An Empirical Study on Industrial Agglomeration,Regional Specialization and Economic Growth of Manufacturing Industry in Jiangxi Province

By forming three dimensional panel data of time-regions-industry,the paper analyses empirically the relationship of industrial agglomeration,regional specialization and economic growth.The empirical results show that the relationship between industrial agglomeration,regional specialization and economic growth is not a simple linear relationship,but an inverted u-shaped relationship.The paper uses new geographical economics to explain why there is an inflection point.The results show that processing and manufacturing needs a higher level of specialization than other manufacturing,and other manufacturing requires a higher level of concentration,when the enterprises pursuit the maximization of economic growth;Poyang Lake region with high factor endowments can achieve a higher level of industrial agglomeration and regional specialization than non-Poyang Lake region;the 11 regions in Jiangxi province far from reaching the maximum level of industrial agglomeration and regional specialization.
