【摘要】:目前,发展循环经济已经成为国际社会的普遍趋势,我国也不例外,有越来越多的城市或区域都组织进行了循环经济的规划。为了使我国循环经济规划研究具有比较科学实用的评价方法,本文使用生态效率来评价区域的循环经济发展状况。本文的研究思路是将数据包络分析方法(Data Envelopment Analysis, DEA)引入到生态效率评价中,借鉴国内外学者关于生态效率的研究,建立区域生态效率的评价方法体系,并以辽宁省为例进行实证研究。 首先,介绍了循环经济和可持续发展理论。循环经济是指人类要建立一种能够充分利用大自然资源的新的发展机制,同时在生产活动中尽量减少对生态环境的影响和破坏,最终达到经济发展和环境保护的“双赢”。可持续发展理论要求满足当代社会人类的生活需要,同时也要满足后代自身发展的各种生活需要,是一种全方位的、可持续的发展。循环经济本质上是可持续发展理论的经济体现。 其次,通过对DEA方法的研究,选择了三个计算生态效率的DEA模型。DEA方法是在“相对效率评价”概念基础上发展起来的一种系统分析方法。DEA模型可以根据不同的分类标准分为众多种类,对比分析不同DEA模型,本文最终选择了DEA基本模型C2R、BC2以及超效率DEA模型SE-DEA,来计算区域生态效率。 最后,对辽宁省区域生态效率进行了实证研究。选取2005~2009年辽宁省各城市的生态效率数据,采用C2R、BC2以及SE-DEA三个DEA模型进行了实证研究。结果发现,在2005~2009年期间,沈阳、大连以及盘锦的相对生态效率一直有效,并同时达到技术有效和规模有效,其中沈阳的相对生态效率最高,SE-DEA达到了2.91。对于其他十一座相对生态效率无效的城市来说,从输入指标的冗余率来看,废气排放量、固体废弃物排放量以及万元GDP能耗的冗余率都处于较高的水平,这三个因素是导致它们相对生态效率无效的主要原因。因此,可以通过加强对这些因素的控制,来有效的改进生态效率。
[Abstract]:At present, the development of circular economy has become a general trend of the international community, China is no exception, more and more cities or regions have organized the planning of circular economy. In order to make the study of circular economy planning in our country more scientific and practical, this paper uses ecological efficiency to evaluate the development of regional circular economy. The research idea of this paper is to introduce the data Envelopment Analysis (DEAA) method into the ecological efficiency evaluation, draw lessons from the domestic and foreign scholars' research on ecological efficiency, and establish the evaluation method system of regional ecological efficiency. Firstly, the theory of circular economy and sustainable development is introduced. Circular economy means that human beings should establish a new development mechanism which can make full use of the natural resources, at the same time, reduce the impact and damage to the ecological environment in the production activities as far as possible, and finally achieve the "win-win" between economic development and environmental protection. The theory of sustainable development requires to meet the needs of human beings in contemporary society, and at the same time to meet the needs of future generations themselves. It is a kind of all-round and sustainable development. Circular economy is essentially the economic embodiment of sustainable development theory. Secondly, through the study of DEA method, This paper selects three DEA models for calculating ecological efficiency. DEA method is a system analysis method developed on the basis of the concept of "relative efficiency evaluation". The DEA model can be divided into many kinds according to different classification criteria, and different DEA models can be compared and analyzed. In this paper, the basic DEA model C2RX BC2 and the super efficiency DEA model SE-DEAare are selected to calculate the regional ecological efficiency. Finally, an empirical study on the regional ecological efficiency of Liaoning Province is carried out. The ecological efficiency data of cities in Liaoning Province from 2005 to 2009 were selected, and three DEA models, C2RX BC2 and SE-DEA, were used to carry out empirical research. The results showed that the relative ecological efficiency of Shenyang, Dalian and Panjin had been effective from 2005 to 2009, and the relative ecological efficiency of Shenyang had reached 2.91. For the other 11 cities with relatively ineffective ecological efficiency, the redundancy rate of the input indicators shows that the redundancy rates of exhaust gas emissions, solid waste emissions and 10,000 yuan GDP energy consumption are all at a relatively high level. These three factors are the main reasons for the invalidity of their relative ecological efficiency. Therefore, we can effectively improve ecological efficiency by strengthening the control of these factors.
