公共服务、外部性与工业集聚

本文在新经济地理学框架内，通过引入政府部门构建了一个空间均衡模型，理论研究表明，公共服务支出的提高可以促进工业集聚，并且受偏好的影响存在外部性，而集聚优势则通过循环累积因果关系进一步扩大。通过使用1999～2014年中国省际面板数据，检验了相关变量对工业集聚所产生的外部性影响，研究发现：公共服务、市场潜能均与工业集聚呈正相关，随着工业集聚程度的提高，公共服务对集聚的影响是递减的，反映了低集聚地区公共服务支出不足的现状，而市场潜能对集聚的影响存在一个上升的趋势。

Public Service,Externalities and Industrial Agglomeration

Based on the framework of New Economic Geography,this paper constructs a spatial equilibrium model which contains the government sector.The theoretical research shows that the increase of public service expenditure has a positive effect on industrial agglomeration,and that effect has externalities by preference.The advantages of industrial agglomeration can further enhance by circular causation.It also uses provincial panel data of China from 1999-2014 to test the influence of externalities of related variables on industrial agglomeration.The empirical results show that:the public service and market potential are positively related to industrial agglomeration.With the increase of industrial agglomeration,the influence of public service on agglomeration has a diminishing effect which reflects the current situation of public service expenditure which is insufficient in low agglomeration areas,and the influence of market potential on agglomeration has an upward trend.
