武汉城市圈制造业集聚的实证研究

AN EMPIRICAL STUDY ON MANUFACTURING INDUSTRIAL AGGLOMERATION IN WUHAN METROPOLITAN

采用调整后的产业集聚EG指标,结合产业集中度指数,对武汉城市圈2000～2007年制造业19个行业的集聚程度进行了精确的测度,并分别从制造业集聚度变动趋势、产业集聚度特征、产业集聚空间分布特征、增长集聚弹性等角度进行了详细的分析。结果表明:考察期间武汉城市圈制造业的区域集聚度较高,而且中高技术行业集聚特征十分明显,资源性和低技术行业较为分散;从行业的区域集聚空间分布特征来看,产业集中度较高,主要集中在武汉、黄石、孝感和黄冈4市,其它5个城市产业集中度较低,城市上榜次数较少,且上榜行业主要集中在资源性和低技术行业,形成了以武汉等4市为中心,其它5市为外围的"中心-外围"结构;构建的产业集聚弹性模型计算结果表明,整体上城市圈制造业集聚弹性较大,但不同行业间的弹性值差距明显。

Based on the improved industrial agglomeration EG and concentration ratio index,the agglomeration level of 19manufacturing industries in Wuhan metropolitan from 2000to 2007was measured.By means of analyzing their agglomeration level movement,spatial distribution,feature of industrial cluster and elastic growth,the essay made the conclusion that the elasticity of concentration held a high standard,but the disparity of different industries was still obvious.The essay also demonstrated that Wuhan metropolitan agglomeration still remained high concentration level so as to make substantial development in the future.Some problems was discovered that manufacturing industries agglomeration level only limited in the four cities of Wuhan,Huangshi,Xiaogan and Huanggang.And the other 5cities of Wuhan metropolitan seldom hit the city list as the result of their underrated agglomeration,resource-consuming and poor technology field.Consequently,all these contribute to 4cities appeared to be typically centralized,and the other 5cities circled.
