The Structural Relationship among Perceived Service Quality, Perceived Value, and Customer Satisfaction-Focused on Starbucks Reserve Coffee Shops in Shanghai, China

In today’s increasingly competitive coffee industry, the point of running a good coffee shop is no longer to run a coffee and beverage shop simply, but to focus on the quality of service and the value that customers feel as a result. Previous studies have mainly discussed the customer satisfaction and behavioral intention of restaurants, while few studies have explored the influencing factors of customer satisfaction and behavioral intention of chain coffee shops. Given that the perceived service quality theory and DINESERV model can effectively predict customer satisfaction and behavioral intention, this study took 385 consumers in the first Starbucks Reserve flagship store in China as survey objects. SmartPLS 3.0 software was used to explore the relationship among respondents’ perceived service quality, customer perceived value, satisfaction, and behavioral intention. The results show that service quality has a partially significant positive effect on perceived value. Perceived service quality and customers’ perceived value both have significant positive effects on satisfaction. Customers’ satisfaction has a significant positive effect on their behavioral intention. These results indicate that enterprises should strengthen the emotional bond between consumers and enterprises and improve the reliability, assurance, and empathy of perceived service quality to create a better emotional resonance between consumers and the Starbucks brand to improve customer satisfaction. At the same time, it should also promote the symbolic perceived value of Chinese consumers to Starbucks to realize the sustainable development of coffee-shop operation and consumer repurchase. This study expands the research on the service quality, perceived value, and behavioral intention of coffee chain enterprises in the context of non-habitual coffee-drinking countries. Moreover, it provides case support for the operation and research of regional cultural consumption habits of international catering chain enterprises.


Introduction
Coffee is one of the most widely used non-alcoholic beverages, and its consumption is spreading globally. It is the second most crucial commodity exchange after crude oil in the world market [1]. Unlike the West, which regards coffee as a daily drink, China is a nonconventional coffee drinker who prefers traditional beverages, such as tea. In recent years, the acceptance of coffee has gradually been changing in China. Since 2010, the production of coffee beans in China has been increasing by the year. In 2016, the total output reached a maximum of 160,300 tons. In 2019, China's coffee bean production was approximately 144,300 tons, an increase of nearly 100,000 tons over 2010. Coffee consumption in China also shows a trend of increasing. According to statistics from the Global Coffee Industry Trends released by the US Department of Agriculture at the end of June 2020, from 2019 to 2020, China's coffee consumption was 3.25 million bags, equivalent to 195,000 tons (

