ACCEPTED MANUSCRIPT How Service Recovery Affects Liner Shipping Customer Loyalty Abstract
RI PT
Offering appropriate service recovery is important for service providers to retain their existing customers. Given that service failures are both common and inevitable when using liner shipping services, in this study, a model was established by which to examine the impact of service recovery on customer loyalty. An empirical questionnaire survey was conducted, and structural equation modeling (SEM) was applied to test the hypotheses proposed in this study. The results showed there to be a
SC
significant positive impact from service recovery on the customer loyalty of liner shipping users, which was found to be mediated via customer satisfaction and satisfaction after recovery.

1. Introduction
TE D
Liner shipping has been playing an important role in the global cargo transportation industry for more than fifty years (Heaver, 2002). Specially-designed
EP
containers enable convenient cargo transshipment between trucks, ships, and even trains. This so-called door to door service has become more popular because containers can easily be trucked to and from customer premises. Moreover, efficient transshipment also has become the predominant method by which liner shipping
AC C
companies (LSCs) enlarge their sailing networks, which has in turn formed a complete, efficient global transportation infrastructure. In 2016, world container traffic was estimated to have reached 140 million TEUs (UNCTAD, 2017). It’s worth noting that it’s very costly to maintain such a huge transportation system. LSCs have to deploy a large number of ships to sail between ports and must also provide empty containers for shippers to load cargo in. In addition, even when a ship is not fully loaded, it has to depart on time according to the announced schedule. This so-called perishability of service increases the pressure on LSCs to strengthen the loyalty of their customers, most of whom are frequent users of liner shipping services and include manufacturers, trading companies, department stores, wholesalers, logistics companies, freight forwarders, etc. This is why LSCs are happy to sign service contracts with customers that are intended to maintain long-term relationships and stable cargo volumes for each voyage. Several prior studies (e.g. Chao and Chen, 1
ACCEPTED MANUSCRIPT 2015) investigated the determinants of customer loyalty for LSCs and found that service quality and satisfaction have a positive impact on customer loyalty. However, to the authors’ knowledge, issues related to service failure and recovery for LSCs have not as yet been discussed. The aim of this study is twofold. First, the main types of service failure experienced by liner shipping users were investigated and analyzed by conducting an empirical questionnaire survey. Second, a research model was
RI PT
established and validated using structural equation modeling (SEM) to examine the impact of service recovery on customer loyalty in an LSC context. To our knowledge, this study is the first to include service quality, customer satisfaction, and satisfaction after recovery as three mediating variables to investigate the impact of service

