区域能源消费与经济和环境绩效——基于14个能源输出和输入大省的实证研究

The economic and environmental performance of regional energy consumption:An empirical study on 14 major energy output and input provinces in China

本文对中国的能源输出大省和能源输入大省进行了界定,运用DEA方法测度了2000-2010年能源输出和输入大省的能源消费经济绩效、环境绩效及节能潜力,对能源输出和输入大省的能源消费经济绩效、环境绩效特征进行系统归纳和比较,分析能源消费绩效形成原因,并利用Malmquist生产率指数方法对2000-2010年能源输出和输入大省的能源消费经济绩效、环境绩效变化趋势进行了深入研究,探讨提高能源输出和输入大省能源消费绩效的对策措施。研究结果表明:1能源输出大省的能源消费绩效未达最优主要受规模效率制约,规模效率和纯技术效率对能源输入大省能源消费绩效未达最优的共同制约比较明显;2能源输出大省的整体能源消费经济绩效改善落后于能源输入大省,但在环境绩效改善方面能源输出大省整体上强于能源输入大省;3技术进步是决定能源输出和输入大省能源消费绩效变化趋势的关键;4半数能源输出大省和大部分能源输入大省存在投入冗余现象,基于环境产出投入冗余远高于基于经济产出投入冗余,尤其是能源输入大省。

This paper defines energy output and input provinces in China, and adopts DEA method to measure economic and environmental performance of energy consumption and energy saving potential for the energy output and input provinces from 2000 to 2010. The causes and characteristics of energy consumption performance are analyzed. The energy consumption performance of energy output provinces is compared with that of energy input provinces. Then, this paper uses the Malmquist index model to examine the changing trend of economic and environmental performance of energy consumption for the energy output and input provinces from 2000 to 2010. Finally, we discuss the strategies for promoting energy consumption performance of energy output and input provinces. The results show that, energy output provinces failing to reach optimal energy consumption performance are mainly restricted by scale efficiency, while energy input provinces are restricted by scale efficiency and pure technological efficiency. Energy consumption economic performance improvement of energy output provinces lags behind that of energy input provinces, but energy consumption environmental performance improvement of energy output provinces is better than that of energy input provinces. Technological progress is key to a changing trend of energy consumption performance. Half of the energy output provinces and most of the energy input provinces have input redundancy, and the input redundancy based on environmental output is much higher than that based on economic output, especially for the energy input provinces.
