| Since 20th century 90's, Affronting the flinty condition of rapid increasing of population, the drying up of resources, the destroying of the environment, it is a new model of the economic globalization to develop the circular economy. Circular economy follows 3R principles: reduce, reuse and recycle. By the look of flow and Material form, circular economy has a mode of"resource- product- resource recovery"; all the material and energy can be sustainable used in it, so the activity of economy brings as little impact as possible to the environment. The requests of the circular economy are advancing its technical capability, practicing clean production and following the law of the nature to realize using the materials recycling. On the practice level of the circular economy there is enterprise level, industrial park level and district level.It is important to the government for their management to take the concept of circular economy to the development of region and research the circular economy at regional level. Also it is significant to make programming to study on the optimization of industrial structure. The essential features of regional circular economy are as the follow: (1) Economic benefits increase to satisfy the various require of people. (2) The development aim of region come true and the quality of life are improved. (3) Take the re-resources of material industry as the indicate industry of circular economy. Economize resource, and utilize the materials circularly. (4)Reduce the pollutants; restrain ecological degeneration and environmental pollution. We study the connotation and the character of circular economy and analysis the characteristic of the flow of the regional circular economy and put forward the concept of the degree of the circle. The result gives the foundation to this paper to establish the multi-objective goal programming model of regional circular economy. The model include four parts which are the aim of economy, the aim of society, the aim of environment and the aim of the degree of circle. It gives suggestion to the sustainable development by the calculation result. The model achieves the aim of the harmonious development of the compound ecosystem of economy- society- environment.Take the city of Shishi and Xiamen which are in Fujian province and the city of Zhangjiagang which is in Jiangsu province as examples, put the technical economic parameter, the 11th Five-Year Plan aim date and the condition of the industry structure of the there cities to the multi-objective goal programming model, we do some programming and forecasting research. The calculation result shows that the multi-objective goal programming model is feasible. The result gives advice of choosing of the technology parameter, the direction of adjusting of industry structure and the suggestion of the development. |
