摘要:

环境问题已经成为辽宁省经济发展的瓶颈。基于随机前沿分析SFA与非期望产出的数据包络SBM的研究方法,选取2005年到2011年为研究时间,对辽宁省14个地级市环境效率进行测算,并利用聚类分析、基尼系数与β趋同等研究方法对环境效率进行时空分析。在此基础上,利用Tobit模型建立多元回归,以分析辽宁省环境效率的影响因素。结果表明:大连、沈阳、鞍山的环境绝对效率水平较高,朝阳市绝对效率水平最低;大连、盘锦、沈阳处于生产有效单元,朝阳相对效率属强无效单元;在空间与时间的分析上大连、沈阳等是效率水平高的地区,朝阳为最低地区,空间呈“山脊状”分布;绝对效率值差距在不断缩小,相对效率差距在拉大后趋于稳定;回归结果显示产业结构与经济发展水平对环境经济效率及企业资本深化与生产技术水平起正向作用;财政支持与外商直接投资没有通过模型检验,未对环境效率起作用。

Abstract:

Environment problem has become a bottleneck restricting the Liaoning economic development. Based on the research methods of stochastic frontier analysis and undesired output data envelopment analysis, for measuring the environmental efficiency of 14 prefecture-level city in Liaoning province, we selected the years of 2005 to 2011 as a research period, and did the spatiotemporal analysis of environmental efficiency, with the help of cluster analysis, the Gini coefficient and β convergence et cetera. On this basis, we established the multiple regression by using Tobit model, analyzing the impact elements of environmental efficiency in Liaoning. The results show that: the environment absolute efficiency of Dalian, Shenyang and Anshan is on the higher level, while Chaoyang is on the lowest level. Dalian, Panjin, and Shenyang are in the condition of effective production unit. Chaoyang's relative efficiency belongs to strong invalid unit. In the temporal and spatial analysis, Dalian and Shenyang are areas with high efficiency level, whereas Chaoyang is the area with the lowest efficiency level. The space is distributed as "mountain ridge"-shaped pattern. The gap of absolute efficiency value was constantly shrinking, meanwhile, the gap of relative efficiency has consequently stabilized after it is widened. The regression results show that the industrial structure and the level of economic development have positive effects on the environment economic efficiency, as well as on the capital deepening and production technical standard of enterprises. Financial support and foreign direct investment, which are not tested by the model, play no roles in environmental efficiency.
