Study On The Relationship Between The Development Of Port Industry And City Based On Green Conception

The interactive relationship is dialectical in mutual promotion and restriction between port industry and city economic. Although port industry plays a very significant role in urban economy, it is evitable that port activities not only occupy a great deal of non-renewable resource such as coastal line, construction land and especially farm land of city and so on, but also bring pollution to its peripheral environment, that causing life quality reduction of local residents and other social problems as a result. Thus it is obviously important to pay attention to 'green' indicators when resource and environment have becoming bottleneck in today's economic development. At the same time, we should also evaluate comprehensive effect economic growth, resource consumption and environmental protection during the interaction process.Based on the systematic and scientific point of view, the paper analyzes the basic theory of the interactive development between the port and the city. It also puts forward that the interactive relationship between port industry and city economic is mutual promotion in the economy, and mutual constriction in the resources and environment. Then some evaluation indicators of port industry and city are respectively chosen from indicator systems of port and city. And the combination of Analytic Hierarchy Process and Principal Component Analysis is applied to establish evaluation indicator system and calculation model of coordinated relationship between port industry and city. In the end, Shanghai City is taken as an example to give demonstration of the theory and model brought up in the paper.Based on the related data of Shanghai from 1997 to 2006, quantitative calculations are done in ways of economic, resources and environment, and the evaluation of coordinated development between port industry and city in Shanghai is conducted. The calculation result shows the effectiveness of the proposed approach in the paper. The idea and method of the paper is of theoretical significance to other coastal port cities as well.
