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 
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 
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.
