将环境污染视为非期望产出,并考虑省级区域的异质性,构建基于共同前沿的生态效率测度模型,对2005—2016年中国30个省市自治区的生态效率进行评价,并分析全国、三大经济带内及三大经济带间的差异。结果表明:考察期内中国整体生态效率偏低,但呈现平稳上升的趋势;在不同前沿面下,中国大多省市自治区生态效率的表现差异巨大;区域生态效率表现不同,东部地区生态效率最高、中部次之、西部地区最低,这与三大经济带的经济发展水平相一致;中国整体生态效率差距正逐步缩小,并趋向收敛,东部区域差距先收敛后发散但差距较小,中部区域差距趋向发散,西部区域差距居高不下,东部与中部间差距先收敛后发散且发散趋势明显,东西、中西部差距一直很大。 |

Abstract: |
Regarding the environmental pollution as the undesirable output and considering the heterogeneity of provincial region, this paper constructs the eco-efficiency measure model based on the common frontier to evaluate the eco-efficiency of 30 provinces in China in 2005—2016 and analyze its differential convergence. The results show that the overall ecological efficiency of China is low, but is growing steadily. Under different frontier, there are great differences in the performance of ecological efficiency in most provinces and cities. The regional ecological efficiency preforms in different trends. The ecological efficiency of the eastern region is the highest, the central region is the second, and the western region is the lowest. This is consistent with the level of economic development of the three economic zones. China 's overall ecological efficiency gap is gradually narrowing, and tends to converge. The gap among the eastern region tends to converge firstly and then to diverge, but the gap is smaller. The gap among the central region tends to diverge, and the gap among the western regions remains high. Still another, the gap between the east and the central region tends to converge firstly and then to diverge with very obvious trend. The gap between the east region and west region and the gap between central regions and western region have been remaining high. |