SC
recovery on customer loyalty. The remainder of this paper is organized as follows: Section two reviews literature focusing on service recovery and customer loyalty, which were the two core constructs used to establish our research model. The methodology used in this study is described in Section three. Section four presents the results of a study based on an empirical questionnaire survey. The conclusions and implications for future research are summarized in the last section. 2. Theoretical background and hypotheses
TE D
In this section, we first explain the idea that led to the development of our research model. Afterwards, the hypotheses are established based on the related theoretical background. 2.1 Research model development
EP
The aim of this study is to examine the impact of service recovery on customer loyalty in an LSC context. Accordingly, service recovery and customer loyalty were included in our model as two core constructs. Given that these two constructs have
AC C
been investigated in a number of prior studies, it was necessary to comprehensively review studies related to these two constructs before building our research model. According to our review, four frameworks have been commonly applied to investigate the impact of service recovery on customer loyalty. The first directly examines the relationship between service recovery and customer loyalty. This framework has only been used in a few studies (e.g. Chou, 2015) because it didn’t take into account other factors that might simultaneously influence customer loyalty. In terms of the antecedents of customer loyalty, customer satisfaction has been included in a large number of studies across various fields due to its significant impact on customer loyalty. Therefore, the second framework was applied in a few studies (e.g. Kim, 2007; Cheng and Mansori, 2017) by including customer satisfaction as a mediating variable between service recovery and customer loyalty. Because customer satisfaction might be influenced by other factors other than service recovery, some studies further 2
ACCEPTED MANUSCRIPT developed a third framework by including a construct called satisfaction after recovery (e.g. Del Río-Lanza et al., 2009; Kim et al., 2012; Kuo and Wu, 2012; Chang and Chang, 2010) in their models. Because satisfaction after recovery can exclusively measure the impact of specific recovery actions implemented by service providers, we also separated customer satisfaction into customer satisfaction and satisfaction after recovery when designing our model. It’s worth mentioning that an important construct,
RI PT
service quality, has been included in a number of studies related to customer satisfaction (e.g. Yuen and Thai, 2015; Chao and Chen, 2015) and customer loyalty (e.g. Chao and Chen, 2015; Fu et al., 2018). The comprehensiveness of a model measuring the impact of service recovery on loyalty can be increased if service
M AN U
SC
quality is included. This idea, which is the fourth framework, can be found in Kuo et al. (2013). They included service recovery as a moderating variable while examining the effect of service quality on loyalty. Based on the above discussion, we first set up two core constructs, service recovery and customer loyalty, in our model. Afterwards, customer satisfaction and satisfaction after recovery were included as two mediating constructs between the two core constructs. Lastly, service quality was inserted between service recovery and
TE D
customer satisfaction as the third mediating variable. In total, there are five constructs in our proposed research model (see Fig. 1). The hypotheses that validate the impact between the constructs and the indirect impact of service recovery on customer loyalty are established in Section 2.2. < Insert Figure 1 about here >
EP
2.2 Hypotheses establishment
AC C
Based on the constructs developed in Section 2.1, the hypotheses are established in this subsection in two phases. In the first phase, the direct impacts between constructs are hypothesized. After that, the second phase hypothesizes the indirect impacts from service recovery on customer loyalty. (1) Direct impacts between constructs Parasuraman et al. (1988) suggested that service quality is highly correlated with customer satisfaction. Antony et al. (2004) conducted a survey on the relationship between service quality and satisfaction in British hotels and found that service quality is one of key factors related to customer satisfaction. Shanka (2012) measured the service quality of the Ethiopian banking sector and found a positive correlation between service quality and customer satisfaction. When a customer is using a liner shipping service, if an LSC can deliver containers to the right destination on time 3
ACCEPTED MANUSCRIPT without damage, has a frequent schedule, offers a convenient place to receive and deliver containers, delivers documents accurately, and handles customer problems promptly, customer satisfaction may be increased. Accordingly, we propose the following hypothesis: H1: There is a positive relationship between service quality and customer satisfaction
RI PT
with LSCs.
Ganiyu et al. (2012) investigated whether customer satisfaction can be an indicator of customer loyalty. The results of their study supported the premise that
SC
customer satisfaction has a strong positive relationship with customer loyalty. Mohsan et al. (2011) conducted a survey on 120 clients of banks in Pakistan in an attempt to identify the impact of customer satisfaction on customer loyalty. The results showed customer satisfaction and customer loyalty to be positively correlated. Deng et al.
M AN U
(2010) examined the determinants of customer satisfaction and loyalty taking instant phone messages as an example. The result proved that customer satisfaction and customer loyalty are positively correlated. In the case of an LSC, a customer with a high degree of satisfaction may support the LSC continuously or even recommend it to others. Accordingly, the following hypothesis is proposed:
TE D
H2: There is a positive relationship between customer satisfaction and customer loyalty toward LSCs.
Ellyawati et al. (2012) investigated service recovery according to three dimensions: distributive justice, procedural justice, and interactional justice. The
AC C
EP
positive impacts from these three dimensions on customer satisfaction after recovery were all proven to be significant using a survey of retail stores. Suprapto and Hashym (2010) found a positive relationship between recovery strategies and customer satisfaction after recovery by conducting an empirical survey in the hotel industry. By conducting a large-scale survey in Johannesburg, Kruger et al. (2015) found the positive impact of service recovery on satisfaction after service recovery to be significant. Given that most liner shipping customers are frequent users, shipper complaints and negative emotions may be reduced if LSCs can offer effective service recovery after service failures occur. Accordingly, we propose the following hypothesis: H3: There is a positive relationship between service recovery and customer satisfaction after recovery for LSC customers. 4
ACCEPTED MANUSCRIPT By conducting a survey of 1,878 customers of a large Brazilian bank, Matos et al. (2013) found that satisfaction with service recovery was significantly associated with

