| 摘 要： | 使用34个国家105家运营商1999～2004的季度面板数据,通过利润率分析法检验了移动通信行业的规模经济性,结果表明移动通信行业的用户规模与利润率之间存在倒U型关系,规模经济性只在一定范围内存在,过大的规模反而会降低利润率。同时根据估计参数给出了最优经济规模。

| Abstract: | In order to estimate the scale economies of mobile telecommunication,this paper analyzes the relationship between subscriber scale and profit rate by using data of 105 mobile operators from 34 countries from 1999 to 2004. Result shows that there is a U shaped relationship between subscriber scale and profit rate,the optimum scale is also be calculated through the parameter. |