Perceived Value
The development of the customer perceived value (CPV) theory originated from the thinking of product value by two management scholars, Peter F. Drucker and Michael E. Porter, in the last century. Given its importance in the field of service marketing, research on perceived value has received extensive attention [11][12][13][14]. Perceived value usually involves the trade-off between what customers get and what they give up to obtain service [15,16]. Studies related also believe that perceived value is a "consumer's overall assessment of the utility of the product (or service) based on the perception of what they have received and what they have given" [15]. More specifically, perceived value comes from the trade-off between perceived benefit and perceived cost [17]. Based on this conceptual feature, existing studies have shown that perceived value can effectively predict customer satisfaction and behavioral intentions [18][19][20][21][22].
Although perceived value is a hot topic in related academic fields, there is no consensus on its definition. It is described as the customer's utility, or the ratio of perceived benefits relative to sacrifice, quality, value, etc., according to the different context. In the catering industry and service industry, this study believes that perceived value represents the overall evaluation of the utility of the product or service after weighing the perceived benefits of customers and the cost of acquiring the product or service. It embodies the customer's subjective perception of the value of the products or services provided by the company, which is different from the objective value of the products and services. The concept of customer perceived value is gradually accepted by people and is used when conducting in-depth research. There have been extensive discussions on the operationalization of the concept on perceived value. The common ones are mainly two-dimensional and multi-dimensional frames.
In the two-dimensional classification of perceived value, two frameworks are more popular. One is to divide perceived value into utilitarian value and hedonic value [23,24]. Utilitarian value refers to practical and rational evaluation related to monetary value [25]. It is defined as an overall value assessment that includes characteristics such as quality, convenience, and value for money [26]. Hedonic value is based on the positive emotional response experienced by consumers during the consumption process [27] and is based on sensory experience or emotional satisfaction related to product consumption [28,29].
Another framework is to divide perceived value into symbolic and functional values [26]. Moreover, the functional value represents consumers' overall value evaluation of service or product quality, traditional cost-effectiveness, and convenience characteristics. Its function is to meet the tangible needs of users. In the coffee shop industry, empirical research has been conducted, and Du, Liu, and Sheth have used this dimension classification to conduct in-depth research in service areas such as hotels and electric vehicles [30][31][32]. This kind of classification has been widely cited. Therefore, this study decided to use the two-dimensional classification of functional value and symbolic value to explore the perceived value of chain coffee brand consumers. Symbolic value refers to the overall representative of the experiential value perception from the social, emotional, aesthetic, and reputation aspects, and its function is to meet the intangible needs of users.
In addition, some researchers have proposed a multi-dimensional framework. Sweeney and Soutar designed a four-dimensional perception value framework that includes the functional value (price), functional value (quality), social value, and emotional value [33]. Petrick and Backman developed a five-dimensional framework to measure the perceived value of restaurants, including quality, emotional response, currency prices, behavioral prices, and reputation [20]. Sanchez et al. developed a six-dimensional framework to measure the perceived value of travel agencies, involving the functional value of travel agencies (facilities); the functional value of travel agency liaison personnel (professionalism); and the functional value (quality) of purchased travel packages (quality), price value, emotions value, and social value [34]. The related research shows many different classification methods in the dimensional conceptual framework. However, the focus and content emphasis of these dimensional classifications are pretty different. At the same time, the service environment is rarely considered on the basis of the existing dimensional classification [35]. Because of this, this study decided to use the two-dimensional framework (functional value and symbolic value) based on the service perspective of Chen and Hu to explore the perceived value of chain coffee brand consumers [26]. This framework has been extensively empirically tested in service industries such as hotels and electric vehicles [30,31]. Furthermore, functional value and symbolic value can also cover the related content in several other dimensional frameworks, which has universal significance [26]. More importantly, the content expressed by functional value and symbolic value is more in line with coffee companies' service and product content and has reasonable objectivity and maneuverability.

