【摘要】：服务业合同密集型的行业特征决定了其集聚行为必然受到契约环境的影响。我们在Acemoglu et al(2007)技术和契约采用模型基础上,对契约环境如何影响服务业集聚的微观作用机制进行了理论探讨。区别于传统文献对行业数据的使用,本文利用2008年全国经济普查服务业企业数据测算了地级市层面四位行业代码下服务业集聚的EG指数,进而对中国243个地级市的服务业集聚情况进行了经验研究,发现在控制了地区特征变量、马歇尔外部性变量以及不可观测的地区差异之后,契约环境对于服务业集聚有显著影响。在用工具变量法克服内生性问题后,上述结论依旧稳健;考虑到极端值存在的情况,我们利用分位数回归的结果依旧支持了以上结论。可见,改善契约环境水平是促进服务业集聚的重要途径。
[Abstract]:The characteristics of service contract-intensive industries determine that their agglomeration behavior is bound to be influenced by the contractual environment. This paper makes a theoretical study on how the contractual environment affects the micro mechanism of service agglomeration, which is different from the use of industry data in traditional literature. In this paper, the EG index of service industry agglomeration under four industry codes at prefectural level and city level is calculated by using the service industry enterprise data of 2008 national economic census, and then the empirical study of service industry agglomeration in 243 prefectural cities in China is carried out. It is found that after controlling regional characteristic variables Marshall externality variables and unobservable regional differences the contract environment has a significant impact on service industry agglomeration. After the instrumental variable method is used to overcome the endogenous problems the above conclusions are still robust. Considering the existence of extreme values, the results of quantile regression still support the above conclusion. Therefore, improving the contractual environment is an important way to promote the agglomeration of service industries.
