【摘要】 自1978年改革开放以来,我国经济社会高速发展是不争的事实,然而这种发展是以资源消耗、环境破坏为代价的粗放型经济增长,由此带来了较为严重的环境问题。同时,由于地域条件限制和改革开放先后次序等原因,经济发展水平和环境问题的地区状况差异巨大。环境问题引起了社会各界的高度关注,国内外学者从不同角度做了大量研究。鉴于各地区经济发展所处的阶段不同,面临的主要环境问题和严重程度也有所差异,本文在考虑环境变量的基础上,从投入产出的角度对地区间的环境效率进行研究。数据包络模型由于其在处理多投入产出变量问题上的显著优势,在该类研究中占有重要地位。针对利用基本方法在研究国内环境质量过程中对经济生产活动描述脱节的问题,本文首先梳理了数据包络模型的基本方法和一些具有代表性的模型在环境问题研究中的运用;然后,分析了基本模型在评价环境效率过程中所存在的问题,在此基础上对变量的可处置性质、效率测度方式和效率参数设置等方面进行了探讨,并根据投入产出变量属性、变量的数值特征差异以及相互间关联关系,利用可处置性质和效率参数对基本模型进行了改进;然后运用改进后方法对我国2008~2012年各省域经济的环境效率作有效性评价,并以2012年的评价结果作为样本,对比总结环境效率基本模型与改进后模型在评估效果上特征及其差异性。研究结果表明,出现较高水平环境效率的省域主要集中在经济发达的沿海以及发展水平相对滞后的地区,有东高西低的趋势,且各省份的环境效率存在一定的惯性;不同模型测度环境效率时存在差异,应根据需要选取;而与基本方法结果的对比显示,改进后的模型对样本的鉴别能力更好,省域环境效率值对比更明显,体现了部分模型的一些特征,综合性更好。基于以上研究,最后总结了本文研究的内容和结论,并给出了相应政策建议。
【Abstract】 Since the reform and opening up from 1978, China’s rapid economic and social growth is an indisputable fact, however, the extensive economic growth is at the expense of resource consumption and environmental destruction, which has resulted in a series of serious environmental problems. At the same time, due to geographical constraints and priorities of reform and opening up, also other reasons, regional economy development and environmental issues differ significantly. Environmental issues have aroused great concern in various circles of society, so domestic and foreign scholars have done a lot of research in different respects. Given the diverse stages of economic development of the distinct part of China, the main environmental issues and the severity they face are not the same. Based on the foundation of considering environmental variables as input and output problem, research on provincial environment efficiency is carried out.Due to the significant advantage in handling multiple input and output problems, Data Envelopment Model plays an important role in such research. In view of that gap between the description of economic activities and real ones should be bridged, when the basic Data Envelopment Model is used to research domestic environmental quality, the basic theory of Data Envelopment Model and number of representative models used in the study of environmental issues are reviewed in this paper; Then problems existing in the traditional model are analyzed, and the disposability of variables, ways to measure the efficiency, parameter settings, etc, are discussed, which are used to improve the basic model, in accordance with the input-output variable attributes and differences of variable value characteristic, and mutual relationship between them are also taken into consideration. Then the improved environment efficiency model is used to evaluate provincial environment efficiency from 2008 to 2012, and with evaluation results of 2012 as sample, their assessment effect difference is compared between the basic environment efficiency models and the improved one, at the same time, their characteristics are summarized.The results of the study show that higher levels of provincial environmental efficiency appear mainly in the developed coastal areas as well as the places which are lagging behind, and there is a trend that environment efficiency declines from the east to the west, and the environmental efficiency of each province shows a certain inertia; The measurement differs for different models, so model selection should be based on requirement; Comparing the results with the basic approach, the improved model identify the samples better, and comparison of provincial environmental efficiency values comes out to be more obvious; And the improved model reflects some features of other models, and has better integration. Finally, the content and conclusions of this study are given based on these researches, and corresponding policy recommendations are also offered.
