企业单独设立总部机构,是出于追求总部经济效益的目的。而不同种类企业总部的大量积聚现象,则表明总部经济的集聚具有内生动力机制。本文通过建立企业利润随总部集聚规模变化的数理模型,在归纳总部经济效应的基础上,证明了生产性服务业和高端服务业两类总部集聚的微观动力机制是内生存在的;探讨了内生的集聚动力存在的主要条件,暨总部集聚尚未引起集聚区地租的快速大幅增长,以及经济周期处于上升阶段;文章最后部分则运用相关研究成果简单的分析了芝加哥与上海的总部集聚发展情况。 The establishment of a headquarter in a separate company is for the purpose of pursuing the economic benefits of the headquarters. The large accumulation of different types of corporate headquarters shows that the headquarters economy has an endogenous dynamic mechanism. Based on the mathematical model of corporate profits changing with the size of headquarters agglomeration, this paper proves that the micro dynamic mechanism of agglomeration of producer services and high-end service industries is endogenous, The main conditions for the existence of agglomeration motivation and the headquarters agglomeration have not yet caused the rapid and sharp growth of rents in the agglomeration area and the economic cycle is on the rise. The last part of the article uses the relevant research results to simply analyze the headquarters agglomeration development in Chicago and Shanghai.
