工业集聚对中国城市利用外资的影响——基于城镇化门槛模型的实证研究

The Impact of Industrial Agglomeration on Utilization of Foreign Capital in China's Urban Areas:Evidence From Urbanization Threshold Model

文章在阐述各城镇化阶段工业集聚影响城市利用外资机制的基础上,构建了一个含城镇化门槛效应的FDI区位选择模型,运用2003~2013年间中国283个地级以上城市面板数据进行检验。研究发现,工业集聚影响城市外资的城镇化阶段性特征较为明显,且以估计的36%城镇化率为门槛值,该影响会呈现"倒U型"变化轨迹。分组回归结果表明,在较低城镇化阶段,由适度工业集聚产生的规模经济和技术溢出效应等正外部性对城市利用外资有着正向作用;而在较高城镇化阶段,由过度工业集聚产生的拥挤成本等负外部性则会对城市利用外资形成抑制作用。

On the basis of explaining mechanism for the impact of industrial agglomeration on utilization of foreign capital at each stage of urbanization,this paper builds a FDI location choice model with urbanization threshold effect,and tests by using panel data of283 prefecture-level cities between 2003 and 2013. Our findings include: the stage characteristics of urbanization for the impact of industrial agglomeration on utilization of foreign capital is obvious,and shows the inverted ' U' type trajectory. The group regression results show that,the positive externalities such as economic scale and technology spillover effect produced by moderate Industrial agglomeration have positive effect on utilization of foreign capital in urban areas at lower stage of urbanization. the negative externality such as congestion cost produced by excessive industrial agglomeration will cause the inhibition of utilization of foreign capital in urban areas at higher stage of urbanization.
