Analysis Of Efficiency Evaluation On The Circular Economy In China

Along with fast increase in population, rapid consumption of resources, together with loose environmental requirements, sustainable development of society is now at stake. Therefore, the focus of moden society is efficient use of resources, protection of the ecological environment, and promotion of the sustainable development of the economy & society. While the idea of sustainable development has gradually become mature and strikes root in the hearts of the people, increasing theorists and policy makers in all countries concern an effective means for the sustainable development, i.e. circular economy. It turns out to be a fact that circular economy is the best option to solve the aforementioned problems.Nowadays, our government and relevant departments have deeply understood the importance of developing circular economy, and thus make plenty of work. As is known, efficiency is defined as a means by which the maximum output can be obtained via the minimum input. It is the key of economics. Started with the viewpoint of efficiency evaluation, this paper basically builded up a universal index system of efficiency evaluation on the developing level of circular economy, with the corresponding index systems found in documents as reference, based on China Statistical Yearbook 2006 and China Environment Yearbook 2006. Moreover, by means of data envelopment analysis, or DEA, of the efficiency evaluation on the developing level of 30 regions in china during 2003～2005, this paper caculated such aspects as DEA efficiency value, super-efficiency DEA value, DEA scale efficiency and projecting analysis of each region. Combining the results from DEA projecting analysis with resource allocation of circular economy, the optimium allocation of circular economy can be achieced. Furthore, this paper also clarified the reasons for the low input/output ration of circular economy for each region, and put forward the corresponding measurements of promoting this ratio. The last part put forward the further research issue for this subject.
