Evaluation And Policy Research For Coordinated Development Of Trade, Environment And The Urban

"the healthy development of urbanization" is specially emphasized as one of the six development strategy in the "The Eleventh Five-year Plan", and the coordinated development of urbanization, resources and environment is thought as the key field of state scientific research and has been risen to to the national strategy in both "National Middle/Long-term Plan for Science and Technology Development" and "National Plan of the Eleventh Five-year for Science and Technology Development". "The Twelfth Five-year Plan Early Major Problems Research Topic Selection Guide" points out that we must carry on the ecological civilization, promote the recycle economy development and construct low-carbon cities to promote the healthy and sustainable development of the cities. The healthy and sustainable urbanization has become the important content when constructing a socialist harmonious society. It is a positive response to the national strategy that we analyze the coordinated development of trade, environment and urbanization under the background of the open economy. It has a significant practical value for improving the overall environment quality and the city's ability to develop sustainably and promoting the coordinated development of trade, environment and urbanization under the background of the open economy.As a developed area in China, the Yangtze river delta has a rapid urbanization speed and the degree of openness is higher. During the progress of urbanization, whether the relationship between trade, environment and urbanization is coordinated or contradicted becomes an issue that is worth of study. In order to make the cities develop healthily and sustainably, this paper took the Yangtze river delta as an example to make a deep study about the coordinated development of trade, environment and urbanization under the background of the open economy. After analyzing the economic mechanism of interaction between trade, environment and urbanization, firstly, we constructed an evaluation index system on trade, environment and urbanization development level, and then used AHP to determine the weight of indexes of trade, environment and urbanization. And this paper calculated the development level of 16 cities's trade, environment and urbanization in Yangtze river delta. According to the coordinate development model, this paper estimated the coordinated development degree of the 16cities's trade, environment and urbanization. Based on the results, we divided the 16 cities into four types. And on the basis of evaluation, we make a scenario simulation. By comparing the different schemes, we proposed a way that trade, environment and urbanization can develop coordinately and provided some theoretical reference for the sustainable development of the Yangtze river delta.