Perceive Service Quality
Since the 1970s and 1980s, with the development of the global economy, people's consumption structure has been continuously upgraded, and the proportion of service consumption has become higher and higher. The research on service quality in the academic world has been enduring. Grönroos defines service quality as the result of a comparison of consumer expectations and perceptions. He pointed out that service quality is consumers' subjective feeling, which is the combination of consumers' expectations and the actual perception of the service [36]. If the actual service meets or exceeds the expectation, it will be beneficial to the enterprise. Gronroos, Parasuraman, Zeithaml, and Berry (PZB) believe that service quality is a subjective evaluation of customers after a series of studies relating banking, securities brokerage, and other service industries [36,37]. A large number of studies also believe that service quality is the comparison between expected service and perceived actual service [38][39][40][41]. Although service quality is a hot topic in the academic area, the definition has not yet been unified.
Extensive investigations have been conducted on the measurement of perceived service quality. The most famous one is the SERVQUAL model established by Parasuraman et al. [37]. This model is composed of two parts: consumers' expected service quality and perceived service quality. Moreover, it is divided into five dimensions: reliability, responsiveness, assurance, tangibles, mobility, and empathy. Responsiveness indicates a quick response and the ability to get help if there is a problem or question. Tangibles refers to the physical surrounding and appearance of employees. Reliability stands for the extent to which all the service functions operate typically and consistently, with problems that arise being solved on time [42][43][44][45]. Assurance indicates the ability of employees to inspire trust and confidence. Empathy shows the individualized attention provided to customers. The evaluation of the SERVQUAL model depends on the degree of difference between the perceived service level and the expected service level by the user. The key to providing high-quality services is to exceed the user's expectations.
Based on the SERVQUAL scale, Steven developed the DINESERV model for the service quality aim at the catering industry [46]. The DINSERV model is derived from the SERVQUAL model, which is an optimization and improvement of the SERVQUAL model. The model believes that customers can tell which restaurant meets their psychological expectations and value standards. Restaurants that fail to meet the standards will soon see a decline in the number of customers. DINESERV is a reliable and relatively simple tool for determining the evaluation of perceived quality. Its dimensional structure is the same as that of the SERVQUAL model (reliability, assurance, accountability, tangibility, and empathy). Later studies have further developed dimensions to measure the service quality of different industries, such as the service quality of group package tourism GPTCCC [47], the theme parks [48], festivals [49], electronics [50], casino [51], e-government [43], and hot spring hotel [52,53].
In the catering industry, the DINESERV model has been extensively tested and accepted. Compared with the SERVQUAL model, the DINESERV model focuses on the catering industry. At the same time, existing studies have used the DINESERV model to measure the service quality of coffee shops [54]. In view of this, considering that the target object of this research was coffee-beverage service, this research used the DINESERV model to explore the service quality of chain coffee brands. In addition, this research conducted only empirical research on perceived service quality. The reasons are as follows: First of all, this research is a survey of consumers in a non-coffee habitual country. The purpose of the research is to explore why and how consumers produce satisfaction and a willingness to repurchase to coffee, an unusual beverage. Therefore, the investigation of perceived service quality is a direct response to research purpose. Second, due to the strategic location of the Starbucks in Shanghai flagship store, the flow of people is relatively large, and the Starbucks brand has a long-standing reputation in China. Therefore, investigating consumers' actual perceptions of coffee-shop service quality is far more practical than exploring their expectations.

