Influence of Industrial Co-agglomeration on Industrial Structure Optimization——Based on The Empirical Analysis of High-tech Industry And Producer services

Wang Yan;Sun Chao;  
Based on the internal connection between high-tech industries and producer services and the mechanism of industrial co-agglomeration of the two types of industries on the optimization of industrial structure,the dynamic panel GMM model is adopted to verify the driving effect of synergistic agglomeration of the two types of industries on the optimization of industrial structure in Chinese provincial regions from 2003 to 2016. The results showed that: the industrial co-agglomeration through unceasingly promote the industrial division of labor refinement,industry chain extension and complementary industry grow up together,and then promote the industrial structure,through factor coupling and industry symbiotic economic effect,improve the industrial structure rationalization,but under the dual influence of technical knowledge spillover effect and negative output increase,the industrial co-agglomeration have certain negative influence on industrial structure of the clean,and the influence on the region shows a tendency of the east is better than that of middle and west; From the perspective of industry matching analysis,high barriers to entry and long product RD and application cycle of high-tech industries have a higher degree of industrial co-agglomeration with producer services,and the collaborative agglomeration with knowledge-intensive services has a more significant impact on the optimization of industrial structure.
