Research On Dynamic Evolution Of Correlation Effective Of Regional Shipbuilding Industry And Its Structure Optimization And Upgrading

Based on the theory of industrial development,theory of industrial agglomeration and theory of industrial correlation,we choose the shipbuilding industry in the Yangtze River Delta,Pearl River Delta and Bohai Rim as the research object.On the basis of understanding the status and problems of regional shipbuilding industry,we analysis the spillover effect and correlation effect between shipbuilding industry and regional economy.By building a three-dimensional evaluation system,we analyze the industrial structure of the regional shipping industry and then put forward the adjustment strategies and suggestions,in order to promote the sustainable development of the regional shipping industry.First of all,when analyzing the development status of the regional shipping industry,we should make clear the industrial positioning,strategic planning and its geographical distribution,industrial layout and major economic indicators.On the basis of above,we measure the degree of specialization and agglomeration of shipbuilding by means of location quotient and space Gini coefficient.And pointing out the existing problems from the perspective of coordinated development of industrial chain based on the analysis results.Secondly,in order to solve the problems existing in the development of regional shipping industry,it is necessary to analyze the status and role of shipping industry in the regional economic network.With the help of the Feder-model,this paper analyzes the spillover and feedback effects of regional shipping industry on regional economy and quantifies the extent to which regional shipping industry supports economic growth.Furthermore,I-O model is used to evaluate and analyze the integration and interaction between shipbuilding industry and other related industries.Based on the input-output data of the region from 1992 to 2012,the dynamic characteristics of the shipbuilding industry and related industries at different stages of economic development are summarized and refined,and the relevant factors are decomposed.Based on the above analysis,we establish a regional shipbuilding industrial structure adjustment system that includes the three dimensions of industrial linkages,factor inputs and economic efficiency.Determining the spatial position of the industries associated with the shipbuilding industry in the three-dimensional system and then choosing the adjustment path of the industrial structure of the shipbuilding industry.Finally,this paper proposes strategies of transformation and upgrading of the shipbuilding industry that is in line with the characteristics of regional development.
