The Research Of Development Model Of Regional Circular Economy

Circular economy is a generic term for the reducing, reusing and recycling activities in the process of production, distribution and consumption. At present, the research of circular economy on enterprise level and industrial park level are quite comprehensive, but it’s still less on regional level. The reginal level has biggish geographic area boundaries, numerous population, perfect industrial structure and abundant resources, at the meanwhile, there are many differences between different regions, so it’s very necessary to implement the circular economy on regional level. This dissertation takes the regional circular economy as the object of study, at first, discuss the definition and connotation, then summarizes the domestic and overseas research achievement, and analysis the development model from the angle of industry of industry and resource respectively, and at last, establishes the comprehensive evaluation system.This dissertation argues that, the regional circular economy is a scientific development mode that takes one single administrative region or some administrative regions’group as the scope, considers the region’s existing resources conditions and industrial structure, based on the theoris of circular economy, regional economy, industrial economy, and ecological economy, sets the developed economy, resource efficient, environmentally friendly and social harmonious as the goals, according to principles of reduce, reuse, recycle, sustainable and adjust measures to local conditions, raises the development level of circular economy in the industry interior and also related other industries, improves the utilization efficiency of each resources, and simultaneously ensure the policy, capital, technology and talents as support system.The industry and resource are the main subjects of adjust in regional circular economy, in order to analysis the development model of circular economy on the point of industry, this dissertation investigates 18 industries, the primary industry includes the agriculture, forestry, animal husbandry and fishery, the secondary industry includes the coal industry, petroleum industry, chemical industry, power industry, steel industry, non-ferrous metal industry, machinofacture industry, electronic information industry, light industry and construction industry, the tertiary industry includes the transportation, tourist industry, catering industry, retail business. Based on the analysis results, generalizes the development models of circular economy for primary industry, secondary industry and tertiary industry respectively. At last, puts forward the development model of regional circular economy from the angle of industry, that is based on regional original industrial chain, increases the longitudinal extension industrial chain for the main resource’s deep processing, the horizontal extension industrial chain for associated resources’comprehensive utilization, and the reverse regression industrial chain for transforming the waste to into resources, constructs a complex industry network with significant circulation characteristics by the related diversification, makes the resource realize the maximization of the use efficiency, and minimum the waste disposal at the end.At the meanwhile, the development model of regional circular economy from the angle of resource is also important, because the resources efficiency improvement has connections with industrial structure optimization, the industry is the statical processing unit, while the resource is the material flow, and also, the industry and the resource are not always correspond. This dissertation takes the water resource, energy resource, land resource, and solid waste as the objects of research, discuss the water resource’s development, protection, conservation and regeneration; the optimization of conventional energy sources, new energy development and energy conservation; the land resource’s development, conservation and recovery:and the solid waste’s source reduction, source classification, and reclamation, based on the analysis result, puts forward the development model of regional circular economy from the angle of resource, that is based on the regional original resource utilization, takes the resources’source increase as the starting point, takes the resources’exploitation reduction and the intensive utilization as the principles, and takes the waste resources’reclaiming as the core,improves the output capacity, reduction rate and and circulation rate of resources substantially, meanwhile, decrease the environment pollution effectively.And at last, in order to evaluate the current circular economy development level of and in particular compared with other regions, this dissertation establishes the evaluation system of regional circular economy, first, analysis the gradation of evaluation system, obtains and synthesizes the indicators from the China Statistical Yearbook; then designs the "sort comparison method" in accordance with level analysis method, used to decide the weight of the indicators, in the sort comparison method, the judgment matrix has a favourable consistency; in the process of standardization, in order to ensure the dispersibility of the standardization results, transforms the extremevalue standardization into "extremevalue midvalue standardization", analysis the obtaination of midvalue and the shape of the score function, stress the judge method of failure of quadratic function, the result show that, when the distances ratio of midvalue and two extremevalues greater than (?), we should use the piecewise linear function, then puts forward the score functions of indicators in different situations, also provides the computing method of comprehensive index and criterion index, these indexes are relative comparative results. Using the evaluation system to estimate the development level of circular economy of provincial regions of China in 2009, the result shows that Tianjin and Beijing have a higher level in circular economy, and eastern regions are better than western regions. Then using the evaluation system to estimate the development level of circular economy of municipal regions of Shandong province in 2009, the result shows that. Weihai and Qingdao have a higher level, and the distribute of circular economic index rises gradually from the west to the east, the specific evaluate results can provide the accordance for circular economy’s development decision-making of each region.
