The findings of this research are mostly useful to those (managers, web designers, etc.) who intend to penetrate the Cambodian market with least cost, time and energy The results indicate the most important web quality factors through Cambodian online shoppers’ perspective In these recent years, a significant growth has been noticed in the Internet- based services in the pure Internet businesses as well as the traditional enterprises, which are developing their online services One of the key challenges of online businesses is how they manage service quality, which holds a significant importance to customer satisfaction In addition of success stories, we should be aware of problems; in year 2000 nearly 900 US online firms were shut down, 31% of them were online retailers (Minjoon Jun, 2004) The purpose of this research is to rank the quality factors perceived to be most important in relation to the use of online shops The questionnaire utilized was based on the SERVQUAL instrument that identifies five quality dimensions in service environments I 123doc Acknowledgements First of all I would like to express my sincere gratitude to my supervisors, Dr.Tran

discussion that will help reader to understand the insight of the research area The problem discussions end with a research problem and specific research question In the end of the first chapter we will also present the disposition of the thesis 1.1 Background of the study This section will provide the background of the research area This section contains some idea of e-commerce and online retailing as one of the important factor in e-commerce Also, a brief introduction of e-commerce situation in Cambodia is brought here This section also shows the importance of service quality and its relationship with customer satisfaction 1.1.1 E-commerce E-commerce has many definitions In business today electronic commerce is one of the common topics of discussion (Daniel, Wilson & Myers 2002) Is not very far from what TawfikJelassi& Albrecht Enders in 2005 believed is “Electronic commerce deals with the facilitation of transactions and selling of products and services online, i.e via the Internet or any other telecommunications network".This was an academic definition for e-commerce, what practitioners believe is: "Ecommerce is often referred to as e-business In order to perform one or more of the business functions Internet based e-commerce systems use World Wide Web based application solutions These business functions include information provision, communication, buying, selling, Stt.010.Mssv.BKD002ac.email.ninhd

and services online and provide a range of services that customers themselves can perform without direct human assistance Its allows customers to conduct a wide range of activities such as changing address, securing a credit card or loan, learning from other customers, personalizing a service agreement and purchases without human assistance (Molla and Licker 2001) Electronic commerce is a new way of conducting, managing and executing business transactions using computer (Kalakota and Whinston 1996) 1.1.2 Online Retailing The rapid growth of the electronics retailers worldwide as we have known today Although B2B plays a larger role in part of electronic commerce rather than B2C, both of them go pass the bricks and mortar Even if online visitors, most of them just try to search more informationinstead of buying These sites are e-CRM (customer relationship management) necessary tools for retailers to survive in a competitive market, value added services are necessary to keep the difference with their competitor After the emergence of many e-commerce companies start up the website to the pioneers in this field, but in the mid-2000 many bubbles burst The story of the surviving company will lead us to a better understanding of the strengths and powers.Customers are the lifeblood of an organization, so their satisfaction is the primary goal of the company 1.1.3 E-commerce in Cambodia In Cambodia the Internet is mainly used in the universities for research purposes, the internet stations throughout the cities are used for limited activities such as checkinge-mail and making long distance phone calls Thus the entryof electronic commerce in Cambodia is in its early stages Clearly, E-commerce is something new for this country, but it’s expected to grow steadily in the near future Stt.010.Mssv.BKD002ac.email.ninhd

studying the trend of online retailers which have gone away, we will be in a better position to establish policies and strategies of us Many studies have been done in the field of online retailers worldwide, while many retailers start their website, it is time to guide them appropriately Academician who takes the localization of foreign results to help companyachieving the world standards in Cambodia Here is some of the Cambodian online retailers which is starting their first step: www.bongthom.com, www.sombok.com.kh, etc 1.2 Problem Discussion Though the internet channel is increasingly being used by many online stores, but many online retailers are closed In the needs of a competitive market place understanding customer’s needs become very important So the company has moved from a central product to a central location of the customer Customer retention is directly affected by customer satisfaction Retention is an essential challenge, particularly in Internet-based services, as customers can easily switch from one service provider to another at low cost (Khalifa and Liu, 2003) Is not very far from Van Riel, Lijander&Jurriensin 2001which believe that “Considering the high costs of acquiring new customers and the apparently high customer turnover of many online services, it is very important to study the determinants of customer satisfaction” Customer satisfaction is the key factor determining how successful the organization will be in customer relationships, so it is very important to measure it Total quality management (TQM) is based on the idea of customer satisfaction - an approach to management of an organization focused on quality, based on the participation of all members and towards its long-term success through customer satisfaction and benefits to all members of the organization and to society (ISO Stt.010.Mssv.BKD002ac.email.ninhd

