基于方向性距离函数的中国省区二氧化碳排放绩效研究

Research on Carbon Dioxide Emissions Performance of Chinese Provinces Based on Directional Distance Function

摘要:

利用基于方向性距离函数的DEA方法测算了中国30个省区2007年～2011年的二氧化碳排放绩效,并分析了其影响因素。研究发现：我国省区二氧化碳排放绩效年均增长0.1%,这主要来源于技术效率的改善,而较多省区则出现了技术边界 “内陷”的现象；我国省际二氧化碳排放绩效差异较大,其中东部和东北省区的二氧化碳排放绩效较高,而中西部省区则较低,这主要是由技术进步的省际差异所致；通过二氧化碳排放绩效影响因素的分析发现,能源强度对二氧化碳排放绩效的提高具有抑制作用,经济发展、产业结构优化以及对外开放对其具有显著的促进作用,而市场化程度的影响则不明显。

Abstract:

By using the DEA method based on directional distance function,the paper evaluates carbon dioxide emissions performance of Chinese 30 provinces during 2007-2011, and analyzes its influencing factors.The main results show that carbon dioxide emissions performance of Chinese provinces maintains a annual growth rate of 0.1%, which is caused by an improvement of technical efficiency, and more provinces take on technical boundary "invaginations" phenomenon;Carbon dioxide emissions performance difference of Chinese provinces is obvious, the eastern and northeastern provinces have a higher carbon dioxide emissions performance, while that of the central and western provinces is low, which is caused by regional differences of technical progress;The analysis of influencing factors of carbon dioxide emissions performance shows that carbon dioxide emissions performance can be inhibited by energy intensity, the level of economic development, industrial structure optimization and opening to the outside world have a significant promoting effect on it, but the effect of degree of marketization on it is not obvious.
