Customer satisfaction is the main pillar for convenient and profitable retailing. The retail sector continuously tried to develop new strategies to improve consumer satisfaction. It is impossible to provide each service directly to the consumer by the retailer. In this direction, the retailer establishes customer care to provide the best service to consumers. Consumer care can provide promotional or prevention services, increasing the consumer's satisfaction level. This study is developed to show the impact of retailers' customer care service for an offline-to-online retailing strategy. The demand is consumer support, advertisement, and selling price dependent. For maintaining consumer service, some free home delivery policies are offered, when consumers ordered more than a certain percentage of the amount. Finally, the total profit of this O2O retailing system is calculated by the classical optimization technique. Some special cases are discussed in the numerical section to prove the impact of customer care services. Numerical results prove that customer care support enhances the profit by 48.20%, whereas investment in the advertisement and home delivery strategy helps the retail industry to earn 44.80% and 16.74% more profit, respectively. Finally, from this study, it is clear that customer care activities are essential to increase the profit of the retailing sector.  相似文献

Online meal delivery platforms (OMDPs), like UberEats, have received more attention since quarantine was established to prevent the spread of COVID-19. The research into antecedents of satisfaction and continuous usage intention for OMDPs, in general, is under researched. The current study compared the antecedents of satisfaction before quarantine to the antecedents during quarantine through the lens of Expectation-Confirmation Theory. Through multiple regression analyses, the researchers found that before quarantine, sharing economy ethos, price-value, food quality, ease of use and confirmation of beliefs had a significant impact on satisfaction while during quarantine, food quality, service speed, ease of use, and confirmation of beliefs were significant. Practical and theoretical implications are discussed.  相似文献

The growth in mobile communications is a significant reason attributed to the O2O commerce explosion in China. Mobile applications have seized this opportunity adapting it to restaurants and food delivery services, recognized as an alternative strategy to increase sales revenue and for consumers to conveniently receive products and services. This study was designed to specifically explore five salient quality attributes representing convenience, design, trustworthiness, price, and various food choices associated with food delivery apps in consideration of their impacts upon user-perceived value, attitudes and intention to continuously use. Results determined that user trustworthiness was the most important quality attribute of the food delivery app business. Additionally, this study found that single-person households placed most importance upon quality attributes for ‘various food choices,’ ‘price’ and ‘trustworthiness.’ Comparatively, multi-person households placed most importance upon ‘design,’ ‘convenience,’ and ‘trustworthiness.’ Managerial implications, limitations and recommendations for future research are provided.  相似文献

ABSTRACT

A study of 216 respondents examined a medical center environment’s influence on patient responses. A stimulus–organism–response (S-O-R) model was adapted to the theory that more hospitable healthcare servicescape elements will affect patients’ overall satisfaction with healthcare experience, loyalty intentions, and willingness to pay out-of-pocket expenses for healthcare services. Servicescape elements included atmospherics of the healthcare environment, service delivery by healthcare staff, physical design of the healthcare environment, and wayfinding. Results of structural equation modeling confirmed that the four servicescape elements – had a significant impact on patients’ overall satisfaction with the healthcare experience. Furthermore, overall satisfaction with the healthcare experience predicted patients’ loyalty intentions and willingness to pay out-of-pocket expenses for healthcare services. The study makes a significant contribution to the empirical modeling of patients’ behavioral responses to hospitable healthcare environments.  相似文献

Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.  相似文献

This study investigates possibilities for developing a click and collect service in the context of e-commerce and attempts to identify the consumer characteristics that determine the acceptance of this service. Data of 285 e-commerce consumers were collected through an online questionnaire using banners uploaded in seven online retailers' sites. Binary logit models are developed to analyze the data and relate consumer characteristics to their intention to use and pay for the click and collect service. Perceived environmental contribution of the click and collect service, perceived time pressure, car use in the city center and frequency of online shopping significantly affect consumers’ intention to use the service. The model results provide information that can be used to choose location points and design marketing and pricing policies that will make the click and collect service attractive to customers.  相似文献

Based on the contingency, transaction, and trust theories, this paper explored how the green cooperation between supplier and customer in last-mile logistics contributes to consumers’ sustainable consumption behaviors and trust and transaction cost's contingency role. We collected survey data from 453 users of green shopping platforms in South Korea (e.g., Homepick and Smart Locker) and analyzed the data using structural equation modeling. The results suggest that green cooperation with companies positively affects consumers’ sustainable consumption behaviors and trust, and transaction costs negatively moderate such relationships. In addition, customer trust positively affects sustainable consumption behavior and loyalty. We also found that improved sustainable consumption behavior can form loyalty, but transaction cost decreases its positive impact. This paper evaluates the last-mile delivery through green cooperation and enriches the literature on contingency, transaction cost, and trust theories.  相似文献

Consumers are increasingly using food delivery apps (FDAs) to facilitate convenient and quick food delivery. Yet, the existing research offers a limited understanding of consumers’ behavioral responses to the visibility and values derived from FDAs. Our study utilized the theory of consumption values (TCV) to examine associations between FDA visibility, consumption values, and purchase intentions. The mediating role of consumption values and the moderating role of attitude was also studied. A qualitative study was conducted with 15 FDA consumers to derive context-specific consumption values. Responses from 355 FDA consumers from the United States of America (USA) were obtained through Prolific and analyzed using structural equation modeling. Visibility acted as an antecedent of all consumption values and significantly influenced purchase intentions. Attitude also positively and significantly influenced purchase intentions. Consumption values partially mediated the association between visibility and purchase intention, while attitude negatively moderated the relationship that purchase intention has with visibility and preference value. These findings have important implications for theory and practice.  相似文献
