公共服务、外部性与工业集聚

Public Service,Externalities and Industrial Agglomeration

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。

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 ag- glomeration, and that effect has externalities by preference. The advantages of industrial agglomeration can further enhance by circular cau- sation. It also uses provincial panel data of China from 1999 - 2014 to test the influence of externalities of related variables on industrial ag- glomeration. 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 ag- glomeration has an upward trend.