RI PT
loyalty. Oliver (1997) pointed out that mouth of word and repurchase have a positive relationship with satisfaction after recovery. Given that service failures are inevitable due to weather and other factors, LSCs should try their best to increase satisfaction after service recovery in order to keep their customers. Hence, the following
H4: There is a positive relationship between customer satisfaction after recovery and customer loyalty toward LSC customers.
SC
A number of studies (e.g. Antony et al., 2004 and Shanka, 2012) have been conducted to investigate the impact of service quality on satisfaction, but few of them have discussed the effect of service recovery on service quality when service failures
M AN U
have occurred. Kuo et al. (2013) investigated how service quality affects customer loyalty in the travel agency industry by conducting an empirical survey in Taiwan. The mediating effect of service recovery on the impact of service quality was also examined in the structured model they established. Their results proved that the mediating effect was significant. When using a liner shipping service, the service
TE D
quality perceived by customers may be decreased if an LSC cannot deal effectively with service failures. Accordingly, we propose the following hypothesis: H5: There is a positive relationship between service recovery and service quality for LSC customers.
AC C
EP
Cengiz et al. (2007) empirically studied the banking industry and found that customer satisfaction after recovery has a direct impact on overall satisfaction. Focusing on the airline industry, Chang and Chang (2010) conducted an empirical study to validate the impact of service recovery on satisfaction and customer loyalty. The results showed that customer satisfaction after recovery has a significant influence on customer satisfaction. In the case of an LSC, if recovery after service failure can lead to customer satisfaction after recovery, perceptions of satisfaction with the LSC as a whole may be increased. Accordingly, we propose the following hypothesis: H6: There is a positive relationship between customer satisfaction after recovery and LSC customer satisfaction. Gu and Ye (2010) surveyed the customers of a Chinese online service and found 5
ACCEPTED MANUSCRIPT that service recovery had a significant impact on customer satisfaction. Their results showed that rapid, quality service recovery leads to a greater degree of customer satisfaction. Given that service recovery is a common issue for LSCs, prompt, appropriate service recovery may be helpful for LSCs to increase the degree of satisfaction of their customers. Therefore, we propose the following hypothesis:
RI PT
H7: There is a positive relationship between service recovery and LSC customer satisfaction.
(2) Indirect impacts of service recovery on customer loyalty
SC
In addition to the above hypotheses, which investigate the direct impacts among constructs, we further proposed four hypotheses to identify the indirect impact of service recovery on customer loyalty. Abbas et al. (2015) investigated the impact of
M AN U
service recovery on customer satisfaction and customer loyalty. Based on a review of related literature, they indicated that service recovery might impact customer satisfaction and that the effect would be mediated towards customer loyalty. They suggested that future studies involve empirical surveys to validate these hypotheses. Meanwhile, in the first part of Section 2.2, we proposed seven hypotheses (i.e. H1 to H7 in Fig. 1) describing the impact between the five constructs. In terms of Figure 1 as a whole, the only independent variable is service recovery, the impact of which may
EP
following four paths:
TE D
be mediated by three mediating variables towards customer loyalty. Therefore, based on hypotheses H1 to H7 and the suggestion in Abbas et al. (2015), we hypothesize that the impact from service recovery on customer loyalty will be mediated by the
H8: The positive impact from service recovery will be mediated by customer
AC C
satisfaction towards customer loyalty for LSC customers. H9: The positive impact from service recovery will be mediated by satisfaction after recovery towards customer loyalty for LSC customers.
H10: The positive impact from service recovery will be mediated by service quality and customer satisfaction towards customer loyalty for LSC customers. H11: The positive impact from service recovery will be mediated by satisfaction after recovery and customer satisfaction towards customer loyalty for LSC customers.

