长江中游城市群能源效率评价研究
Study on energy efficiency in the middle reaches of the Yangtze River city group
摘要
Abstract
Improving energy efficiency and promoting the transformation of low-carbon economy are the key and difficult point of the current regional coordinated development and new urbanization construction in the middle reaches of the Yangtze River city group.Based on the meta-frontier theory, the non-parametric frontier was constructed by using the data envelopment analysis method and sulfur dioxide emissions, the undesirable output, were incorporated into the DEA model.This paper compared and analyzed the regional differences in total-factor energy efficiency in the middle reaches of the Yangtze River city group and technology gap ratio was used to measure the technology gap of energy utilization among the three regions.On the basis of this, the decomposition of energy inefficiency and the correlation analysis of the actual energy intensity and the potential energy intensity were studied.The results showed that: ①At present, the overall level of total-factor energy efficiency in the middle reaches of the Yangtze River city group was low, but the regional differences were not significant.②The technology gap of energy utilization among the three regions was not great.③Effects of technology gap and management factors on energy inefficiency of different regions were different.④Both the actual energy intensity and the potential energy intensity were in a certain downward trend, and the gap between the two was gradually narrowing.Finally, some conclusions were drawn, adhering to the principle of 'seek common ground while reserving differences' in the development of regional energy-saving strategy, accelerating technological progress, carrying out energy technology innovation actively and improving the level of management constantly.At the same time, the government should provide more policy support to the middle reaches of the Yangtze River city group, so as to fully explore the potential of energy-saving and emissions reduction in the middle reaches of the Yangtze River city group, which is significant to enhance the overall level of China's regional energy efficiency and promote the transformation of green economy.关键词
