| In such an era that economy and finance are increasingly globalized, market-oriented and information-prioritized,financial institutions inside those are shaping up even closer linkage and cooperation. Finance agglomeration is becoming one of the important indexed showing the competitiveness of a certain region and enhancing the region economic.The paper cites the coupling relationship from physics; it is the first time to the study on relationship between finance agglomeration and regional economic. And it synthetically apply finance,econometrics,industrial economics,system science and other relative ways,explore the coupling theory between finance agglomeration and regional economic in Bohai Sea Ring Area and then estimate the coupling harmony between them with the coupling and harmonious model.And then the paper make recommendations to enhance the coordinated development between finance agglomeration and regional economic in Bohai Sea Ring Area.The paper mainly analyse the coupling relationship between the finance agglomeration and regional economic in Bohai Sea Ring Area in two points of view,one is theoretical and the other is empirical.First of all,the paper review the rate of progress of the existing papers on the finance agglomeration,then point out the inadequacy of existing research papers and definitude the direction and focus to this paper; Secondly, cites the definition of coupling,with which the paper analyse the interactive coupling mechanism between the finance agglomeration and regional economic,including the factors which influence the finance agglomeration and the regional economi effects which influenced by finance agglomeration. Thirdly,the paper estimate the development of finance agglomeration and analyse the factors which influence the finance agglomeration.The results shows that the finance agglomeration has been formed in Bohai Sea Ring Area,and the mainly factors which influence the finance agglomeration are economic of scale and government. Agglomeration of qualified personnel in financial and the trade needs also play roles in the finance agglomeration.After that, the paper analysed the degree of coordinated development of regional economic and finance agglomeration.On the basis above,the paper do the empirical analysis to the coupling relationship between finance agglomeration and regional economic with building the coupling harmony model.And the empirical analysis educed the following conclusions:the finance agglomeration in Bohai Sea Ring Area is in the stable stage of development,and the coupling relationship between it and regional economic is well and high qualited harmony.Otherwise the synchronization between them don't match very well,which need further improved.In the end , the paper provides policy recommendations to improve the finance agglomeration in Bohai Sea Ring Area,and to enhance the developmeng of economics. |
