【摘要】 为研究转移成本对消费者行为和市场结构变化的影响,本文以移动通信市场为例,通过考察市场实际情况改进了纳什—伯川德模型,定量精确推算了双寡头垄断市场下的顾客转移成本。该模型通过引入价格补偿机制区分开新老用户,考虑了移动运营商通过对老用户的价格歧视攫取超额利润,并通过补偿新用户以争夺市场份额的现实。实证研究结果表明,双寡头垄断市场下的中国移动与中国联通在2002-2007年间的顾客转移成本逐年下降,且两者整体差距逐渐增大。通过对此期间的移动通信监管和市场竞争的分析,解释了转移成本变化对市场结构动态变化的影响,为进一步研究降低顾客转移成本以优化通信市场结构奠定了理论基础和实证支持。更多还原

【Abstract】 In order to study the impact of switching costs on the change of market construct,this thesis improves the Nash-Bertrand model according to the investigation on the real market,and precisely calculates the customer switching costs in the market monopolized by the two oligarchs,with mobile communication market as the case study. This model divides the new customers from the old ones by introducing the price compensation system,and considers the fact that the mobile operators snatch the super profit by discriminating the old customers in terms of price and compete for the market share by compensating the new customers.The empirical study indicates that the customer switching costs of China Mobile and China Unicom between 2002 to 2007 was decreasing year after year,and the gap between the two operators is gradually increasing.This thesis explains the influence of the changes in switching costs on in the market construct by analyzing the supervision on mobile communication and market competition in this period,and it lays the theoretical foundation and the experimental support for further studies on reducing the customer switching costs.更多还原