ACCEPTED MANUSCRIPT 3. Methodology 3.1 Questionnaire design and construct measures
The questionnaire designed for the purpose of collecting samples in this study comprised two parts. The first part was used to collect the demographic characteristics of the respondents, including gender, age, and work experience. In addition, basic
RI PT
information about the firms for which the respondents were working, i.e. firm history, monthly transportation volume, and number of employees, was also collected. In the second part of the questionnaire, the question items were designed in groups to collected the respondents’ opinions on different constructs. To ensure the content

SC
validity, all constructs and question items were sourced from prior studies (see Table A1 in the Appendix). Additionally, a pilot test was conducted in October 2013, in which two professors and five practitioners in the liner shipping industry were invited to review the draft of the questionnaire. All question items were improved based on their suggestions.
In term of construct measures, unlike physical products in the manufacturing industry, the service offered by LSCs is intangible and as such, is not easily measured. Therefore, the five evaluation dimensions of the SERVQUAL model, which have been applied widely in service-related studies, were used in this study to measure LSC services. To measure service quality, the question items used in this study were
EP
TE D
sourced from Brooks (1990) and Premeaux (2002). These items were categorized in terms of tangibility, reliability, responsiveness, assurance, and empathy, which are the five dimensions in the SERVQUAL model proposed by Parasuraman et al., 1988. The construct for customer satisfaction, which has appeared in many service-related studies, was measured using items sourced from Miller (2000) and Lin (2007). The items for measuring customer loyalty were sourced from Oliver (1999), Gronholdt et
AC C
al. (2000) and Kheiry and Alirezapour (2012). The construct for service recovery was measured using items sourced from Hoffman et al. (1995). The items for measuring satisfaction after recovery in this study were sourced from Tax et al. (1998) and Maxham III and Netemeyer (2002). All constructs in our proposed model were measured with items used commonly in previous similar studies although some minor modifications were made to fit the items to the study context. The question items used in the questionnaire were grouped according to above mentioned constructs to help the respondents understand the logic (Venkatesh and Davis, 2000). All respondent opinions were measured on Likert-type, multiple item scales, ranging from 1 for ‘strongly disagree’ to 5 for ‘strongly agree.’ The measurement items are listed in the Appendix (see Table A1). 3.2 Sampling and data collection 7
ACCEPTED MANUSCRIPT The population of this empirical study comprised the top 500 import and export firms as identified by the Ministry of Economic Affairs in Taiwan. Questionnaires were sent to 500 of these firms who had used liner shipping services from December 2013 to January 2014. A total of 211 out of the 500 questionnaires were returned, of which 17 questionnaires were deemed invalid; hence, the remainder accounted for an effective rate of 38.8%. By analyzing the basic information in the returned samples
RI PT
listed in the Appendix (see Table A2), we found that 48.4% of the respondents had been working for their companies for more than ten years, of which those who had more than 20 years of experience accounted for 11.3%. 76.8% of the companies had been in operation for more than ten years. Most companies were considered frequent

users since 58.5% of them moved more than 100 twenty-foot equivalent units (TEUs) of containers monthly, of which 33.5% moved more than 200 TEU per month. In addition, 46.9% of the companies had more than 500 employees at the time of the study. According to above data, the respondents were experienced and knowledgeable and had worked for a specific period of time, showing that the results of our empirical study were reliable. In this study, we summarized six types of service failure that are commonly experienced while using liner shipping services, including schedule delays,