Customer Satisfaction
Customer satisfaction (CS) is an important part of marketing. Since American scholars in the 1960s proposed it, it has been a hot topic in academic research. Cardozo pioneered the use of empirical research to analyze customer satisfaction. He pointed out that customer satisfaction is mainly influenced by two factors: consumers' expectations of products and services and the actual products or services they have obtained. The level of customer satisfaction is determined not only by the quality of the products or services but also by way of acquisition, and customer satisfaction is the core factor affecting consumers' repeated purchase behavior [55]. Since then, scholars from all walks of life have begun to study customer satisfaction from different perspectives. Howard and Sheth found that customer satisfaction is based on the consumer's ability to pay and obtain. Lee and Goudeau argued that satisfaction is an assessment of the matching degree of perceived value and a psychological state resulting from it [56]. Oliver believed that customer satisfaction is the embodiment of consumers' psychological satisfaction, and consumers experience is the basic function of products or services. In the context of the resulting degree of pleasure [57], Churchill pointed out that customer satisfaction is the inner comparison of consumers, resulting from the consumer's income after using the products or receiving related services. In the context of the comparison cost [58], Crompton and MacKay claimed that customer satisfaction is the consumers' perception, and this perception arises after consumers' experience expectations of products or services. Then, the result of this comparison is customer satisfaction [59]. Customer satisfaction belongs to the category of emotional factors produced by comparing the post-consumer sensory system with the level of psychological expectations. The level of customer satisfaction depends on consumers' evaluation of service quality, which in turn affects consumers' willingness to consume next time [60].

Behavioral Intention
Behavior intention is a measure of customer loyalty to the product that shows customers' repurchase and recommendation intention. Customer loyalty is consumers' preference to choose products or services, indicating that consumers may have repeatedly purchased the brand product many times. The intensity and duration of such consumption is customer loyalty. However, this repeated purchase process has not yet been explained in detail, and the research also has a certain degree of subjectivity. Subsequent studies have shown that preference for repeat purchases may be result from spatial convenience or a regional monopoly of product type. If competitive products appeared or are purchased more conveniently, this preference may be eliminated. Olive reviewed the research gap in prior studies, defining customer loyalty as the inherent persistent purchase preference, which will not change due to the change of sales environment or practices but is a kind of continuous consumer credit attitude. However, Gremler et al. believed this definition ignores consumption behavior and considers customer loyalty a combination of behavior and attitude. In this context, customer loyalty means consumers' continuous purchase of certain products or services and their positive perception of the purchase process [61]. Therefore, the discussion about customer loyalty focuses on behavioral loyalty and attitude loyalty. However, behavioral loyalty is difficult to measure objectively, and it is susceptible to many factors. Therefore, judging the behavior intention of customers through attitude loyalty has become the mainstream research method.
In the 1990s, studies on behavior intention emerged in the service categories or products such as hotels, resorts, tourist commodities, or entertainment projects in tourismrelated industries. As behavior intention is affected by customers' subjective and external environment, factors such as tourism motivation, perceived value, and perceived risk will have certain positive or negative impacts [57,61].
By analyzing the above loyalty and behavior intention literature, this study holds that the behavioral intention represents the customer's preference and trust, the willingness to purchase repeatedly, and the willingness to recommend a certain brand to families or friends.

