文章摘要:基于系统论视角,将生态经济系统划分为生态、社会和经济三个子系统,并分析三者之间的作用机理。进一步,构建基于矩阵型结构的网络DEA模型对生态经济效率进行评价。利用该模型对我国省际2007—2012年的生态经济效率进行测算,并对其敛散性进行检验。实证结果显示:①整体、区域及省际生态经济效率处于低下水平,社会子系统和生态子系统是导致整体效率低下和区域差异的主要原因,且生态子系统尤为关键。②对比三大区域可知,在整体效率、经济效率和社会效率层面,东部地区最高,其次是中部、西部;在生态效率层面,西部最高,东部次之,中部最低。③生态经济整体效率和社会效率呈发散趋势,经济效率和生态效率呈现稳定状态。结合实证结果,提出了一系列政策建议。
Abstr:From the perspective of system theory, ecological economic system can be divided into economic subsystem,social subsystem and ecological subsystem. On the basis of the relationship among the three subsystems, a new matrixtype network DEA is built to evaluating the regional eco- efficiency. Not only does the model overcome the defect of traditional DEA models which ignore the internal structure of decision making units, but also the efficiencies of subsystems are given. Then, this paper evaluates the eco-efficiencies of Chinese provinces from 2007 to 2012, and it also examines the corresponding convergence test. The empirical results show that:(1) Overall, regional and provincial ecoefficiencies are at the low level, where social system and ecological system are the main resources of the overall inefficiency and regional differences, especially for the ecological subsystem.(2) Comparing the three regional ecoefficiencies, for the overall, economic, and social efficiencies, the eastern region is the highest, followed by the central and western regions; for the ecological efficiency, the western region is the highest, followed by the eastern and central regions.(3) The overall and social efficiencies keep a divergent state, while economic and ecological efficiencies are at the steady state. According to the empirical results, some useful policy implications are put forward.
