产业协同集聚对制造业效率的影响研究

Research on the Influence of Industry Collaborative Agglomeration on Manufacturing Efficiency

以2006—2015年全国31个省份为样本,分别运用OLS和GMM估计方法从实证角度验证生产性服务业和制造业协同集聚对制造业效率先促进、后抑制的倒U型影响。结果表明:在其他条件不变的情况下,产业间的协同集聚程度有一个合理区间,当某地区的协同集聚程度远远低于最优值时,应当采取相应的政策鼓励二者共同发展,提高制造业效率。相反,应该适当外迁部分企业,使协同集聚程度保持在合理范围内。

In this paper,we take 31 provinces in China from 2006 to 2015 as samples,and use OLS and GMM estimation methods respectively to verify from an empirical point of view.Productive service industry and manufacturing industry co-agglomeration have positive influence on manufacturing efficiency,Type＂impact.The results show that under other conditions remain unchanged,the degree of synergy between industries has a reasonable range.When the degree of synergy in a region is far below the optimal value,corresponding policies should be adopted to encourage the two to develop together and increase Manufacturing efficiency.On the contrary,some enterprises should be properly relocated so that the degree of synergy can be kept within a reasonable range.
