转型期自然垄断产业民营化进程与全要素生产率的变动——以中国电力产业为例

The Progress of Privatization and Changes of TFP in Natural Monopoly Industries during the Transition Period: A Case of China’s Electricity Industry

在运用索洛余值法对1987-2007年间中国电力产业全要素生产率测算的基础上,建立包括电力产业民营化进程、政府定价、电源结构、资本深化等TFP影响因素的回归模型进行实证分析。结果发现,随着电力产业民营化进程的深入(即国有经济所占比重下降),电力产业的全要素生产率不断得到提高。同时,实证分析还表明政府价格规制对电力产业全要素生产率影响不显著,电源结构不合理则明显制约了全要素生产率的提高。

On the basis of the measurement of the TFP of China＇s electricity industry during 1987-2007 with Solow Residual method, this paper establishes a regression model to make an empirical analysis of such TFP influencing factors as privatization of power industry, government fixed price, power structure, deepening of capital and so on. The results indicate that with the deepening of the privatization in the power industry （i.e. the decreasing proportion of state-owned economy）, the TFP of the power industry is improving. Meanwhile, the empirical study also shows that the price regulation by the government has little effect on the TFP of the power industry; however, the unreasonable structure of power resources obviously restricts the improvement of TFP.
