Vietnam is not an exception Vietnam banking industry has gained a significant growth in recent years a long with the socioeconomic development Many banks have been established or extended their range of activity by setting branches in nationwide and offered new services toward customer’s need Retail banking in Vietnam is one of the sectors getting more attractive from domestic banks or even foreign banks with the potential market has not been exploited full enough so far A lot of people among 86 million Vietnamese people have demands for retail banking services which are going up following the increasing income and the growth of the country in recent years especially after Vietnam became a member of WTO This is the chance as well as the challenge period for bankers in Vietnam to attract the new customers and retain the existing one The more customers banks have, the more profits they get Satisfying customers is the priority target in order to get the success of a firm Customer satisfaction is one of the key factors in today’s highly competitive business world and is the most important factor for bankers to keep their current customers as well as appeal the new one In addition, retail banking industry is facing a stressful competition among domestic banks and foreign banks as the globalization and world integration Therefore, banks should pay more attention to customer satisfaction to survive and grow 1.2 Statement of the problem Domestic banks have recognized the important to develop retail banking services for some time now They have invested in core banking software, applied new technology, established more branches, provided new services to get more customers In modern competitive environment, however, the increasing of distribution channels set up from all banks, the products in this market are slightly different and the new services provided are matched very quickly by competitors make banks in difficulty to create the differentiation Customer satisfaction is one of the main tools for banks to make and get competitive advantage In general, when customer is satisfied with provided services, the probability to use this service again is increased and will lead to the positive advertising through mouth advertising from this customer to others And vice versa, the unsatisfied customer usually switches to use another brand and give out the negative mouth advertising There are many factors impact on customer satisfaction Customer satisfaction is influenced by main factors such as price, product quality, service quality, personal factor, situational factor, diversification and the unique of products According to Lewis (1993), service quality is one of the effective means in building a competitive position in service industry Service quality is an imperative element impact on customer satisfaction in banking industry Thus, bank management tends to differentiate their products from competitors through service quality This study examines determinants on customer satisfaction with focus on service quality dimensions of retail banking services in Vietnam commercial banks in Ho Chi Minh City where is the center of developing economy, society and education in South Vietnam with a large number of population, almost banks and their branches 1.3 Research Objective The aims of this study as following: - To identify main factors of customer’s perception on customer service quality in Vietnam retail banking sector - To measure the effects of these key factors on the overall customer satisfaction in Vietnam retail banking sector - To recommend some solutions to increase customer satisfaction 1.4 Research question The study is set to answer following questions: - What are the key factors of customer’s perception on service quality of retail banking services in Vietnam commercial banks? - How can these factors influence on customer satisfaction? - What the recommendations should be needed to improve customer

using retail banking services of seven Vietnam commercial banks in Ho Chi Minh City only The conclusions will be derived from this research are limited to Vietnam commercial banks and will be based on the information of this result 1.6 Research methodology Secondary data Data was collected from annual Vietnam commercial banks reports, from internet, involved books and previous related research

result of this research is used for designing the questionnaire used for official study Quantitative research: This step is researching by delivering questionnaire to individual customers of seven commercial banks in Ho Chi Minh City directly, via email and internet The collected data is used for analyzing the level of customer satisfaction through statistical software SPSS version 16.0 1.7 The structure of the research This research includes five chapters: Chapter 1: Introduction This introduction gives an overall view of the research includes the rational of the research, statement of the problem, research objectives, research questions, scope and limit of the research and research methodology Chapter 2: Literature review This chapter gives a brief introduction about Vietnam retail banking industry and general view of theories related to customer satisfaction, five gaps of service quality, service quality and some results of previous studies about dimensions of service quality in banking sector Chapter 3: Research Design This chapter develops the research model and hypotheses In addition to, we focus on research process and methodology for data analysis Chapter 4: Data analysis and findings This chapter illustrates the process of data analysis and shows the result of this research from that we can explore the result and discussion Chapter 5: Conclusions and recommendations This chapter summarizes the most important findings, provides recommendations on how to improve customer satisfaction on retail banking services of Vietnam commercial banks Lastly, we