The Relationships between Service Quality and Perceived Value
There is an important relationship between the customer perceived service quality and perceived value [45]. In the context of coffee shop service, Wang and Yu developed a perceived value model and then conducted empirical research where service quality has a positive impact on perceived value [29]. Ali et al. pointed out that good service quality can improve customers' perception of the value of a product or service. If the quality of service is excellent, then customers will be satisfied, and the perceived value will be higher [62]. Bashir studied the relationship between service quality and perceived value in the field of electronic banking. It is found that, the higher the service quality, the higher the perceived value of customers using e-banking [45]. Chen and Hu found, in an empirical survey, that, the higher the service quality, the higher the perceived value in the field of marketing [26].
In the research of the relationship between quality and perceived value, most of the empirical studies have pointed out that service quality positively influences perceived value [26,27]. Therefore, the relationship between service quality and perceived value is examined hypothetically, and the hypotheses are developed as follows: Hypothesis 1. Perceived service quality has a positive effect on perceived value.

The Relationships between Perceived Service Quality and Satisfaction
Perceived Service quality is committed to improving customer satisfaction and the company's market share [37,[63][64][65]. The relationship between service quality and satisfaction has been extensively verified in various studies. For example, Pakurá and Raza both found that, the higher the service quality of the bank, the higher the degree of customer satisfaction [44,60]. Marinković et al. believes that the high level of service quality of travel agencies is related to tourists' high level of satisfaction, and there is a significant positive correlation between them [66]. Zeithaml et al. explored the catering service industry and found that customers' perception of service quality is the key factor in customer satisfaction [67]. Other studies also verified this conclusion and got similar results [44,66]. In summary, most existing studies believe that service quality has a significant positive impact on satisfaction. Therefore, this study puts forward the following hypothesis about the relationship between service quality and satisfaction: Hypothesis 2. Perceived service quality has a positive effect on satisfaction.

The Relationships between Perceived Value and Satisfaction
Perceived value is considered to be one of the determinants of customer satisfaction. Studies have shown that perceived value strongly affects customer satisfaction [12,68]. Wu et al. explored the relationship between patients' perceived value and satisfaction in the field of medical tourism and found that, the higher the patients' perceived value, the higher their satisfaction [69]. Eid explored the relationship between perceived value and satisfaction in the tourism industry [70]. The study found that, when tourists obtained psychological and emotional satisfaction during the travel process or believe that their cost has received the corresponding service, their satisfaction will be significantly improved. Related studies on the relationship between perceived value and satisfaction mostly agree that service quality has a significant positive impact on satisfaction [45,71,72]. Therefore, the relationship between perceived value and satisfaction is assumed as follows: Hypothesis 3. Perceived value has a positive effect satisfaction.

The Relationship between Satisfaction and Behavior Intention
Many studies have shown that customer satisfaction can positively promote their behavior intentions [26,30,73,74]. Changes in customer satisfaction levels will directly affect their intention to revisit, repurchase, and word-of-mouth communications. Therefore, this study assumes the following assumption about the relationship between customer satisfaction and behavioral intentions.

Hypothesis 4.
Satisfaction has a positive effect on behavior intention.

