集聚与扩散:异质性劳动力和多样化贸易成本的空间经济效应

文章将异质性劳动力及地区内和地区间的多样化贸易成本同时引入空间经济模型,建立了一般均衡模型。分析结果表明,低成本约束的人力资本比高成本约束的普通劳动力流动更容易打破空间经济集聚和扩散的对称均衡,促使产业空间结构稳定地向人力资本丰富的地区集聚。文章还从福利最优化的角度分析了政府对空间经济结构的规划选择,结论显示降低普通劳动力在地区间流动的成本有利于形成分散均衡的经济格局,实现社会公平。

Agglomeration and Dispersion:Spatial Economic Effect of Heterogeneous Labor and Diverse Trade Costs

This paper introduces heterogeneous labor and intra-regional and inter-regional diverse trade costs to spatial economic model and constructs a general equilibrium model.The results indicate that labor flow with low costs can more easily upset the balance between spatial economic agglomeration and dispersion than labor flow with high costs,resulting in industry agglomeration in areas with rich human capital.It also studies governmental choice of spatial economic structure from the angle of welfare optimization and reaches a conclusion that the reduction in inter-regional labor flow costs is beneficial to the formation of a dispersion balance of economic structure and the realization of social fairness.
