| 基于新古典经济增长理论，构建了区域生态效率空间收敛分析的理论框架。利用2004-2015年的我国省际面板数据，运用超效率DEA模型测算了各省的生态效率，分析了区域生态效率的区间差异，然后利用空间滞后模型讨论了β收敛情况。结果显示：1）区域生态效率逐年改善，区域差异明显，但大部分区域的差距在缩小；2）全国和东中西部地区均不存在σ收敛，考虑空间互相关下，全国和东中西部地区均存在β收敛，收敛速度呈现东部最快、中部次之、西部最慢的格局；3）在引入城镇化等控制变量后，β条件收敛速度上升，东部和西部尤为明显；4）城镇化和市场化促进了生态效率提升，产业结构优化给生态环境带来了压力。因此，提升区域生态效率收敛依赖于新型城镇化建设的进程、市场化改革的程度和产业结构优化的落实。 |

| Abstract: |
| Based on the theory of neoclassical economic growth, this study constructs a theoretical framework of the spatial convergence analysis of the provincial regional Eco-efficiency. Using the provincial panel data from 2004 to 2015 in China, the provincial ecological efficiency by super efficiency DEA model is measured, and the regional differences of ecological efficiency is analyzed, then the convergence condition of beta through the spatial lag model is tested. The results show that:1) The regional ecological efficiency has been improved year by year and regional difference is obvious, but the differences in most regions are narrowing. 2) There is no convergence in the east area, the middle area, the west area, even the whole country. 3) Considering the spatial cross-correlation, there is β convergence in each area and the whole country. The convergence rate of β is the fastest in the east, the second in the middle and the slowest in the west. However, after introducing some control variables such as urbanization, the convergence rate of β conditions increases, especially in the east and west. 4) Urbanization and marketization promote the improvement of ecological efficiency, and the optimization of industrial structure brings stress to the ecological environment. In conclusion, the improvement of the convergence of ecological efficiency in the region depends on the process of new urbanization construction, the degree of market-oriented reform and the implementation of industrial structure optimization. |