Anderson and Gerbing (1988) suggested that an SEM analysis can be divided into two steps. The first step is a measurement model that tests the relationship between the observed and latent variables. The second step is a structural model that tests the relationships between constructs. In this study, this two-step concept was used to test the reliability and validity of the collected samples and to validate the proposed hypotheses. < Insert Figure 2 about here >
4. Results 4.1 Measurement model analysis
The results of the reliability test are provided in Table 1. All construct reliabilities in the measurement model were found to be greater than 0.7, exceeding the recommended level of 0.7 (Hair et al, 1998), and the AVE value of each construct exceeded the recommended level of 0.5 (Bagozzi and Yi, 1988), which indicates that 8
ACCEPTED MANUSCRIPT all latent constructs had good reliability. < Insert Table 1 about here > The results of the convergent validity test are also presented in Table 1. All factor loadings of the constructs exceeded 0.5, which ensured the desired convergent
RI PT
validity of our empirical study (Kline, 1998). Accordingly, we confirmed sound convergent validity between the collected data and the measurement model in this study. Table 2 presents the results of the discriminant validity tests. It is obvious that discriminant validity was achieved because all χ 2 differences were significant. A
SC
greater difference indicates less of a relationship between the latent constructs. That is, the latent constructs in this study were deemed representative.
M AN U
< Insert Table 2 about here >
Regarding the goodness-of-fit measures of the measurement model, the normalized χ 2 value was 1.487, which was acceptable because it was less than three. Five other measures, the goodness-of-fit index (GFI) (value of 0.894), adjusted GFI (AGFI) (value of 0.855), the normed fit index (NFI) (value of 0.901), the comparative
TE D
fit index (CFI) (value of 0.965), and the root mean square residual (RMR) (value of 0.019) all achieved their acceptance thresholds (Bagozzi and Yi, 1988; Koufteros, 1999) (see Table 3). Therefore, there was sound fitness between the data and the latent constructs of the measurement model.
EP
< Insert Table 3 about here >
4.2 The structural model analysis
AC C
The structural model analysis was used to test the relationships between the latent constructs. As Table 4 illustrates, six goodness-of-fit indexes were tested, and all fitness indexes between the returned samples and the structural model achieved their acceptance thresholds. Therefore, these measures demonstrated sound fitness between the collected data and the structural model. < Insert Table 4 about here > In this study, the critical ratio (CR) outputted from the AMOS 18 package was used to test the path coefficients between the constructs. A CR value greater than 1.96 or less than -1.96 reflects the significance of the path. According to results shown in Table 5, all hypotheses reflecting direct impacts were significant and supported 9
ACCEPTED MANUSCRIPT statistically except service recovery toward customer satisfaction (H7). The values of the squared multiple correlations (R2) were used in this study to examine the amount of variance of each construct accounted for by other constructs. With a range between zero and one, a high value of R2 shows that the amount of variance of a construct is well accounted for by other constructs. The results of the structural model analysis are shown in Fig. 3. As a whole, the results of structural model analysis reflected that the
< Insert Table 5 about here >
SC
< Insert Figure 3 about here >
RI PT
model had good explanatory power because the R2 value of customer loyalty reached 0.726.
4.3 Research hypotheses test
M AN U
