Abstract:  

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.
