在经济集聚形成的多种机制中,劳动力要素的流动无疑是经济集聚最重要的因素。在企业生产函数中引入外部效应参数,将城市内部空间结构整合到模型框架中,使模型更加接近现实。本文模型的函数解析与数值模拟表明,劳动力流动引致前后向联系与循环累积效应的＂金融外部性＂和马歇尔外部性,对于经济集聚具有明显的正向促进效应。但随着城市人口大量集聚,企业生产负外部性、劳动力拥挤成本等分散力量会降低经济集聚的程度。

Labor flow is the most important factor among all mechanisms that forms the economic agglomeration. Externality parameter is introduced into the enterprise production function and internal space and structure of the city are interated into the model framework, making the model closer to reality. The function parsing and numerical simulation of the model in this article indicate that labor flow can causes forward and backward linkage and circulation and accum~ated effect of finnacial externality and Marshallian externality, which have positive promoting effect on economic agglomeration. However, with the large population gathering into cities, fragmenting forces like the negative externality of the enterprise production and the labor congestion cost will decrease economic agglomeration.
