本文通过构建一个两区域-两部门-两要素的地方政府公共服务空间溢出理论模型,分析了私人产品替代弹性、交易成本变化对公共服务空间外溢和要素流动的影响。运用我国30个省份2001~2010年的面板数据进行了实证分析,发现地方政府间公共服务呈现出日益明显的正自相关关系和空间依赖性,验证了省际间公共服务的空间溢出效应。 This paper analyzes the effect of substitution elasticity and transaction cost of private products on the spillover of public services and the flow of factors by constructing a two-area-two-sector-two theoretical model of spillover of public services by local governments. Using the panel data of 30 provinces in China from 2001 to 2010, we find that the public services in local governments are showing increasingly positive autocorrelation and spatial dependence, which verifies the spillover effect of public services across provinces.
