al., 2018).
A beneficial way in
measuring performance would be the use of key performance indicators for the
various cost incurred over a specific period of time. For instance, measuring
before and after effect of implementing efficient REL in terms of collection
costs and energy savings (SANGWAN, 2017). From another perspective, evaluation
performance should be done as a triple way framework: the strategic, tactical
and operational into a cost-benefit analysis manner (PANDIAN; ABDUL-KADER,
2017).
Focusing on reduction
of consumption of resources varying from decreasing energy consumption to less
utilization of resources, is an indispensable part of an efficient firm’s
performance (WANG et al., 2018). Nonetheless, operational performances’ cost
should also be included in that evaluation processes (MORGAN et al., 2018). The
first thing a firm needs to is to identify the diverse scales of finance,
stakeholders, procedures both in-house and out-house, and novelty to be used as
a competitive edge (BOUZON et al., 2015).
Standards in quality of
goods or services quality, in addition to costs’ measurement, are good
indicators to measure a firm’s performance (LI et al., 2018). Other firms rely
heavily on using the Net Present Value (NPV) as a sole indicator to measure the
economic performance of a firm, and for them this is the most important factor
that should be studied and monitored (BOGATAJ; GRUBBSTRÖM, 2013).

METHODOLOGY
As stated earlier, the
aim of this research is to identify the most potent factors affecting REL
performance, and the effect of REL activities on the companies’ performance.
Therefore, the research question that was imposed earlier is that: What are the
factors that affect the performance of reverse e-logistics and to what extent
do REL activities affect the companies’ performance. Thus, after identifying
the most potent six factors that might be affecting REL performance, the next
step is to validate the following hypotheses that were formulated based on the
analysis made from the literature review part, and from the imposed research
question.
After determining the
factors that might be affecting reverse e-logistics, the next step is to verify
these factors by first developing the following hypotheses:
· H1: Customer satisfaction positively
correlated to REL performance
· H2: Inventory management is
positively correlated to REL performance
· H3: Bad infrastructure is negatively
correlated to REL performance
· H4: Organization structure is
positively correlated to REL performance
· H5: Guarantee is positively
correlated to REL performance
· H6: Ineffective third party is
negatively correlated to REL performance
· H7: REL performance is positively
correlated to the efficiency of company’s performance.
· H7-a: REL performance is positively
correlated with the company’s profits
· H7-b: REL performance is positively
correlated with resources’ efficiency
· H7-c: REL performance is positively
correlated with operational capacity
Thus, the next step is
to validate by accepting or rejecting the above hypotheses, by using
questionnaires and SEM through Amos software.
Concerning the
questionnaire, it was a five-point Likert scale one that was sent to 682
e-commerce companies in Lebanon and Syria and that perform e-commerce and
consequently reverse e-logistics. The questionnaire is made up of a total of 35
questions, out of which 10 are demographics and 25 asking about reverse
e-logistics’ performance in the company.
A total of 561 were returned, and after excluding the ones that do not
perform reverse e-logistics answers, the total was 459 answers (67.30%
response). A five-point Likert scale was used (1=strongly disagree, 2=disagree,
3=neutral, 4=agree, 5=strongly agree) to do the analysis.
As a validation to the questionnaire,
Cronbach’s alpha value was applied. Concerning Cronbach’s alpha value, it
ranges from 0 to 1; the higher values propose greater internal reliability.
The, alpha value from 0.70 and above indicates reliability. This is the case in
all of the above variables except for employees, but it is still in the
acceptable range. This means that the results for the latent variables under
study are reliable. The recorded alpha values are summarized in Table 1 below.
Table 1: Cronbach’s alpha of latent variables

Concerning the validity of sample size adequacy of data that were used in factor analysis, two tests were used for that purpose: the Kaiser-Meyer-Olkin (KMO) and Bartlett’s. These tests were used because they are the most popular tests used for measuring adequacy of sampling size and data. KMO implies significance if it is more than 0.5 and here KMO= 0.721, whereas the Bartlett’s test value significance must be less than 0.5 and here Bartlett’s test= 0.000, which again gives reliability to the factors under study. This shows that the compulsory adequacy level is met.
Using AMOS software, we
were able to build the model to test our theories. The model is depicted in
Figure 1 below. Based on the analysis data generated from AMOS, the estimates
calculated and their relative significances are summarized in table
Figure 1: The empirical data model
Using AMOS software, we
need to test the model fit. Table 2 below illustrates the important indicators
that explains if there is a model fit or not.

