中文摘要：

选择地区基尼系数和行业集中度指标测算了中国20个二位数制造业门类近10年的产业集聚水平，并对交通运输设备制造业、通讯设备及其它电子设备制造业和黑色金属冶炼及压延加工业三个门类进行了行业细化分析。结果发现，2002-2010年间我国制造业各行业区位基尼系数从总体上呈现先上升后下降的趋势，部分工业产品在东部沿海省市表现出很强的地区集中性，一些具有规模经济和范围经济性的行业集聚程度仍处于较低水平。地区基尼系数的变化得益于国家深入实施西部大开发和大力促进中部地区崛起战略。

英文摘要：

In this paper industrial agglomeration level of 20 two-digit manufacturing sectors in last decade is calculated via location gini coefficient and industry concentration ratio index. Additionally, industry-specific analyses are applied to three sub-sectors： transport equipment manufacture, communication ＆ other electronic equipment manufacture and black metal smelt ＆ roll processing. The results indicate that from 2002 to 2010 the location gini coefficient of Chinese manufacture industries increased first and then decreased; certain industrial products are highly centralized in eastern coastal provinces; certain industries of up-scale and scope economy features remain in low centralization level. The variation of location gini coefficient is attributable to China＇s western region development strategy and central region rising strategy.