Study Location
This survey was conducted at the Shanghai Starbucks Reserve coffee shop. It was chosen as the study location focus for two reasons. Firstly, Shanghai is a worldwide city in the world. It was listed as the global financial center, ranking third in the Global Financial Centres Index ("GFCI 28 Rank"), after New York and London. [75]. Furthermore, Shanghai is China's economic, financial, and trade center. It was approved to establish Shanghai Free Trade Zone in 2013 [76]. Moreover, it achieves a significant position in the world of finance and commerce, ranking 5th in the world in 2020 [77]. Nowadays, it is the second most-populous city in China [78].
Another reason is that the world's biggest Starbucks coffee shop, the Reserve Roastery, was opened at Nanjing Road in Shanghai and measures with 30,000 sq. ft. (2787 sq. meters). Nanjing Road in Shanghai is equivalent to New York's Fifth Avenue and France's Champs Elysées. This street is famous for luxury shops and various high-end shopping malls [79]. Since opening in December, the cafe is usually packed with customers and, at peak times, has a line out the door. As the first Starbucks Reserve Roastery and Tasting Room outside the United States, the Shanghai Starbucks Reserve Roastery has welcomed an average of 8000 customers every day since its opening, with about 40 percent of its customers coming from overseas [80].
China has gradually become an indispensable partner for Starbucks Corporation. In terms of China's coffee-market-share ranking, Starbucks has a market share distribution of 51%. With the increasing number of Starbucks stores, the return rate is increasing year by year and higher than in other countries. In the future, China will surpass the US and become the largest market for Starbucks' global revenue [80].
When one enters the Starbucks Reserve Coffee shop, one will find that the store has taken great care to set up a coffee-bean-roasting facility in the center of the first floor and a large Chinese bronze bucket with tea drinks. There are also various coffee-related cultural displays and specialty chocolate and bread booths. The second floor is Starbucks' tribute to the tea industry, TEAVANA. It is just as impressive as the coffee bar. In addition to tea, the second floor features a cold-brew-coffee area, a pastry and bakery counter, another brew station, and a coffee bar, as well as a roaster. There is plenty of seating on the second floor for people to sit and enjoy their drinks and occasionally hear the sound of coffee beans shooting out of the pipes above. The menu of Starbucks Reserve in Shanghai is quite extensive. Their unique marketing approach has attracted many residents and coffee-loving Starbucks tourists from all around the world to flock to the Starbucks Reserve Roastery to experience it. People visiting Shanghai today have a huge passion for this coffee shop. Opened on 5 December 2017, the Shanghai Starbucks Roastery is now a commercial landmark in the city, and it was also listed in the 2018 Shanghai Industrial Tourism Attractions Demonstration Unit. In general, Starbucks Reserve Roastery is not only a coffee chain. It is also a tourist destination with the characteristics of coffee culture display and dissemination. This is also the main reason why we selected this iconic case site for our study [79].

Questionnaire Development
Based on the requirements of DeVellis [81] and Churchill and Gilbert [82] on questionnaire development and dimension management, this study developed a self-administered questionnaire for empirical research on the relationship between service quality, perceived value, customer satisfaction, and behavioral intention. The self-administered questionnaire consisted of four sections: Firstly, DINESERV (service quality), with five dimensions, by Steven et al., was adopted in a coffee chain brand to understand customers' service needs and perceptions for service improvement. The five dimensions are reliability, assurance, responsiveness, tangibles, and empathy, with 29 indicators in total [15,60,65,83]. Secondly, the perceived value, which had two dimensions (symbolic value and functional value) with eight indicators, was adopted from the theory of perceived value demonstrated by Zeithaml et al. [65], Eid [70], Yen and Teng [84], Albrecht [85], and El-Adly [72] to measure consumers' perceived value after experiencing a Starbucks Reserve Roastery versus the cost of the product or service. Thirdly, the customer satisfaction section had four indicators adopted from Cardozo to measure the customers' satisfaction on Starbucks Reserve Roastery in Shanghai [55]. Fourthly, the behavioral intention section had two indicators adopted from Tucker to explore customers' intention to revisit and spread word of mouth about Starbucks Reserve Roastery [86]. Finally, the demographic profile section was composed of gender, age, occupation, education level, and monthly income level adopted from Song et al. [87]. In the first five sections, all the indicators were measured on a five-point Likert scale ranging from 1 = "strongly disagree" to 5 = "strongly agree".

Data Collection and Analysis
The survey was conducted from 21 to 30 August 2018, in Shanghai, China. A selfadministrated questionnaire was used to collect samples. Five hundred samples were sent out to the customers in Shanghai Starbucks Reserve Roastery, and 450 questionnaires were collected. Three hundred eighty-six samples were finally retained after excluding the invalid samples due to incomplete and not serious enough, with an effective rate of 85.7%.
In this study, SPSS 24.0 and SmartPLS 3.0 were used to analyze the data. Descriptive analysis was undertaken by using SPSS 24.0. The measurement model, structural model, and the proposed hypotheses were tested by using the partial least squares structural equation model (PLS-SEM) through SmartPLS 3.0. Compared to the traditional covariancebased SEM, PLS-SEM is preferred for theory broadening and development, especially for predicting a target construct (e.g., behavioral intention) [88].

