中国八大区域绿色经济效率的差异与空间影响机制

Differences and Spatial Influence Mechanism of Green Economic Efficiency between China's Eight Regions

引入非合意产出超效率SBM模型,测算了1991-2013年中国省际绿色经济效率,进而引入空间面板模型,研究了八大区域绿色经济效率空间影响机制,结论如下:考虑资源与环境后,中国经济效率水平有所下降;南部和东部沿海绿色效率水平最高,北部沿海、东北、长江中游次之,黄河中游、西南和大西北极低,大西北最低且不断下降;除了北部和东部沿海,各区域绿色效率均呈下降趋势;绿色效率有显著的空间正相关性,呈现局部集聚特征,且与人均GDP之间存在U型关系,FDI作用显著为正,教育投资、产业结构、禀赋结构作用为负,绿色效率的影响因素存在区域差异。

This paper introduces the Supper Efficiency Slack-Based Measure Model including undesirable output to calculate the green economic efficiency of China＇s provinces from 1991 to 2013 and then introduces spatial lag model and spatial error model of panel data to study spatial influence mechanism of green economic efficiency between China＇s eight regions. Findings are as follows. The economic efficiency of China declines under the dual constraints of energy and environment. The green efficiency of the southern coastal and eastern coastal is the highest,while the northern coastal,northeast and mid-yangtze take second place. On the other hand,the green efficiency of the mid-yellow,the southwest and the northwest is extremely low,especially the northwest is not only lowest but also declining. Moreover,the green efficiency of all regions is on the decline except the northern coastal and eastern coastal. The green efficiency has a significantly positive spatial correlation and shows local spatial agglomeration. Then the shape of the curve between per capita GDP and green efficiency is U-type,FDI has a positive effect on green efficiency while education investment,industrial structure and the structure of endowment have a negative effect. Finally,the influence factors of green efficiency are different between eight regions.
