| 6. Conclusion
So far, in Vietnam, market share (by revenue and by subscription) is the only parameter that determines the dominant position of a market player and is the basis for any regulation form to be taken. However, the market share(s) of one or some large firms does not fully reflect the concentration of the market nor does it show how much power the firm can release to change market prices to earn surplus profit. This article uses common international indicators and measures to assess the level of market concentration and competition for Vietnam mobile telecommunications market. The two indicators calculated are the HHI and the elasticity of the demand, which allow a comparison of the competition position of the Vietnam mobile market against other countries. The two indicators also help the interpretation of the market characteristics as well as provide some implications about the price and demand trend in the mobile telecommunications market of Vietnam. These are also important indicators for regulators to refer to before introducing any specific regulation. The article has certain limitations, mainly related to collected data. Firstly, when determining the HHI, the article bases on the subscription market share, but HHI should be calculated also based on the revenue market share which is the benefit indicator associated with the business. Second, the data of demand, price and other variables for price elasticity of demand estimation were collected from various sources (Ministry of Information and Communications, Vietnam Government Statistics Organization, ITU, business reports). Data from these sources sometimes are not consistent affecting the estimation results. The length of the time series date is also short. Third, research has not yet collected data to calculate the elasticity of demand for mobile telecommunications services of each network operator. This estimation would indicate the market power of each firm in the market, so that the picture of concentration and competition in the mobile telecommunications market will be clearer. In the future, the article could overcome the disadvantages by either trying to collect firm- specific data from different competitors in the market, or through a different approach using primary data by survey to determine the demand function model of the market. tải về 274.4 Kb.