Respondents' Profile
In this part, descriptive analysis is utilized to show the characteristics profiles of respondent's characteristics. Table 1 shows the gender, age, occupation, education, income, frequency of coffee shop visits, and marital status of the respondents. The demographic profile of this study's research subjects is as follows: The proportion of female respondents (60.9%) is higher than that of male (39.1%). In terms of age, most of the respondents were in the 25-34 age range (45.3%), and the remaining 15-24 years old, 35-44 years old, and 45-59 years old accounted for 28.5%, 11.4%, and 14.5%, respectively. Respondents' occupations involve students (18.7%), sales and service personnel (7.5%), technicians or academicians (14.2%), office workers (32.1%), self-employed workers (6.0%), retirement and unemployment (5.4%), professors and teachers (4.9%), and others (11.1%). Half of the respondents' academic qualifications are college (54.9%), followed by high school (23.3%), master's or doctoral degree (19.9%). In terms of income, the monthly income of the respondents is mainly distributed in the range of 0-6000 yuan (36.8%) and 6001-12,000 yuan (33.7%), with 12,000 yuan or more accounting for 29.5%, specifically 12,001-18,000 for 14.2%, 18,001-24,000 is 4.9%, and 24,001-30,000 is 3.9%. Most people visit coffee shops less than 3 times per month (54.4%) or 4-7 times per month (30.8%). In terms of marital status, 65.5% of the respondents were unmarried, and the remaining 34.5% were married.

Measurement Model
As mentioned earlier, the proposed research model was estimated with PLS-SEM, using SmartPLS 3.0. According to Hair et al. [89,90], the model fit of the measurement model can be performed by using criteria such as factor loading (>0.7), composite reliability (CR) (>0.7), Cronbach's α (>0.7), and average variance extracted (AVE) (>0.5) to achieve. Then, the AVE values should be greater than the squared inter-construct correlations of corresponding constructs to gain a better discriminative validity [91]. Table 2 shows that all factor loadings were above the cutoff value of 0.7 and AVE values were above the required criteria of 0.5, thereby confirming convergent validity of the measurement model. Cronbach's α and CR were also above the required criteria of 0.7, thereby supporting the reliability of the model. Table 3 shows that all square roots of the AVE values were greater than the correlations of the corresponding constructs, which confirms discriminant validity [91].

Discussion and Implications
This study explores the relationship among service quality, perceived value, satisfaction, and behavioral intention of the brand chain coffee shop by taking the visiting customers of Starbucks in Shanghai flagship store as the survey objects. The study results explain why and how Chinese coffee consumers decide to visit Starbucks Reserve Café Shanghai. This study is of great significance to guide coffee chain enterprises and their marketing personnel to achieve higher coffee-brand stickiness.
In developing countries, especially those that are non-conventional coffee-drinking countries, it is necessary to pay attention to the adaptability of the existing dimensional framework and evaluation system of perceived service quality. In this study, the responsiveness and empathy of service quality do not significantly affect the functional perceived value and symbolic perceived value. Service-quality guarantee, service-quality responsiveness, and functional perceived value do not significantly determine customers' satisfaction. Therefore, the existing service quality and perceived-value framework need more adaptive discussions in developing countries and non-conventional coffee-drinking countries.
In terms of practice and management implications, this study provides some management and marketing suggestions for service-oriented enterprise managers from Starbucks' business perspective. First, improve the quality of service. The research shows that perceived service quality is an essential factor that affects customers' perceived value. Business operators can organize professional skills and individual quality training to service personnel to provide accurate services to customers quickly. At the same time, besides intangible services, such as the professionalism and attitude of service personnel, operators also need to pay attention to store decoration and facade design to reflect a tangible atmosphere that matches the brand and product. In addition, the number of parking spaces (including parking services), the sanitation in the coffee shop, and the dressing of service personnel are also in the area of service quality improvement, which coffee-chain store operators need to consider. For example, service personnel should carefully observe consumers' demands for products and promptly inform the product's taste, the suitability of the crowd, and optional choice. Let them feel the responsiveness and guarantee in the service process and enhance their relationship with the customer coffee shop so that emotional connection can be promoted and subjective evaluation can be improved.
Second, improve the customers' symbolic perceived value. The conclusion shows that the perceived symbolic value of customers will positively affect customers' satisfaction. Therefore, it is vital to enhance the symbolic perceived value of customers. Coffee-shop managers should focus on establishing deeper communication and contact with coffee consumers in emotional and psychological aspects, such as psychology, emotion, aesthetics, and reputation. For example, targeted-language and body-language training can be used to improve the expression of employees so that customers can generate more robust emotional feedback in the consumption process. In addition, business operators can also use creative and content-oriented advertising strategies to deepen the brand image, respect, and emotion in the consumers' market, and then rely on excellent brand prestige to affect consumers' emotional value and social value indirectly. In this way, the enterprise can realize the promotion of customer satisfaction, the guidance of repurchase behavior, and the formation of a good reputation.
Finally, pay attention to the sustainable development of services. Whether it emphasizes service quality or the management of symbolic perceived value, the ultimate goal is to improve customers' satisfaction and behavioral intentions(loyalty). From the perspective of the service process, positive customer satisfaction and behavioral intentions mean that service production and consumption have achieved a sustainable cycle. In the context of sustainable development goals (SDGs) advocated by the United Nations, coffee-shop managers should focus on improving the sustainability of the service process. This kind of sustainability is embodied in the change-of-service concept from customer-centric to life-centric. At the macro-level, customers' needs should be placed at the core of business operations while maintaining the dynamic balance among corporate profitability, customer perceived value, coffee-product-manufacturing technology, and the coffee market environment are vital to achieving goal-driven marketing. At the micro-level, this requires managers and operators to simplify the complex service process to create a valuable coffee-consumption experience. For example, enterprises can continue to promote the low-energy-consumption materials for coffee packaging and store decoration, the usage of energy-saving electronic products, and self-carrying food containers.

