利用产业基尼系数和行业集中度CRn指标对中国20个大类制造业门类的集聚性进行了测度,并对其中主要的3个门类进行了细化研究,得出结论:中国制造产业的总体集聚程度正在不断提高,部分制造业已显现出很强的集中性,且主要集中在东部沿海省市,但一些规模经济和范围经济性强、在国外具有显著集聚特征的行业的集聚性还比较低。同时发现,产业集聚和地方化呈现增长趋势,电子及通讯设备制造业产业集聚程度与工业经济增长呈现高度的正相关性。
The agglomeration of manufacturing industry in foreign countries has been studied since 1980s, but there are few such studies in china. In the paper, the agglomeration level of 20 two-digit manufacturing industries was measured by the concentration index of industrial space and CRn index in 2002-2005. The result indicates that the whole agglomeration level of China's manufacturing industry is raising continuously and find that some industries show higher degree of concentration in the concentrated .The agglomeration cal representative of industrial increase of industry. eastern level cluster. china, but some industries characterized of scale of electronic and equipment manufacturing industry The positive correlation is and scope is highest presented between agglomeration economies are less and it is the typilevel and economic
