The21st century witnesses the increasingly severe problem of resources and environment, along with the tendency of economic glbbalization and innovation globalized and integrated economy and its challenges. Hence, in order to improve international competition, realize the strategic aim that sustainable development of both economy and environment and creates a win-win situation, the method of economic growth must be transformed actively. This has become a consensus of all the nations. Therefore, to develop a circular economy has become an option for the development of the world economy gradually. This new norm of circular economy has been considered as an effective approach to solving the long-existing intense conflict between environment and development fundamentally and to realizing the development of both man and the nature harmoniously.With the increasing applications of circular economy in regions, regional circular economy has become a new sustainable norm of regional economic development, which has been playing a great role in promoting the region’s overall development. It is able to remedy the flows of traditional regional development norm, and motivate the lagging region to realize a leap in its development. Regional circular economy, which is based on regional economy or regional development, is a complex three-dimensioned super system of economy, society, and environment, including regional industry system, regional infrastructure system, and regional ecological environment system. The core content of regional circular economy involves the following parts:optimizing the operational structure and relevance of the key elements of the system through recycling regional and cross-regional material, energy, information, resources and waste; realizing the function of industry circular development, coordinating regional industry structure, and transforming the method of regional production, consumption, management by the means of setting up various industry ecological chain in the region; creating a ecological network of regional production, consumption, waste disposal and regional management with the help of public facilities and assisting service organizations; enhancing regional and cross-regional communication, and meeting the need of realizing the scale profit of circular economy and the need of solving problems of regional projects by scientifically designing cross-regional cubic network. Therefore, an evaluation of regional circular economy development is a premise for regional circular economy development to enter the operation phase from the theoretic exploration phase.We systematically research on regional circular economy’s evaluation index system by an analysis and comprehensive evaluation of regional circular economy in our country and in the world. Through comparison, we find that the research of regional circular economy in our country mainly focuses on its basic theory and ways to realize it, whereas there is a lack of the research on an evaluation system based on the features of regional circular economy. So we construct a regional circular economy evaluation index system which is a tree structure evaluation index system divided into overall objective layer, evaluation objective layer and index layer from the top to the bottom. Evaluation objective layer includes four sub-objective such as resources exploitation, resources output, resource’s utilization and waste disposal. Under each sub-objective there are final index. This evaluation index system is a framework of circular economy evaluation system with clear structure and definite objective, and its basic analyzing method involves industrial metabolism analysis, life cycle evaluation, ecological efficiency evaluation and so on so that optional adoptions are available for different situations in different regions.We combine comentropy and the unascertained measure, and construct a circular economy evaluation model based on comentropy and the unascertained measure which we adopt as an effective tool to evaluate regional circular economy. The regional circular economy evaluation index system and evaluation model we construct collect northeast china provinces’waste disposal accumulated data (2004-2007), Liao Ning province’s annual waste disposal data (2001-2007), and the waste disposal data of14cities in Liao Ning province (2001-2007) as research target and carry out an integrated evaluation. The research result is the pollution discharges in Hei Longjing province and Ji Lin province are lower than that in Liao Ning province. GDP-related pollution combined effect ranking and the ranking of waste disposal absolute number in these three provinces are of great difference. As opposed to the growth of GDP, waste disposal’s combined effect is increasing year after year. At the same time, the absolute number of waste disposal is on a remarkable rise too. The evaluation on the14cities’waste disposal in2007shows the situation of pollution is worse and worse annually with the increase of GDP in each city. But effective restriction of waste disposal will be beneficial to further improve and realize the sustainable development of regional economy.Based on the above-cited theory and the result of our empirical study, we put forward a regional circular economy development mechanism and guarantee system. A development mechanism which includes optimization mechanism by governmental macro-control, promotion mechanism by regional circular economy basis construction, incentive mechanism of regional circular economy development, and social participation mechanism of clear responsibilities, and a guarantee system, which involves an institutional innovation system, an technological innovation system, a legal system, and a statistic system to perfect regional circular economy development, will largely support and guarantee the successful application of the circular economy development norm, and the healthy and continuous development of the natural and social economic systems in regions.
