particular market. Taking the 30% market share as a threshold for the application of the prohibition provisions of Vietnam's Competition Law is explained that this benchmark is applied by many countries around the world. However, many studies have shown this to be the raw determinant of market dominant position in the telecommunications market [6]. The objective of this paper is to use internationally popular assessment methods to analyze market concentration and the existence of significant market power in the Vietnam’s mobile services market. This study, on the one hand, is practically an important reference for Vietnamese telecoms regulators, competition regulators as well as firms participating in the market. On the other hand, this study also adds to the empirical literature on the topic for comparative studies. This paper proceeds as follows. Section 2 is a brief review of empirical studies on market concentration and market competition. Section 3 presents an overview of the Vietnam’s mobile market as a basis for the analysis of sections 4 and 5. Section 4 includes the calculation results of the Hirschman-Herfindahl index (HHI) and the estimated model of price elasticity of demand in Vietnam mobile services market which are comparable to other relevant studies. Section 5 gives some discussion of the results obtained before a conclusion is given in the last section. 2. A brief review of literature In economics, market concentration is a function of the number of firms and their respective shares of the total production or sales in a market. It measures the extent of domination of production or sales by one or more firms in a particular market and is often used as a measure of competition. To evaluate market concentration and the existence of market dominating companies, researchers and regulatory bodies often derive from market shares. Enterprises with large market shares are more likely to control the prices and volumes of services provided in the market and thus gain higher returns. However, the market share only provides discrete information of each firm, so some aggregate indicators such as the C4 (4 firm concentration ratio) and Hirschman- Herfindahl (HHI) indices have been released.
