【摘要】：随着环境污染问题日益严重和人们环保意识的不断提升，近年来我国对环境污染治理投入逐年增加。作为解决环境问题的重要手段之一——环保投资越来越受到重视。然而，我国的环保投资面临着规模不足、结构不合理以及投融资渠道单一等现状，在这样的背景下环保投资对环境的影响到底是怎样的？本文将针对这一问题进行深入的研究与分析，并在此基础上，进一步对环保投资的减排绩效水平进行评价，以期深入地了解我国环保投资的环境效应。在分析了我国环境污染与环保投资现状的基础上，本论文研究了环保投资的环境效应影响机理与渠道，系统地揭示了环保投资通过规模、结构以及技术水平三个渠道来发挥污染物减排、改善环境质量的作用机理。本文以工业“三废”为研究对象，选取2004-2010年我国30个省市的面板数据，并采用系统广义矩估计法（System Generalized Method of Moments）实证了环保投资对污染物排放的动态影响，实证结果表明我国环保投资的环境效应为正，但作用有限且具有一定的滞后性。在工业“三废”的指标中，经济增长与环境污染关系并不完全符合库兹涅兹倒U型曲线。第二产业比重的增加会加剧环境污染，而技术进步和FDI有助于我国污染物的减排。为了进一步深入研究环保投资的环境效应，本文借鉴投入产出的思路，将环保投资作为投入，污染物减排作为产出，并运用超效率DEA方法（Super—Efficiency DEA）对我国不同区域环保投资的绩效水平进行了测算，研究结果表明东部地区的环保投资绩效均值最高，其次是西部区域，，中部区域排名第三，东北区域居尾。针对这一现象，本文对环保投资绩效的区域差异性进行了分析并得出如下结论：东部区域环保投资绩效水平高可能与其经济实力强、环保投入大、民众环保意识相对较强有关；西部区域由于工业相对落后，污染较少，自然生态环境保护完善，所以有限的环保投资就可以取得较好的投资绩效；而中部区域和东北区域由于工业污染强度大，历史投资欠账较多，污染治理难度大，因此环保投资的绩效水平较低。最后本文根据我国环境污染及治理的现实情况，对如何进一步提高环保投资绩效以及充分发挥环保投资的环境效应给出了相关政策建议。
[Abstract]:With the increasingly serious problem of environmental pollution and the increasing awareness of environmental protection, our country's investment in environmental pollution control has increased year by year in recent years.As an important means to solve environmental problems, environmental protection investment has been paid more and more attention.However, environmental protection investment in our country is faced with insufficient scale, unreasonable structure and single investment and financing channels. What is the impact of environmental protection investment on the environment under such a background?On the basis of this, this paper will further evaluate the emission reduction performance of environmental protection investment in order to understand the environmental impact of environmental protection investment in China.Based on the analysis of the current situation of environmental pollution and environmental protection investment in China, this paper studies the mechanism and channels of environmental protection investment, and systematically reveals the scale of environmental protection investment.Structure and technical level of three channels to play a pollutant emission reduction, improve the environmental quality of the mechanism.In this paper, the panel data of 30 provinces and cities in China from 2004 to 2010 are selected, and the system Generalized Method of moment estimation method is used to demonstrate the dynamic impact of environmental protection investment on pollutant emissions.The empirical results show that the environmental effect of environmental protection investment in China is positive, but the effect is limited and has a certain lag.In the index of industrial "three wastes", the relationship between economic growth and environmental pollution does not completely accord with Kuznets inverted U-shaped curve.The increase of secondary industry proportion will aggravate environmental pollution, while technological progress and FDI will contribute to the emission reduction of pollutants in China.In order to further study the environmental effects of environmental protection investment, this paper uses the idea of input-output for reference, taking environmental protection investment as input and pollutant emission reduction as output.The performance level of environmental protection investment in different regions of China is measured by Super-Efficiency DEAA. The results show that the average performance of environmental protection investment in the eastern region is the highest, followed by the western region, and the central region ranks third.The northeast region is the end of the region.In view of this phenomenon, this paper analyzes the regional differences of environmental protection investment performance and draws the following conclusions: the high performance level of environmental protection investment in the eastern region may be related to its strong economic strength, large investment in environmental protection, and relatively strong public awareness of environmental protection;Due to the industrial backwardness, less pollution and perfect protection of natural ecological environment in the western region, the limited investment in environmental protection can achieve better investment performance, while in the central region and the northeast region, the intensity of industrial pollution is high.The history investment is short of debt, the pollution control difficulty is big, therefore the environmental protection investment performance level is low.Finally, according to the actual situation of environmental pollution and control in China, this paper gives some policy suggestions on how to further improve the performance of environmental protection investment and give full play to the environmental effect of environmental protection investment.
