产业集聚向心力和扩散离心力的变化过程——以改革开放以来苏锡常地区制造业聚散为例

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

DYNAMIC OF THE CENTRIPETAL FORCE AND THE CENTRIFUGAL FORCE IN THE PROCESS OF INDUSTRY AGGLOMERATION AND DECENTRALIZATION——A CASE STUDY OF SUZHOU-WUXI-CHANGZHOU REGION IN THE YANGTZE RIVER DELTA

The region of Suzhou-Wuxi-Changzhou,which located the center area of the Yangtze River Delta,is called as Sunan with the social,cultural and economic depth blending.Since the reform and opening,the region gets breathtaking industrial growth.Based on the new economic geography perspective,this paper suggest that the natural condition and geographical location advantage,the localization of the historical accumulation,close to the external factors market are the industrial agglomeration of town and village industry especially initial centripetal forces.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 enhancement factor.Ecology deterioration of the environment,increasing of elements price conduce to the present industry spread in recent years,which propels the industrial upgrading.
