【摘要】：要实现一个国家经济平稳较快的增长,不仅要保证经济数量上的增长,更重要的是经济质量方面的提升,即注重技术效率的快速平稳的提高。而一个地区的非期望产出对技术效率的测度影响很大,不考虑非期望产出会影响到环境技术效率测算结果的准确性。当前我国环境问题日益突出,已直接阻碍了我国经济发展的进程,因此全面的考虑环境污染因素能更好的把握和定位我国环境技术效率的整体水平,这对于提升我国环境技术效率有很大的帮助。本文结合我国现阶段的环境因素和环境技术效率的理论研究,从三个方面研究我国环境技术效率：首先,在环境技术效率评价模型框架下,运用随机边界模型中的柯布-道格拉斯距离函数,引入环境污染二氧化硫和二氧化碳排放量,测算我国各省环境技术效率值。结果表明我国环境技术效率水平存在明显的差异。2001-2010年期间全国平均环境技术效率的变化趋势是环境技术效率随着时间的推移而不断的增大,这说明我国的行业生产技术在不断进步,科学技术在不断创新,使我国的环境技术效率才有如此大的进步。其次,在环境约束条件下,分析了我国东、中、西部地区的环境技术效率差异情况,并且重点研究碳排放对我国三大区域环境技术效率的影响。从三大地区的环境技术效率水平差异分析,存在着明显的地区性差异。东部地区是我国环境效率水平最高的地区,中部其次,西部最后。我国三大地区出现阶梯式的变化,差异化非常明显,其原因与东、中、西部的经济发展水平、经济结构、所处的地理位置以及资源禀赋等因素有关。最后,将已测算出的环境技术效率作为被解释变量,选取五个影响因素,分别是人均GDP、产业结构、技术进步、进出口总额占GDP的比重以及污染治理投资,应用面板数据模型,对影响中国环境技术效率的因素进行实证分析,得出人均生产总值、技术进步、环境治理投资均呈现正相关关系,产业结构和对外贸易程度对环境技术效率呈现负相关影响,其中技术进步和对外开放程度不显著。基于上述研究,本文进一步分析了各地区环境技术效率差异的原因并提出改进的意见,建议我国在全面发展过程中要更加注重区域协调性发展。
[Abstract]:In order to achieve a country's steady and rapid economic growth, it is necessary not only to ensure economic growth in quantity, but also to improve the quality of the economy. That is, pay attention to the rapid and steady improvement of technical efficiency, and the non-expected output of a region has a great impact on the measurement of technical efficiency. Not considering the non-expected output will affect the accuracy of the environmental technical efficiency measurement results. At present, the environmental problems in China become increasingly prominent, which has directly hindered the process of economic development in China. Therefore, comprehensive consideration of environmental pollution factors can better grasp and locate the overall level of environmental technical efficiency in China. This is of great help to improve the efficiency of environmental technology in China. This paper studies the efficiency of environmental technology in China from three aspects, combining with the theoretical study of environmental factors and environmental technical efficiency at present in China. Firstly, in the framework of environmental technical efficiency evaluation model, using the Cobb-Douglas distance function in the stochastic boundary model, introduce environmental pollution sulfur dioxide and carbon dioxide emissions. The results show that there are obvious differences in the level of environmental technical efficiency in China. The change trend of the national average environmental technical efficiency in the period 2001-2010 is the environmental technical efficiency. Increase over time. This shows that China's industrial production technology is making continuous progress, science and technology are constantly innovating, so that China's environmental technology efficiency has made such great progress. Secondly, under the condition of environmental constraint, the difference of environmental technical efficiency in east, middle and west of China is analyzed. And focus on the impact of carbon emissions on the environmental technical efficiency of the three major regions of China. From the three regions of environmental technology efficiency level difference analysis. There are obvious regional differences. The eastern region is the region with the highest level of environmental efficiency in our country, the central region is the second, and the west is the last. The three major regions of China have stepped changes, the differentiation is very obvious, the reasons and the east. The level of economic development, economic structure, geographical location and resource endowment are related to the level of economic development in the middle and west of China. Finally, the calculated environmental technical efficiency is taken as the explained variable, and five influencing factors are selected, which are per capita GDP, industrial structure and technological progress. The proportion of import and export to GDP and the investment of pollution control are analyzed by using panel data model, and the factors that affect the efficiency of environmental technology in China are analyzed empirically, and the per capita GDP and technological progress are obtained. There is a positive correlation between the investment in environmental governance and the industrial structure and the degree of foreign trade. There is a negative correlation between the industrial structure and the degree of foreign trade, among which the technological progress and the degree of opening to the outside world are not significant. Based on the above research, this paper further analyzes the reasons for the differences of environmental technical efficiency in different regions and puts forward some suggestions for improvement. It is suggested that China should pay more attention to the coordinated development of regions in the process of overall development.
