网络融合、技术进步与电信业生产率增长--基于中国31省市面板数据的实证研究

文章立足网络融合深化发展的现实背景，首先引入Herfindahl指数衡量中国电信业网络融合程度，然后采用Malmquist生产率指数方法测算了我国电信业的全要素生产力及其分解值变化情况，并通过构建多元面板回归模型，对网络融合、政府规制及其他影响因素进行了实证检验。研究结果表明：整体上，中国电信业全要素生产率实现了明显的增长，增长的源泉主要来自于技术进步。在影响因素方面，网络融合和行业重组改革对中国电信业的全要素生产率增长和技术进步均起到了积极的促进作用，价格上限规制政策则产生了明显的负面作用。此外，经济发展水平、人口密度、市场规模、电信业重要程度等宏观经济因素也从不同方面产生重要影响。

Network Convergence,Technical Progress and Productivity Growth in Telecommunications Industry-Empirical Analysis Based on Provincial Panel Data of China

The paper measures the degree of network convergence of Chinese telecommunications industry by Herfindahl index ,considering the development of network convergence .We calculate the telecommunications industry＆#39;s TFP and its decomposition value through Malmquist productivity index method .And we make an empirical test of the effects of network convergence ,government regulation ,and other factors by constructing a multivariate panel regression model .The results show that the overall TFP of Chinese telecommunications in-dustry has increased significantly ,w hich mainly comes from technical progress .In terms of influencing factors , network convergence and industry restructuring reform both play a positive role in Chinese telecommunications industry T FP grow th and technological progress ,but the regulation policy of price cap produces a significant negative effect .In addition ,there exist significant impacts from different aspects in the level of economic devel-opment ,population density ,market size ,degree of importance and other macroeconomic factors .