· CMIN: refers
to the chi-square for the model is also called the discrepancy function,
usually CMIN should be divided by DF (degree of freedom) to analyze model fit.
The CMIN/DF should be between 1 and 3, and here it is 1.338, which indicates
first model fit.
· CFI: refers
to the comparative fit index, compares the fit of our model to that of the
independent variables. This fit contributes to the difference among the
observed and predicted covariance matrices. CFI should be greater than 0.950
for a good model fit, and here it is the case where CFI= 0.975.
· GFI: refers
to the goodness-of-fit index, which is a measure of fit between the hypothesized
model and the observed covariance matrix. GFI should be greater than 0.90 to
indicate the existence of model fit, in our study GFI=0.955, which indicates a
good model fit.
· RMSEA: The
root mean square error of approximation, is used as a mechanism for adjusting
for sample size where chi-square statistics are used. It is implemented as a
supplement to the chi-square fit tests. RMSEA should be less than 0.06, and
here this is the case since RMSEA= 0.027.
· SRMR:
Standardized Root Mean Square Residual; first it indicates if there is any
missing values in the data. , and second it indicates the square root of the
discrepancy between the sample covariance matrix and the model covariance
matrix. SRMR should be less than 0.08, in our study SRMR= 0.042 which is less
than 0.08.
· Pclose: a p
value for examining the null hypothesis that the sample where RMSEA is no
greater than 0.05. It gives an idea about the test of close fit, while P value
gives an idea about the test of exact fit. Pclose should be greater than 0.05
to indicate a good measure fit index, and it’s the case here since Pclose=
1.000.
All of the above
indicators prove that the empirical data fit with the model, thus our model is
fit and can be used to test our hypotheses. Thus, the model fitness indicates
that the results that will be shown later will be considered as valid, since
the absence of model fitness will give the results and values no importance at
all, even if P value was below 0.05. Therefore, the managerial approach that
will be taken will be considered as effective due to this model fitness.

DISCUSSION OF RESULTS
After making sure that
the model fits, now the estimates of the factors affecting REL should be
calculated and analyzed. The estimates which are summarized in table 3 and
table 4, give us an idea about the correlation between the variables understudy
with REL performance.

An estimate between 0
and 0.3 is considered weak positive correlation, between 0.3 and 0.6 is
moderate positive, and 0.6 and 1 indicates a strong positive correlation. Thus,
customer satisfaction, guarantee, and inventory management, have a weak
positive correlation with REL performance. Moreover, Organization structure has
a strong positive correlation with REL performance. For all those factors who
have a positive correlation, this means that if a firm improve these factors,
they will result in an improvement in REL performance. Concerning the other two
factors, Bad infrastructure, and ineffective third party, they have a weak
negative correlation. This means that these factors will result in bad REL
performance.

Concerning the impact
of REL performance on the efficiency of companies’ performance: profits,
resources’ efficiency, and operational capacity, all have moderate positive
correlation with increasing companies’ performance. This means that if REL
performance of a company is improved, it will result in better performance of
the company as a whole.
Based on the above
information, now we can see if our first 6 hypotheses are accepted or rejected.
First, Hypothesis 1,
Customer satisfaction positively correlated to REL performance (estimate=
0.038, p<0.05), is accepted. It means that if the firm is able to maintain
high customer satisfaction, then the REL performance will improve.
Hypothesis 2, inventory
management is positively correlated to REL performance (estimate=0.58,
p>0.05), is rejected. This means that if a firm has good management of its
own inventory, then the REL performance will increase. However, since the P
value is greater than 0.05, this hypothesis can’t be supported.
Hypothesis 3, bad infrastructure
is negatively correlated to REL performance (estimate= -0.108, p<0.05), is
accepted. This means that if a firm has a bad infrastructure, it will not be
able to improve its REL performance.
Hypothesis 4,
organization structure is positively correlated to REL performance
(estimate=0.624, p<0.05), is accepted. This means that the organization
structure can directly affect REL performance, so the firm should be working in
the optimal structure if it wishes to improve its REL performance.
Hypothesis 5, guarantee
is positively correlated to REL performance (estimate=0.123, p<0.05), is
accepted. This indicates that when a firm grants its customers a good
guarantee, then they will be more reassured to buy from them, which in turn
will lead to improved REL performance.
Hypothesis 6,
ineffective third party is negatively correlated to REL performance (estimate=
-0.78, p>0.05), is rejected. It means that when a firm deals with bad
partners in providing third party reverse logistics, the REL performance will
be deteriorated. However, due to the p value that is large than 0.05, it can’t
be indicated as significant conclusion.
Concerning the second
part of our study, which is summarized in Hypothesis 7, it states that REL
performance is positively correlated with companies’ performance efficiency
(estimate= 0.397, p<0.05), is accepted. This hypothesis is divided into
three consequent hypotheses.
Hypothesis 7-a: REL
performance is positively correlated with the company’s profits (estimate=
0.490, p<0.05), is accepted. This means that REL performance, when improved,
can increase the company’s profits.
Hypothesis 7-b: REL
performance is positively correlated with resources’ efficiency (estimate=
0.521, p<0.05), is accepted. This means that good REL performance will
result in an efficient use of resources, that is to say improved REL
performance will increase the resources’ efficiency and thus firm’s resources
will be less used, and this again will yield increased profits.
Finally, Hypothesis
7-c: REL performance is positively correlated with operational capacity
(estimate= 0.479, p<0.05), is accepted. This indicates that improved REL
performance will result in improved operational capacity.
The whole hypothesis
and their relative analysis are summarized in Table 5 below.

