Introduction The quality of service provided has become a strategic orientation and effective business policy that enterprises have implemented to increase competitiveness and attract customers, an important approach in management. Modern business practices aimed to optimize customer service (Avkiran, 1999; Abu, 2004). Parasuraman et al. (1985) argued that service quality is the distance between customer expectations and perceptions of customers when they purchase and use the service. Service quality was also defined as the ability of a service including overall durability, reliability, accuracy, ease of use, ease of repair, and other valuable attributes for performance. (Dabholkar et al., 1996). In addition, due to the different cultural environment, consumers in different countries may perceive different quality of service for each type of service (Cronin et al., 1992); Nguyen, 2006, 2007). Research on quality of service as well as identifying factors affecting service quality has been of considerable interest to researchers and managers through the development of theoretical foundations (Smith, 1995), identifying the quality of service and verifying the hypotheses of the research model (Thenmozhi & Dhanapal, 2010), thereby recommending improvements in service quality. Since the 1980s, theoretical studies and the empirical model of service quality have begun to propose, in particular, studies by Gronroos (1984), Parasuraman (1985), Cronin and Taylor (1992). Sweeney et al. (1997), and the practical application of service business in Vietnam (Nguyen, 2006). These studies have developed a theoretical framework for analyzing quality assurance with a variety of components, deployed in different service sectors. Therefore, this paper aims to identify the factors 479

Through approaching the models of service quality assessment conducted at domestic and international published in scientific journals as well as business management practices of the enterprise to define the model of researching and evaluating the quality of retail supermarket services in case of economic, distribution and culture in Vietnam. 2. Literature and research model 2.1. Literature There are different perspectives on service quality, reflecting service endeavors of the business and the recognition of customers. Lehtinen & Lehtinen (1982) argued that service quality must be assessed in two respects, one for service delivery and the other for service results. Gronroos (1984) also presented two components of service quality, namely, technical quality - what the customer receives and the functional quality - how the service is provided. Parasuraman et al. (1988) perceived service quality as "the degree of variation between customer expectations of service and their perceptions of service outcomes." Quality-of-service studies use a combination of two qualitative research methods and quantitative methods to develop a scale and verify the scale of components that make up the service quality (called the SERVQUAL scale). The SERVQUAL scale is adjusted and tested in a variety of services, including 22 variables to measure five components of service quality: reliability, responsiveness, assurance, tangibles, and empathy. Since then, many studies have been using the SERVQUAL scale to measure service quality and assess the effectiveness and reliability of industries with different cultural contexts (Mehta et al., 2000; et al., 2003). Retail business in the form of a supermarket is a mixed business between the supply of goods and services, so research on the quality of retail services requires the inheritance and incorporation of the characteristics of this type of service (Dabholkar et al., 1996), reflected in the study of the retail services quality, has provided five basic components of the quality of retail services: shape, reliability, service personnel, complaint resolution, and store policy. Retail service quality scale of Dabholka el al (1996) is condersidered appropriate scale in the retail market because the form of suppermarket business is a mixture of products and services. This study used a retail quality scale (Dabholka et al., 1996) and Nguyen (2006) applied to the retail sector in Vietnam. Based on the research results of authors mentioned above, using qualitative research methods to adjust and supplement the components of the quality of retail supermarket services in economic conditions, distribution and culture in Vietnam. 2.2. Research model and hypothesis Diversity of goods and services Serviceability of staff Supermarket Exhibited in the supermarket service quality Infrastructure and premises Safety in the supermarket Figure 1: Research model The research model is based on the synthesis of variables published in empirical studies, mainly from the work of Dabholka et al., (1996) and Nguyen's work (2006) and and through 480
  3. Kỷ yếu Hội thảo quốc tế “Thương mại và phân phối” lần 1 năm 2018 qualitative research from interviews with supermarket managers, marketing experts, and regular shoppers at established retail outlets in Ho Chi Minh City. Qualitative research results show that the quality of supermarket services is a multidimensional concept consisting of five components, namely (1) diversity of goods, (2) serviceability of employees, (3) ) how to display in the supermarket, (4) supermarket layout, and (5) safety in the supermarket. In general, the components of quality of supermarket services such as staff, supermarket premises, display of goods are similar to the supermarket service quality model of Dabholka et al (1996) and Nguyen (2006). - Diversity of goods and services The diversity of goods and services reflects the richness of the commodities and services that marketed at the supermarket and the services that supermarkets provide to customers, bringing the ability to select and purchase customers, meet the main needs of customers when coming to the supermarket. The goods sold at supermarkets are one-sidedly formed from the purchase relationship of the supermarket with the manufacturers, on the other hand formed from the strategy of developing goods under the brand own supermarket. The variety of goods and services of the supermarket determines the ability to attract customers to meet the needs of customers. Based on the results from previous studies, the first hypothesis is: H1: The diversity of goods sold at supermarkets strongly influences the quality of supermarket services. - Serviceability of staff The ability of staffs to serve shows the number and quality of existing staffs in the supermarket is ready to welcome and serve customers. Supermarket employees with professional service skills, attentive service attitude, caring, customer care and advice to customers during the purchase, support and answer customer questions. It is decided from the previous studies, the second hypothesis is: H2: The ability of the staff at the supermarket to influence the quality of supermarket service. - Exhibited in the supermarket Display is a popular activity that shows the characteristics of the supermarket compared to other types of retail. Exhibits at the supermarket include interior display and arrangement, display facilities, indication information systems, scientific and artistic displays. Exhibiting at the supermarket is of special importance, on the one hand demonstrating in a scientific way and attracting customers to sell items, on the other hand showing persuasiveness and customer orientation when searching and selecting. It helps to decide the quality of supermarket service. Based on the results from previous studies, the third hypothesis is: H3: Displaying in supermarkets strongly influences the quality of supermarket services - Infrastructure and premises Infrastructure and premises indicates physical elements that make up the supermarket and the interior of the supermarket to support and facilitate the customer to access and fulfill the purpose of sightseeing and shopping. Supermarket infrastructure and premises include such factors as the location of the supermarket, distribution of the inside space, the shopping and payment support facilities, parking lots and storage facilities and facilities for keeping customers luggage. Supermarket infrastructure and premises affect the quality of supermarket services. Based on the results from previous studies, the fourth hypothesis is: H4: Supermarket infrastructure and premises strongly affect the quality of supermarket services. - Safety in the supermarket 481
