我国碳排放效率的区域动态差异、敛散性及时变因素分析

Analysis on Regional Dynamic Difference,Convergence and Time-varying Influencing Factors of Carbon Emission Efficiency

把碳排放作为投入要素,依托投入导向的DEA模型,采用分省1996—2011年的相关数据,测算中国大陆26个省份碳排放效率。利用绝对β收敛理论检验了全国及东、中、西部地区碳排放效率的敛散性。从时间和空间两个维度考察了单位地区生产总值能耗、能源消费结构、经济发展水平、产业结构、外贸依存度、外资强度和所有制结构对碳排放效率的影响。碳排放效率在全国和东部地区存在绝对β收敛,而中部和西部地区则有发散的趋势。从时间上来看,影响碳排放效率的主要因素为外贸依存度、经济发展水平和单位地区生产总值能耗;从空间上来看,影响碳排放效率的主要因素为经济发展水平、外贸依存度和所有制结构。

From the elements of perspective in carbon dioxide emissions, relying on input-oriented DEA mod- el, using our provincial data from 1996 to 2011, this paper calculates carbon emission efficiency of 26 provinces, tests the national and eastern, western, central convergence and divergence of carbon emission efficiency using ab- solute beta convergence theory. The national and eastern is existing absolute beta convergence, but not western and central. From the point of time, the dependence on foreign trade, the level of economic development and the ener- gy consumption of unit GDP are the important factors that influence carbon emission efficiency; from the point of space, the important factors that influence carbon emission efficiency are the level of economic development, the dependence on foreign trade and ownership structure.
