江苏省内一体化、制造业聚散与地区间分工演化

摘要/Abstract

摘要： 在区域一体化发展的过程中, 产业集聚和地区专业化在地区产业发展中相互关联, 是地区间分工的基础。通过对江苏省1984-2008 年间制造业空间集聚和扩散以及各地区专业化发展的关联分析, 发现地区分工深化与区域一体化并非同步, 不同时期对各类地区专业化发展具有不同的特征。区域一体化较低水平时期, 中心和外围地区专业化指数较高的同时存在“假性分工”的现象;一体化水平向较高水平发展过程中, 中心地区资源环境约束下可能凭借发达的产业基础率先步入升级通道使其专业化加深, 而外围地区的被动地位以及发展的冲动往往对产业承接的选择能力较差, 一定时期内专业化反而会出现下降。其原因是外围地区接受了大量的非优势产业, 其中有部分产业是中心地区淘汰的落后产能, 一定程度上预示着外围地区有可能会步中心地区先污染后治理的老路。

Abstract: In the process of regional integration, industrial agglomeration and regional specialization are correlated to each other and together are the basis for inter-regional division of labor. In this paper, the“shift-share” model and separated specialization indices for dominant and non-dominant industries are used in the analysis of the correlations between spatial agglomeration and expansion of manufacturing industries as well as the levels of industrial specialization in different parts of Jiangsu Province from 1984 to 2008. The analysis indicates that there is an inverted U-shaped relationship between the dynamic of industrial distribution (agglomeration and expansion) and the level of regional integration, consistent with New Economic Geography models. In addition, deepening of inter-regional division of labor doesn’t synchronize with regional integration; Regional specialization shows different characteristics at different stages of regional integration. In the case study of Jiangsu Province, for example, when the level of regional integration is relatively low, the specialization indices in central and peripheral regions are relatively high due to industrial agglomeration, coexisting with so-called“pseudo division of labor”phenomenon, caused by excessive agglomeration in the central region. When the level of regional integration increases, the central region, limited by the environmental resources, may utilize its advanced industrial basis and become the first to embark on an upgraded path and deepen the specialization, while the peripheral regions, lagged behind and eager to catch up, normally have few choices of industries, and the regions’ specialization levels are rather reducing during certain time period. The reason behind this is that the peripheral regions have to accept a large number of non-dominant industries, some of which are the ones with their productivities falling behind, being eliminated by the central region, using obsolete technologies, and/or causing serious pollutions. All of this indicates that to some extent the peripheral regions may have to take the same old route of“pollute first and then clean up later”that the central region has already gone through.