  4. Kỷ yếu Hội thảo quốc tế “Thương mại và phân phối” lần 1 năm 2018 Shoppers at the supermarket always ask for safety. Safety in the supermarket signifies the establishment of a safe mode through means of fire prevention and firefighting, the escape signage system, the presence of security personnel and the state of security in whole supermarket. Once the safety factor in the supermarket is guaranteed, it will create a safe atmosphere for customers to visit and shop, create conditions for customers to stay long in the supermarket and thereby promote safe shopping. Safety factors in supermarkets affect quality of supermarket service. Based on the results from previous studies, the fifth hypothesis is: H5: Safety factors in supermarkets strongly affect the quality of supermarket services. 2.3. Methodology Qualitative research was conducted in the form of discussions with 10 experts working in the field of supermarket business, 10 retail supermarket managers and 30 typical customers shopping at supermarkets. The qualitative research is to identify variables and scales of each variable in the research model. The main study variables of the model are drawn from empirical and qualitative research, as shown in Table 1. Quantitative research was conducted through interviews with 2200 retailers in six retail outlets in Ho Chi Minh City: Coopmart supermarket, Big C supermarket, Maximax supermarket, Metro supermarket, Citimax supermarket and Lotte Mart. The results of the questionnaire were collected for 2000 questionnaires. Variables of the research model were likert scale from 1 to 5. Scale reliability and EFA factor analysis were presented in Table 2. Results of Cronbach's Alpha scale analyzes have high reliability, the correlation coefficients of the variables are equal to the allowable criterion (greater than 0.3) to satisfy the requirement for factor analysis. The EFA exploratory factor analysis using the Principal Component Analysis method and the Varimax rotation for grouping factors show that the components after eliminating the garbage variables are required to have factor load factor of observational variables greater than 0.5 (Hair et al., 2010), Bartlett's test for sig significance = 0.000; KMO = 0.834. The remaining 38 variables were extracted into 5 components with corresponding factors and Eigenvalues values greater than 1, and the extraction variance was greater than 50%. The results of the EFA analysis have shown that the study pattern remains unchanged, consisting of five independent and one dependent components used for linear multiple regression analysis. 3. Results and discussion 3.1. Research hypothesis testing A multiple linear regression analysis of the relationship between factors influencing the quality of the supermarket service was performed by the Enter method and the regression results are presented in Table 3. Thus, goods, staff capacity, display in supermarkets, infrastructure and premises, safety in supermarkets will affect the quality of supermarket services, so the hypotheses H1, H2, H3 , H4, and H5 are acceptable.

  7. Kỷ yếu Hội thảo quốc tế “Thương mại và phân phối” lần 1 năm 2018 The quality of the supermarket service is a multidimensional concept, involving the whole process of providing goods and services of the supermarket on the basis of the minimum business conditions, meeting the needs of sightseeing and shopping. of the customer (Anselmsson, 2006). The quality of retail supermarket services according to actual research shows that it is an integrated concept, as a retailer providing both goods and services. As a result, the quality of the supermarket service represents "a quality shopping destination", "an ideal place for shopping", "space for selling goods and providing modern services", is "a place of quality shopping and a civilized business environment". The business of the supermarket requires the manager to pay attention to all the variables affect the quality, this is to ensure the diversity of goods and services provided, to maintain the sales staff capable of serving and taking care of customers, maintaining the system of infrastructure and supermarkets premises well, ensuring the decoration and display of goods and ensuring the science and art, while ensuring the safety conditions for customers during the sightseeing and shopping. The strategic issue for owner of suppermarket today is to optimize the business conditions inherently in terms of material and equipment, spatial planning that is reasonable and At the same time, developing a spectrum of genuine goods and services that address the needs of customers, creating an environment inside and outside the supermarket that is both safe and civilized and tested. Synchronized policies in the business process, meeting the needs of visiting and shopping of customers. 4. Limitations and future research orientation The quality of service in general and supermarket service in particular is a complex issue not only in the measurement and determination but also in the setting up, strengthening and enhancement to meet the expectations of customers. In the context of intense business and competition, supermarkets are not only to compete with each other to attract customers but also compete with individual retail chains that have existed in the past. This study was carried out only in Ho Chi Minh City, surveying 2000 customers concentrated in 6 large supermarkets with relatively long trading time, so the research results are not fully available to replicate for all supermarkets. Research references are primarily studies in developed countries, although qualitative research has been conducted to determine the suitability of the quality assurance model in terms of economic, conditions and culture of Vietnam. The study did not use the structural model to simultaneously evaluate the combined effect of the variables in the supermarket service quality assessment model. These restrictions will be further studied in the future to provide more scientific and practical research results. The quality of the supermarket service is a vital issue that determines the organization of the supermarket business in a quality way, ensuring that it attracts and maintains the ability to visit and purchase customers, create loyalty of the customer. The form of quality business organizations both in terms of goods and services provided as well as the physical conditions for supermarkets are always the basic motives that form the foundation of quality business. At the same time, all business and implementation efforts must be directed to customers, providing more value to customers, better customer care, contributing to improving business quality and competitiveness for each super.
