制造业区域产业专业化、竞合关系与分工——基于江苏省市域面板数据的计量分析

运用产业专业化指数、竞合关系模型与产业分工指数测度了2001~2015年间江苏省制造业产业专业化、竞合关系与分工状态及其演进特征，同时运用随机效应函数分析了制造业区域分工的驱动因素。研究发现：江苏省制造业专业化演进呈现出苏南地区主导产业数量减少，苏北地区主导产业数量增加的特征，整体竞合网络结构较为稳定，但是局部竞合网络结构变化较大，江苏省制造业区域分工整体上呈现出了先增大后减小的趋势。产业专业化与区域间的合作促进了区域产业分工，但是当区域间存在较大的经济发展差异时不利于制造业的区域分工，同时距离过近的区域间容易形成区域产业竞争关系，也不利于区域分工关系的形成。

Regional Industrial Specialization,Co-opetition Relations and Division of Labor in the manufacturing industry：Econometric Analysis Based on Panel Data in Jiangsu Province

The new industrial division of labor has explained the rational allocation of the elements on industrial level, and shown the effect of industry specialization at regional level. Because labor division would results in the difference of industrial functions across cities, the industrial division and the level of industrial development would also be alienated. Regional industrial division can not be separated from regional industrial cooperation. Regional cooperation also strengthens the complementarity of industrial functions between cities. The industrial specialization index, co-opetition relation model and industrial division index were used to measure the specialization, co-opetition and division of labor status and evolution of manufacturing industry in Jiangsu Province during 2001-2015. Meanwhile, the influencing factors of regional division of labor in manufacturing industry were analyzed by random effect function. The results found that: 1) The evolution of manufacturing specialization in Jiangsu province showed a decrease in the number of leading industries in southern Jiangsu, and a increase in the number of leading industries in northern Jiangsu. 2) The overall cooperation-competition network structure was relatively stable, while the local competing network changes significantly. The regional division of manufacturing in Jiangsu showed the trend of first increase and then decrease. 3) Industrial specialization and regional cooperation promoted the regional industrial division, but it was not conductive for the regional division of labor in manufacturing when there was a significant difference of economic development among regions. At the same time, it was easy to form regional industrial competition between areas that were too close to each other, which was adverse to the formation of regional division of labor.
