TIEU LUAN MOI download : skknchat@gmail.com Loyalty of Internet customers in Vietnam -6 Hanoi Telecom, VTC, G-Tel, Vishiped and CMC TI in which three of the leading companies: VDC/VNPT, Viettel, FPT have obtained more than 85 percent of total Internet service market share in Vietnam As a result, ISPs must try their best to develop their marketing strategy and improve their business performance to increase their level of competitiveness From the above statistics, we can understand that the competition of Internet services in Vietnam is a severe war among three big ISPs: VDC/VNPT, Viettel and FPT Beside the diversification of services, enhancing the customer satisfaction and customer loyalty is considered to be the most effective way to compete in the market, especially in telecommunication industry which is on the verge of saturation point in some years’ time Customer loyalty are believed to be the most effective weapons for providers to complete with other rivals because these factors are the primary variables that impact customers’ intention to stay with their current providers (Khatibi, Ismail & Thyagarajan, 2002) The providers which satisfy customers can expect higher market shares and greater profitability and, in turn, encourage their customers to become loyal (Khatibi, Ismail & Thyagarajan, 2002) Aaker (1991) has discussed the role of loyalty in the brand equity process and has specifically noted that brand loyalty leads to certain marketing advantages such as reduced marketing costs, more new customers and greater trade leverage Expanding loyal customers can assist in generating a business’s profitability because the cost of retaining existing customers is less than that of acquiring new ones (Reichheld, Teal, 1996) Therefore, understanding how and why a sense of loyalty develops in customers remains one of the crucial management issues of our day By assessing the Internet service users in Ho Chi Minh city, this research will give useful information of a range of factors impact on Vietnamese internet users’ perceptions of their current ISPs, from which factors effecting customer loyalty, especially in telecommunication sector, will be derived In other words, this research provides ISPs the direction and valuable understandings of what factors should be taken into account to become successful -
