Abstract:

〗As a national marine economic development pilot region,the Yangtze Delta Region has become a more comprehensive system of marine industries.Four integrated comprehensive competitiveness’index item(ICCII),ten index,twentyeight factors have been constructed by means of theoretical analysis,factor analysis,analytic hierarchy process and expert consultation.A threelevel indicator system of regional marine industral competitiveness was established,which was composed by ICCII analysis and provincial level.It follows a technique route:（1) identifing index and analysis by using the combination of quantitative and qualitative methods;（2)integrating appraisal & analysis ICCII by using weightsum method.The results showed that based on the basic conditions of marine industry development in the Yangtze Delta Region,Zhejiang province is the bset,Jiangsu is better,and Shanghai is short;but at the next three ICCII,Shanghai is the best,Jiangsu nearly equal to Zhejiang.The spatial differentiation characteristics of regional marine industral competitiveness at provincial level are that Shanghai is out standing from other parts ,the expansion of the core to the periphery areas is declines from the core,but Jiangsu and Zhejiang are the wings for Shanghai.The spatial differentiation characteristics of regional marine industral competitiveness at ICCII & provincial level indicates that the marine industral were structural homogeneity and convergence,so we should integrated some production resource for marine economy of Jiangsu,Shanghai and Zhejiang to enhance the comprehensive competitiveness of the Yangtze Delta Region.Based on this,some strategies are proposed
