| With the trend of global warming becoming more apparent, CO2emissions gradually attracted world wide attention. Since the1990s, China’s economy gained rapid growth, industrialization and urbanization acceierated, and the relative living standards improved, but also paid a huge environmental costs—CO2emissions increased. In2008, China has surpassed the U.S. as the world’s largest CO2emitters. Under the background of global advocating energy saving and emission reduction, as a responsible nation, China will also shoulder the great responsibility of reducing CO2emissions. However, while in seeking to control and reduce CO2emissions, China’s economy should not be hit. Therefore, it is necessary to study the relationship between balancing the "low CO2" and economic development. From this perspective, this article explores the content of CO2emissions and economic development coordination, measures the coordination of China’s CO2emissions and economic development and puts forward some corresponding suggestions on this basis.The article consists of6chapters:Chapter1is an introduction, which introduces the research background, the significance of the topic, the research thoughts, the research methods, the main innovations, and the overview of relevant domestic and aboard research literatures. Chapter2is the cornerstone theory of this article, which first introduced the theory of ecological economics, sustainable development theory, low-CO2economic theory and so on, then on the analysis of the relationship between CO2emissions and economic development. Economic development was divided into three dimensions—economic growth, economic structure and economic efficiency. Finally the concept and content of the coordination between CO2emissions and economy development were extended. Chapter3,4,5were the subject of this study. Specifically, in Chapter3, from the following four aspects——CO2emissions, economic growth, economic structure, economic benefit, a total of30specific indicators were selected to build the comprehensive evaluation index system of the coordination between CO2emissions and economic development. In Chapter4, China’s1990-2009annual CO2emissions and economic development status was analyzed. Chapter5is the part of quantitative analysis in this article. First, using factor analysis, the overall levels of CO2emissions, economic growth, economic structure and economic benefit from1990to2009in China were evaluated, then principle component analysis was chose to obtain comprehensive evaluation of the level of economic development on the basis of the three dimensions, also built VAR model to fit the coordination group for each index value. Last, the model of membership function coordination degree in fuzzy mathematics were made use of, to measure the static and dynamic coordination of CO2emissions and economic development (economic growth, economic structure, economic benefit) in China. Chapter6is the conclusion of this article, where some recommendations and outlook section were also given. According to the result of quantitative analysis, the policy recommendations such as optimizing energy structure, transforming economic growth, accelerating the upgrading of industrial structure, enhancing economic efficiency, and so on, were proposed. Also, the future development of relevant prospects was discussed and forecasted.The basic conclusions were shown as follows:Conclusion1:The comprehensive evaluation level of CO2emissions in China had a greater level of volatility. During1990-2009, due to the balance between the CO2emissions and CO2intensity scale, unit energy consumption, it showed greater volatility. Specifically, from the year1990to2001it presented lower trend in a slight fluctuations, and rose gradually after reaching its lowest point in2001, then declined again after reaching its lowest point in2006.Conclusion2:Comprehensive evaluation of the level of Economic growth, economic structure, economic efficiency, and economic development showed a rising trend year by year. During1990-2009, comprehensive evaluation of the level of the above4had a basically same trend—a rising trend year by year except for a few years of fluctuations, which meant steady growth of economic size, gradually optimization of economic structure and a gradual increase in the economic benefits in China at this stage.Conclusion3:From the prospective of static coordination evaluation index, the CO2emissions and economic development (economic growth, economic structure, economic benefit) in China were overall in the state of basic coordination, and the same as years except the years of1991,1996and1997. In addition, except for a few years, their movements are basically the same.Conclusion4:From the prospective of dynamic coordination evaluation index, dynamic coordination between CO2emissions, economic development and various dimensions of economic were also overall in the state of basic coordination. They fluctuated comparatively before1998, tended to be stable in subsequent year and entered the steady basic coordination state after2002, which presented that, as the time went far, CO2emissions and economic development were in a trajectory of coordinated development.The innovations of this paper were shown as follows:Innovation1:on the basis of existing research, the paper extended the concept of coordination between CO2emissions and economic development, divided the concept of economic development into three dimensions—economic growth, economic structure and economic efficiency, and defined the contents of coordination between CO2emissions and economic development from the point of coordination between CO2emissions and the three dimensions of economic development, which to make up the defect of lacking attention about the coordination between CO2emission and economic development in the previous reseach.Innovation2:Based on the principles, such as science, integrity and relevance, authenticity and comparability, availability and operability, and so on of this kind, the comprehensive evaluation index system of coordination between CO2emissions and economic development was established from four aspects:CO2emissions, economic development (economic growth, economic structure, economic benefit), which to make up the bias only choose a few indicators to measure the relationship between CO2emissions and economic in the past.Innovation3:Using factor analysis, the overall levels of CO2emissions, economic growth, economic structure and economic benefit from1990to2009in China were evaluated, which can make up a lack of objectivity in ever comprehensive evaluation method which to calculate the index weights. On this basis, though building coordination model learning from concept of membership function coordination degree in fuzzy mathematics, the paper measured the both static and dynamic coordination between CO2emissions and economic growth. This method was of some scientific and operational, which contributed to an objective evaluation of the coordination between CO2emissions and economic development, and could also make up for the deficiency about lack of measurement of coordination between them in the previous studies. |
