省域异质性视角下中国能源绩效的测算与分析

Estimation and analysis on energy performance of China based on provincial heterogeneity perspective

文中从能源节约和省域异质性的视角出发,运用固定效应随机前沿分析的参数方法测算了中国省域动态能源绩效指数,并分解为技术进步指数与技术效率变化指数。研究表明:考虑省域异质性后,各省市的能源技术效率在时间和空间上的差异减小,节能技术进步是推动能源绩效持续增长的主要因素;中国东部地区技术进步效应突出,推动能源绩效持续增长,中部地区以更低的速度获得能源绩效的持续改善,而西部地区能源绩效并没有明显改善趋势;东部、中部和西部地区的能源绩效增长速度均呈U型演变态势。推动节能技术的进步和创新,才能有效缓解中国能源供给缺口与经济发展的矛盾,强化中国能源治理能力。

Based on the perspective of energy conservation and heterogeneity,we used the fixed-effects stochastic frontier model to measure the performance of Chinese provincial energy consume,and then decomposed it into effect of technical progress and efficiency improvement. The main findings are as follows. The differences of energy efficiency in time and space was reduced after considering provincial heterogeneity,energy-saving technology progress was the main factor promoting the growth of energy performance. In eastern of China,technological progress effect was outstanding,which promoted the growing of energy performance; the central region was at a lower speed,and in the western region,there was no significant trend of improvement. in eastern,central and western region the energy was in U evolution trend for the growth performance. Promoting energy-saving technology innovation can effectively remit the contradiction between China＇s energy supply gap and economic development,and strengthening China＇s energy management ability.
