本文基于2005—2012年全国29省区火电行业面板数据,运用超越对数形式的随机前沿分析方法,对中国火电行业技术效率进行实证分析。研究结果表明,中国火电行业平均技术效率水平不高,介于0.804—0.872之间,波动较为明显,且地域差异较大。在技术效率影响因素的分析中,经济发展水平虽然显著,但影响力度微弱;发电设备利用率、环境规制强度和煤质与火电无效率显著负相关;电厂自用电率与火电无效率显著正相关。并据此提出了相应的政策建议。
Based on the panel data of 29 provinces and autonomous regions in China from 2005 to 2012, this paper uses the stochastic frontier analysis method which exceeds the logarithmic form to make an empirical analysis of the technical efficiency of China’s thermal power industry. The results show that the average level of technical efficiency of China’s thermal power industry is not high, ranging from 0.804 to 0.872, with obvious fluctuations and large geographical differences. In the analysis of the influencing factors of technical efficiency, although the level of economic development is significant, the influence is weak; the utilization ratio of power generation equipment, the strength of environmental regulation and the inefficiency of coal quality are negatively and significantly negatively correlated with the inefficiency of thermal power; Related. And accordingly put forward the corresponding policy recommendations.