Conclusions
This study explored the relationship among service quality, perceived value, satisfaction, and behavioral intention of the brand chain coffee shop by taking the visiting customers of Starbucks in Shanghai flagship store as the survey objects. The study results explain why and how Chinese coffee consumers decide to visit Starbucks Reserve Café Shanghai. This study is of great significance to guide coffee chain enterprises and their marketing personnel to achieve higher coffee brand stickiness.
The results show that the service quality of branded chain coffee shops has a partial significant positive impact on perceived value [18,93,94] which agrees with the study of Park's [95]. Among them, the dimensions of reliability, assurance, tangibility, and empathy of perceived value have significant positive effects on symbolic value. This conclusion is consistent with the previous research of Lai and Chen that determined that high-quality service quality can effectively improve the symbolic value of customers' perceived value [96].
The better the professionalism of corporate service personnel, the better the external image of the company, and the higher the ability to meet the needs and wishes of customers, the more likely it is for customers to obtain the symbolic value brought by social emotions, aesthetics, and reputation.
In addition, if the staff in the coffee shop are highly professional, and the equipment, personnel, and communication carriers related to the service can better maintain the consistency and professionalism, then customers can feel that the cost they have paid in obtaining services is worthwhile, and they have obtained satisfactory service quality. This is consistent with Tam's study, which finds that higher quality reliability, assurance, tangibles, and service quality can effectively enhance the functional value of the customer's perceived value [94].
However, in this study, good responsiveness during the service of Starbucks could not significantly promote the generation of functional perceived value and symbolic perceived value, which was contrary to the previous research conclusions. The possible explanation is that, in this study, the subject was Starbucks Reserve Coffee Shop, which is very large, located in Shanghai. Moreover, the massive queue has been the norm because of the prosperous location and large customer flow. At the same time, in recent years, many chain tea brands have emerged in China whose consumers often have to queue for more than one hour to get the products they need [97]. To some extent, Chinese consumers have better patience with famous brand chain catering enterprises. Therefore, consumers' perceived efficiency of service personnel in handling consumer needs during peak hours does not affect their evaluation of Starbucks' functionality and symbolic value and products.
In addition, this study also finds that empathy in service quality has no significant positive impact on functional value in perceived value, which is contrary to some previous research conclusions. Possibly because coffee is a gourmet experience, the quality of the experience is determined by the taste and flavor and has little to do with the emotional exchange and communication in the service process. As a result, the empathetic services that customers receive during the consumption process may not be enough to make them believe that the price they paid is the proper return.
This study also shows that service quality has partial significant positive effects on satisfaction. Reliability, tangibles, and empathy in service quality are essential prerequisites for determining customer's satisfaction. Such a conclusion is consistent with some study results [44,93], which show that a higher trust in the coffee shop, a better evaluation of internal facilities, and more attentive service perceived by customers can lead to a higher level of satisfaction.
However, the study also finds that the guarantee and responsiveness of service quality did not significantly positively impact customer satisfaction, which is contrary to previous studies. The possible explanation is that Starbucks coffee has a good brand effect and customer stickiness in China, and all kinds of coffee products have a good reputation and emotional identity. At the same time, the Starbucks Shanghai flagship store has been meticulously planned in terms of decoration, atmosphere, and service. Therefore, during consumption, customers' satisfaction may not be determined by the guarantee and responsiveness of the service quality.
The symbolic value of perceived value has a significant positive effect on satisfaction [93]. This conclusion indicates that, the better the customers' experience (including psychology, emotion, aesthetics, and reputation) in the process of enjoying the service in the coffee shop, the more likely they are to get a better satisfaction level. However, functional value of perceived value does not significantly positively impact satisfaction in this study, contrary to the existing research conclusions. The possible reason is that symbolic value, which represents how customers improve their views of products and services and how they enjoy themselves in fashionable coffee shops with good reputations, which is a decisive value perception beyond functional value [26].
The findings confirm that higher customer satisfaction could increase behavior intention. The quality of satisfaction is an essential factor for consumers to decide whether to continue buying Starbucks coffee [93,98]. In short, the more satisfied customers are with the service they enjoy in the Shanghai Starbucks flagship store, the more likely they will revisit the coffee shop and convey an excellent word-of-mouth [26].
The potential contributions of this research are as follows: First, this research explored the relationship and mechanism of consumers' perceived service quality, perceived value, satisfaction, and behavioral intentions in the context of non-conventional coffee-drinking countries. In this study, we found that coffee is a common and popular daily drink in Western countries, while Asian countries, represented by China, Japan, India, and Sri Lanka, are different. Tea is the main beverage for daily consumption. Therefore, many Chinese consumers are not accustomed to drinking coffee that tastes sour and bitter, different from traditional sweet or fragrant beverages. Given this, this study further explored the perceived service quality, perceived value, and behavioral intentions of consumers in the non-conventional coffee-drinking countries to Starbucks, a well-known global coffee chain company. In previous studies, service quality and perceived value are often applied to restaurants in Western countries. Therefore, this study expanded the application areas of the relationship between related variables. It also offers a gaze and evaluation of Starbucks and the coffee-beverage industry from an Asian perspective.
Secondly, this research discusses the application of the DINESERV framework in coffee chains, especially in developing countries. The framework has been widely used in developed countries and restaurants before [46,[99][100][101][102], but the research conclusions further extend the application scope of the service quality.
Thirdly, the study found some interesting conclusions. For example, responsiveness and empathy of service quality cannot determine functional perceived value. At the same time, the guarantee and responsiveness of service quality and the functional value of perceived value cannot determine consumer satisfaction. Therefore, it can be inferred that, in non-conventional coffee-drinking countries, beverages such as coffee have to rely on taste and quality to attract consumers. The traditional service quality and perceived value framework cannot fully interpret why and how consumers are satisfied with related products and their behavioral intentions. This conclusion expands the consumer's understanding of the satisfaction evaluation of coffee products, repurchase, word-of-mouth (loyalty), and user stickiness.

Limitations and Future Research
This study has some limitations. The limitations of the study are mainly three kinds. First of all, because the object of the study is China's commercial center, Shanghai, the current results can only explain the consumption propensity of consumers in China's first-tier cities to a certain extent. However, on a China-wide scale, the results in this study still need in-depth discussions through more cases and chain coffee brands. Second, according to the attitude theory, the generation of people's behavior requires the process of cognition and emotion. In this research, perceived value, service quality, satisfaction, and behavioral intention are mature models. The related studies emphasize the mechanism of coffee-purchase behavior from a cognitive level. Future research can try more to explore the variables of consumers' feelings about products, such as brand attachment, brand preference, etc., to explain the process of brand stickiness better. Finally, since the empirical investigation of this study was conducted in 2019, the respondents were not severely affected by the COVID-19 epidemic. China's business is rapidly recovering in the context of China's stricter epidemic prevention and control policies. The impact of the epidemic on the behavioral intentions of Chinese coffee consumers still needs to be further explored. Therefore, it is necessary to re-verify relevant content in the post-epidemic era.
