江西省制造业产业集聚、地区专业化与经济增长实证研究

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

采用2006—2009年江西省11地级市20个制造业构成的时间—地区—行业的三维面板数据,实证分析产业集聚、地区专业化与经济增长的关系。结果表明,产业集聚、地区专业化与经济增长之间的关系并不是简单的线性关系,而是呈现倒U型的关系,并运用新地理经济学的相关理论分析拐点出现的原因。结果表明:追求经济增长最大化时,加工制造业较非加工制造业需要更高的专业化水平,非加工制造业较加工制造业需要更高的集聚水平;要素禀赋高的鄱阳湖地区较要素禀赋低的非鄱阳湖地区可以达到更高的产业集聚、地区专业化水平;江西省11个地区的产业集聚、专业化水平远没有达到经济增长最大时的水平。

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.