The hypotheses proposed in this study are discussed in this subsection in two phases. The first phase discusses the direct impacts (i.e. H1 to H7) based on the results shown in Table 5. After that, the indirect impacts (i.e. H8 to H11) are tested and analyzed. In terms of the direct impacts, Table 5 lists the results of the statistical tests, in which the path coefficient of service quality on customer satisfaction was
TE D
significant and reached 0.737, meaning that the respondents felt that service quality as provided by an international LSC has a positive impact on customer satisfaction. Therefore, H1 was supported. The path coefficient of customer satisfaction toward customer loyalty was 0.676 and significant, showing that the satisfaction of shippers
AC C
EP
can affect their loyalty. Therefore, H2 was supported. That is, if a shipper is satisfied with services provided by an LSC, the chance that the shipper will switch to other LSCs will be lower. The path coefficient of service recovery toward satisfaction after recovery was as high as 0.909 and was thus statistically significant. Such a high value means that the respondents felt that service recovery can affect satisfaction after recovery for LSCs. Therefore, H3 was supported. That is, if an LSC can offer effective and timely service recovery, the satisfaction after recovery of its customers will be increased. The path coefficient of satisfaction after recovery toward customer loyalty was only 0.227 but was still significant. This means that the respondents felt that satisfaction after recovery can affect customer loyalty to some degree. Therefore, H4 was supported. Because most users of liner shipping services are frequent shippers, this result indicates that if an LSC can increase satisfaction after recovery, then its shippers will be more willing to support it continuously. As for the impact of service recovery on service quality, the significant coefficient of 0.727 indicated a strong positive relationship. Accordingly, H5 was supported. Such a result is notable for LSCs, who should pay attention to offering appropriate service recovery in addition to 10
ACCEPTED MANUSCRIPT focusing on improving the quality of their service. The path coefficient of satisfaction after recovery toward customer satisfaction was 0.272, which exceeded the recommended level, meaning that the respondents felt that satisfaction after recovery can affect customer satisfaction to some degree. Therefore, H6 was supported. Lastly, H7 was not supported because the path coefficient of service recovery toward customer satisfaction was not statistically significant.
RI PT
In terms of the indirect impact of service recovery on customer loyalty, we first tested the mediating effects via customer satisfaction (H8) and via satisfaction after recovery (H9), respectively. Because there was only one mediating variable in these two paths, respectively, their effects could be tested using Sobel tests. The z-value in
M AN U
SC
the Sobel test of the mediating effect via customer satisfaction was only -0.227, which didn’t reach the acceptable threshold (i.e. an interval between -1.96 and 1.96) suggested by Sobel (1982) (see Table 6). Accordingly, H8 was rejected. However, H9 was supported because its z-value in the Sobel test was 2.291, indicating that the effect from service recovery towards customer loyalty via satisfaction after recovery was significant. Finally, the two indirect effects of service recovery on customer loyalty through
TE D
two mediators were tested using the PROCESS 2.16 package. The bootstrapping process was applied to estimate the confidence interval (C.I.) (Shrout and Bolger, 2002). Significance is achieved if the C.I. doesn’t include zero. According to this criterion, the first path in Table 7 was insignificant because its C.I. included zero. Therefore, H10 was not supported, indicating that the effect from service recovery didn’t extend to customer loyalty via this path. However, the second path in Table 7
EP
was significant because its C.I. didn’t include zero. Therefore, H11 was supported, meaning that the respondents felt that the effect of service recovery would be