absolute value of the regression coefficients are standardized What elements have absolute value becomes larger, affecting as much satisfaction Therefore, in this model we see the customer satisfaction affects most from the response factors: Assurance (ASS) = 0.263; Reliability (REL) = 0.265; Responsiveness (RES) = 0.229; Empathy (EMP) = 0.168 Overall this analysis result shows what are the most powerful factor to the customer satisfaction Since then, marketer, company providing online services, especially the advertising company should have an idea to concern these affected factors This is the basis for building a number of measures to improve the efficiency of the selection of ideas, design and construction of more online services and quality to satisfy the increasing demand

by the emergence of Internet and Web technology Hence, it is not easy for break-and-mortar or online retailers to gain and sustain competitive advantages based only on a cost strategy in retailing market Rather, defining customers’ needs and preferences, and their related quality dimensions have increasingly become a key driving force in enhancing customers’ satisfaction and attract more customers Identification and ranking of customers’ expectations of the online retailer services provide a frame of reference for ranking customers’ preferences of service quality This study ranks28 factors of service quality based on Cambodian’s perspective Obviously, in order to maintain a high level of overall service quality, online retailers should pay attention to all these dimensions brought in this study include: Assurance, Reliability, Responsiveness, Empathy and Tangible, given by responders However, to strengthen competitiveness in the extremely competitive market, given limited organizational resources, it is recommended that online retailers should focus on the main five key dimensions, Assurance; Reliability; Responsiveness; Empathy; and tangibles (in which Tangible factor seem to be not very important) in order to achieve high level of service quality and customer satisfaction simultaneously More specifically, the following implications are recommended to onlineretailers: First and foremost, speed of access to the web site may be the critical determinant of the success of the online retailers Since the access to the Internet is not so fast in Cambodia, online visitors prefer to connect to those websites which could be opened easier and faster Therefore, to satisfy the customers, online Stt.010.Mssv.BKD002ac.email.ninhd

website plays a big role here, as the number of clicks for achieving the desired information depends on the design of the website Hence, it is important for managers to consider the different ways of reaching specific information on the website Second, 24 hours user accessibility factor indicate that websites are expected to be available all the time and all the days of the week Managers should insist on reputation of website and try to avoid the non-responding situations If anything happened that made the website down for a while; relevant information about the problem and the time it would be backed should be provided Third, assurance dimension implies that customers should be aware of privacy limits and security policies Managers should allocate specific space for introducing protection and privacy policies that are accessible for customers and give a thorough understanding about the way website is kept secure 5.2 Implications for Theory The main purpose of the study is to findwhich the online service quality dimensions impact on Cambodian customers’ perspective in online retailing sector and aim to rank what are the order of Service Quality dimensions that impact on Cambodiancustomers’ perspective in online retailing sector Theoretically, this study extends the knowledge body of service quality and customer satisfaction by enriching the Cambodian’s preferences in online retailing sector, and based on existing theories, this study tested five key service quality dimensions in online retailing context More specifically, concerning research question one the majority of the findings for this study supported the existing literature The new findings were discovered from quantitative empirical data.It also increased and enhanced understanding about relative importance service quality dimensions Stt.010.Mssv.BKD002ac.email.ninhd

explored In addition, the limitation and shortcoming of this study also provide implications for future research Future research could add extensions to this study This research needs further analysis While this research yields a number ofvery interesting results, we believe that there are a number of things that should be done to confirm our results as well as to expand our hypotheses Firstly, with the number of Internet users now over 45 thousand, a small group of online users in Phnom Penh, Cambodia is not enough Hence, research with larger samples that pose the same or similar questions would be appropriate Secondly, various languages, religions, cultures and a host of other factors may be important to user's impression of the quality of a web site At the end, in this competitive market, service quality is one of the key elements which bring value added for companies Online retailers are focusing on making their websites more appealing in order to increase their stickiness Practitioners need to understand the factors that make people to visit a website; spend some time and make them purchase online Researchers all around the world are talking about "loyal customers": they spread the good word-of-mouth, not to shift to competitor easily, spend more money and are cheaper to attract Practitioners should be aware of all factors which are affecting the behavior of their customers Respecting this critical issue for e-business, we believe more studies are needed to fulfill our e-world with superior facilities and make life easier and better
