| Industrial civilization not only bring quickly growing to economy, but also serious waste of resources and environmental pollution, which far beyond the carrying capacity of the earth. The development of human has encountered hitherto unknown obstacles. The industrial revolution brought a series of negative effect, which caused human thinking,and sustainable development emerge as the times require. Since the1990s, with the strategy of sustainable development implemented universally within the world, industrial ecologicalization development more and more popular in developed countries. From the choice of national industry development strategy, management legislation of the macroscopical level, construction, layout of regional industrial park of the middle level to production technology and implementation of clean production of microcosmic level ecology is always one of the main line.Ecological industry development in our country is relatively weak, compared with the developed countries there is still a big gap. And according to the situation of our country,inside quite a long period, the proportion of the third industry will not come to70%to80%as developed countries,and the second industry especially the industry still is the key to the development.With the increasingly global warming, greenhouse gas emission reduction has become the responsibility and consensus of completed mankind development. Low-carbon economy has become the focus of attention and inevitable choice of the whole world. Unreasonable Industrial structure, irrational use of resources and waste will damage the environment sustainability. Low carbon economy development mode requires the healthy development of the economy and reduce damage to the environment, which requires the realization of ecological industry. This article set out from the perspective of low carbon economy, based on low carbon economy and industrial ecology theory, analysis of the affecting factors of ecological industry and constructs the evaluation index system of ecological industry, collection, collation data and analyze the ecological industrialization level of our country, the development status of ecological industry, identify the cause of the development problem.There are five chapters. The first chapter is introduction, mainly elaborated the background of industry ecology from the perspective low-carbon economy, significance, relevant literature review, research methods and innovation, and fully analyze and describe the conceptual framework for the study. The second chapter is the theoretical basis, review of industrial ecology, circular economy theory, the theory of decoupling, Kuznets environment theory. The third chapter analyse the present situation of Chinese industry ecology, including the current status of industrial ecology, characteristics, necessity, main influence factors and other content. In the fourth chapter, on the basis of the principles, construct evaluation index system and interpretate the listed index. The fifth chapter analyse the level of industry ecology. Descript the method and step of principal component analysis, Selects39industries and use SPSS software to handle data, construct the principal component synthesis model, calculated the level and analyse the reasons. |