AC C
mediated toward customer loyalty via satisfaction after recovery and customer satisfaction. The results of all hypotheses tests in this study are summarized in Table
< Insert Table 6 about here > < Insert Table 7 about here > < Insert Table 8 about here >
Lastly, because the results might have been influenced by including samples with different attributes, we conducted a one-way analysis of variance (ANOVA) to test whether there were any statistically significant differences between the means of each question item collected from the different sample groups. In this study, firm size was the most representative attribute by which to categorize all samples into five groups, 11
ACCEPTED MANUSCRIPT i.e. less than 50, 50-100, 101-300, 301-500, and more than 501 employees. Accordingly, the ANOVA analysis was conducted based on firm size. The results are summarized in Table 9. In total, nine latent variables were tested in which five were SERVQUAL dimensions used to measure service quality. Since all p-values were not larger than the threshold (i.e. 0.05), the differences between the means of each latent variable collected from different samples groups were not significant. That is, it was

4.4 Discussion and implications
RI PT
determined that the results of our empirical study would not be influenced by different firm sizes.
M AN U
According to the results of our empirical study, some findings and implications can be drawn and are discussed as follows: First, maintaining and strengthening customer loyalty is an important issue for LSCs because they need long-term support from customers to maintain high loading factors in their ships. Although factors that may influence customer satisfaction and loyalty toward LSCs have been investigated in a number of studies in the field of liner shipping (e.g. Shin and Thai, 2014; Thai,
TE D
2015; Chao and Chen, 2015; Yuen and Thai; 2015), service recovery has never been included in these models. Due to weather, ship issues, equipment, and various other issues, service failures are both common and inevitable when running an LSC. The results of our empirical study proved that service recovery has a significant positive
EP
impact on the loyalty of LSC customers, indicating that executives of LSCs should endeavor to implement service recovery and in turn strengthen the loyalty of their
AC C
customers. Second, instead of directly surveying the impact between only service recovery and loyalty (e.g. Chou, 2015), our study identified the complicated nature of the relationship by including service quality, customer satisfaction, and after satisfaction recovery as three mediating variables. To our knowledge, our model is the first to propose such a framework to measure the impact of service recovery on customer loyalty, which suggests more managerial implications. For example, satisfaction after recovery played a key role in the two paths transmitting the impact of service recovery on customer loyalty (i.e. H9 and H11). It not only mediated the impact of service recovery on customer loyalty, but also significantly mediated the effect on customer satisfaction. Therefore, LSCs cannot ignore the importance of 12
ACCEPTED MANUSCRIPT increasing satisfaction after recovery. Third, although the impact of service recovery on customer loyalty via service quality and customer satisfaction was found to be insignificant, the direct positive impact of service recovery on service quality was proven to be significant. Given that service failures inevitably occur when customers use liner shipping services, the results indicated that LSCs should also pay attention to
RI PT
implementing service recovery. That is, since most users of liner shipping services have regular shipment demands, and many have encountered service failures, LSCs must seriously assess recovery strategies in addition to service quality.

5. Conclusions
This study contributes to a comprehensive model that can be applied by LSCs and future researchers to investigate the impact of service recovery on customer
M AN U
loyalty. Compared to the previous literature, the contribution of this study can be highlighted in terms of three aspects. First, the relationship between service recovery and customer satisfaction has been discussed in previous studies (e.g. Dabholkar and Spaid, 2012). However, to our knowledge, no previous study has investigated the impact of service recovery on customer loyalty toward LSCs. In this study, by
TE D
conducting an empirical survey of the users of LSCs, we proved the positive impact of service recovery on customer loyalty toward LSCs. In practice, customer loyalty can be easily damaged when service failures occur, but the positive relationship between service recovery and customer loyalty implies that customer loyalty toward
EP
an LSC can be restored if service recovery can be implemented effectively. Second, instead of deeming service quality to be an independent latent variable (e.g. Chao and
AC C
Chen, 2015), the results of this study first suggest that service recovery is an antecedent of service quality for LSC customers. Because service failures are both common and inevitable in this service context, our findings suggest that service recovery should be included in research models related to LSC service quality in future studies. On the other hand, although the impact of service recovery on customer loyalty via service quality and customer satisfaction was found to be insignificant in this study (i.e. H10), future researchers may wish to test this indirect impact because the test results for H10 in this study were very close to the acceptance threshold. Empirical studies can be conducted in different service industries in addition to the liner shipping industry. Third, our results proved that the positive effect 13
ACCEPTED MANUSCRIPT of service recovery is significantly mediated by customer satisfaction and satisfaction after recovery toward customer loyalty. This finding further highlights the importance of service recovery for LSCs. This is because the continuous support of customers is quite important for LSCs due to costly service perishability. Therefore, enhancing customer loyalty must be a serious concern of most LSCs to maintain the high loading
RI PT
rates for their large ships. The results of this study indicate that enhancing service recovery can help strengthen customer loyalty due to its significant mediating effect.
In addition to the findings and contributions, a few limitations still exist which suggest directions for future studies. First, due to time and data constraints, this study

identified the effects of service recovery on service quality, customer satisfaction, satisfaction after recovery, and customer loyalty. Given that some studies have

decomposed service recovery into three constructs, distributive justice, procedural justice, and interactional justice, to investigate their effects on other industries, future studies may apply these constructs to further identify their impact on customer satisfaction and customer loyalty for LSC customers. Second, some shippers are using liner shipping through ocean freight forwarders or shipping agents instead of contacting LSCs directly. Therefore, it is also worth surveying the service recovery

performed by ocean freight forwarders or shipping agents to increase the completeness of investigating the effects of service recovery on the liner shipping industry. Third, due to time constraints, the samples collected this study were firms

located in Taiwan. Future researchers may wish to collect samples from different countries and compare the results obtained from different sample sets because a
