本文将劳动力分为人力资本与普通劳动力两种类型,鉴别了两种类型劳动力流动性特征,并在FE模型(Footloose Entrepreneur Model)基础上,通过引入普通劳动力异质性偏好这一特征,对新经济地理学经典模型进行扩展,分析了劳动力地理集中和地区收入差距之间的关系。模型结论显示:在长期条件下,人力资本流动不仅通过直接效应引起地区收入差距的变化,而且在价格指数效应作用下,普通劳动力同样流入中心区域,流动的规模取决于异质性偏好μ,普通劳动力的地理集中加剧了地区间收入差距。针对上述结论,本文采用2004年和2007年的统计数据进行了实证检验,实证结果发现:普通劳动力集聚与地区收入差距呈现正相关,μ对普通劳动力集中导致地区收入差距变化具有负向作用。
This paper divides the labor force into two types: human capital and common labor force, and distinguishes the two types of labor mobility characteristics. On the basis of the FE model (Footloose Entrepreneur Model), by introducing the feature of the general workforce heterogeneity preference, The classical model of economic geography is extended to analyze the relationship between geographical concentration of labor force and regional income disparity. The results of the model show that under long-term conditions, the flow of human capital not only causes the change of regional income gap through direct effect, but also flows into the central area under the effect of price index effect. The scale of the flow depends on the heterogeneous preference μ, The geographical concentration of labor exacerbated inter-regional income disparity. According to the above conclusions, this paper uses the statistical data of 2004 and 2007 to test the empirical results. The empirical results show that the general labor force agglomeration is positively correlated with the regional income gap, and μ has a negative effect on the general labor force leading to the regional income gap.
