Study On The Development Path Of Integrated Port-vicinity Industry Based On Regional Carrying Capacity

With the development of the world economy, many countries are more and more attention of the development of port-vicinity industry. However, as a kind of resource-intensive industries, port-vicinity industry has formed enormous dependence on the land, marine, coastline and energy in promoting economic growth. But the limitation of resources environmental capacity formed a backlash on the development of port-vicinity industry, the interaction between them objectively promoted the formation of the mechanism between port-vicinity industry and regional carrying capacity. So it's especially important for the analysis of the development path of port-vicinity industry to clarify the mechanism between regional carrying capacity and port-vicinity industry.Firstly, the article gives the definition of regional carrying capacity on the basis of literature review, and from the integrated point of view, recognizes the influence factors of integrated port-vicinity industry based on the regional carrying capacity recurring to the hierarchy identification model, and based on this constructing the evaluation index system. Then the article introduces gray correlation analysis and fuzzy integral methods and has set up an decision model of development path of integrated port-vicinity industry based on regional carrying capacity.At last, on the basis of an example analysis, the article conclusion that: various factors of regional carrying capacity play different roles on the development of integrated port-vicinity industry, including the restricting effects of regional environment, supporting effects of regional resources, auxiliary effects of infrastructure of the hinterland, adjusting effects of regional soft power and decisive effects of port location. Through the decision model can obtain three aspects of the path decision evidence: the bigger grey correlation of an industry is, the greater its contribution to the GDP is, so this industry should be developed priority to promote the economic development; the bigger fuzzy evaluation index of an industry is, the better its bearing status is, so the development threaten to regional capacity is small; to every industries, the smaller element's evaluation after defuzzification is, the bigger its constraint to the industry development is, and this element becomes the bottleneck of the development of this industry.