Thus, by focusing on
the accepted hypotheses, firms doing B2C e-commerce companies that are facing
REL challenges, should take all of the customer satisfaction, infrastructure,
organization structure, and guarantee factors into consideration if they wish to
enhance REL performance. From the other side, improved REL performance will
result in improved profits, resources’ efficiency, and operational capacity.
A head to head to
comparison between Lebanese and Syrian companies showed that these two
countries share a lot of similarities in term of factors affecting their REL
performance. For instance the factors: customer satisfaction, infrastructure,
organization structure, and guarantee have proven to impact REL activities for
both countries. This could be as a result of similar consumers’ behaviors due
to very close cultures among them.
However, certain
differences exists between the two countries, such as the kind of items
purchased in the electronics industry. For example, the most ordered products
in Lebanon were mainly mobile phones, and sports equipment such as treadmills,
whereas in Syria the most ordered products were laptops and tablets.
5.
CONCLUSION
In today’s
technological advancement, B2C e-commerce is progressing very fast and number
of companies engaging in such transactions is increasing tremendously. However
B2C e-commerce faces many challenges, and perhaps the most important and
complicated one is the reverse e-logistics’ ones, which is often neglected. The
good news is that due to its huge importance, reverse e-logistics is an
indispensable part of a company’s supply chain that can result in huge benefits
to the company such as increased profits, and better competing position.
In the first part of
our study we determined the most important factors that impact REL performance.
A sum of four factors were concluded that are significantly and positively
correlated with REL performance. These factors are: customer satisfaction,
organization structure, infrastructure and guarantee. Thus for a firm wishing
to enhance the REL performance, it should take these factors into consideration
and work on enhancing them, since they will result in an improved REL
performance.
The second part of our
study, we tested the impact of REL on the efficiency of companies’ performance.
We found that there was a significant and positive correlation between improved
REL performance and efficiency of company’s performance. These enhancements in
the company’s performance were enhancements in terms of profits, efficiency of
resources’ used, and better operational capacity as well. This concludes that
if a firm increases the REL performance, it will result in benefits to the entire
company and not only enhancements through its supply chain.
Research limitations
faced in Syria, was the difficulty in communicating highly with the firms
operating there due to the war that is currently occurring in the country. In
Lebanon, the infrastructure still lacks a lot of development to encourage B2C
e-commerce, especially the problems in the internet connection that has a
relatively very slow speed compared to other countries in the Middle East.
Moreover, several follow-up emails had to be sent for companies in both
countries to encourage them to fill up the questionnaires. Indeed, a total of
682 questionnaires were sent and the ones returned were only 459, despite
following up with them on a regular basis.
Developing countries,
including the Middle East still lack a lot of academic researches and findings.
Thus, our future research recommendation is to emphasize more the importance of
doing such researches not only in Lebanon and Syria, but also in the Middle
East where there is a lack of scientific findings in the field of reverse
e-logistics. These countries should be considered as opportunities for B2C
e-commerce business since there is a huge chance to occupy this market and
increase profits for firms operating in B2C field. Finally, the factors
mentioned above are not exhaustive, thus other factors mentioned in our
previous studies and by other scientific scholars should be also considered in
future research for testing.
