中文摘要：

整合新经济地理学、现代经济地理学强调的地方化因素,构建了一个包含初始因素、增强因素和扩散因素在内的非均质空间产业集聚的分析框架,采用历史归纳分析方法,深入剖析了影响苏锡常地区制造业集聚、扩散的向心力和离心力及其变化过程。认为,自然条件和地理区位优势、历史积累的地方化因素、接近外部市场是苏锡常地区产业集聚初始向心力;地方政府的作用、集群和网络效应成为外资快速集聚的增强因素;环境污染和生态环境的恶化、要素价格上涨、区域开发重点转移导致向心力和离心力的微妙变化,导致近年来苏锡常地区部分产业呈现扩散趋势,并使得苏锡常地区制造业步入产业升级重要阶段。

The changing of market environment and the policy makes the centripetal force switch, which leads to foreign direct investment concentration in the region. And the role of the local government, cluster and network effects become the agglomeration of foreign capital enhance- ment factor.
