中国区域经济增长效率与碳减排技术效率的测度——兼论其协调性

Measurement of China's Regional Economic Growth Efficiency and Carbon Emission Reduction Efficiency: with a View on Their Coordination

从环境经济学的角度,运用非径向方向性距离函数和TOPSIS分析方法构建了经济增长效率和碳减排技术效率及两个指标的协调度指标。基于中国1998-2010年29个省的数据进行了实证研究。结果表明,中国经济增长技术效率在总体上处于下降趋势,而碳减排技术效率相对于经济增长效率还存在较大差距,中国普遍存在碳减排滞后于经济增长的现象,但中国部分省份已经开始逐渐从碳减排严重滞后于经济增长转向碳减排与经济增长协调发展。该结果预示着中国正逐渐步入低碳发展的道路。

From the viewpoint of environmental economics, this paper establishes the index of coordination degree to describe the two indexes of economic growth efficiency and carbon emission re- duction efficiency with the non-radial directional distance function and the TOPSIS method. And then it conducts an empirical study based on the data from China＇s 29 provinces from 1998 to 2010. The results suggest that on the whole China＇s technical efficiency of economic growth has a downward tendency, while the efficiency of carbon emission reduction has a bigger gap with respect to the efficiency of economic growth. Such phenomenon exists widely in China that carbon emission reduction lags behind economic growth. However, some provinces have started to change from the situation that carbon emission lagging seriously behind economic growth into the coordinated development between economic growth and carbon emission reduction, which indicates that China is gradually stepping on the road of low carbon development.
