中国城市经济集聚决定因素的实证研究——基于新经济地理学视角

Empirical Research on the Determinants of Agglomeration Economies for Chinese Cities——Based on New Economic Geography Perspective

本文基于新经济地理学关于经济空间集聚的研究视角,采用我国2003—2009年间265个地级及以上城市的面板数据实证检验了城市经济集聚的决定因素。实证研究结果发现,Marshall所强调的三个外部性经济均显著影响我国城市经济集聚,但是劳动力市场外部性和知识外溢却呈现出离心力作用。此外,控制变量的回归系数表明,扩大城市对外开放程度和增加教育投入能促进城市经济集聚,而市场化水平的提高和基础设施的投入则有利于促进城市经济的一体化。

This paper examines the determinants of agglomeration economies for Chinese cities based on the perspective of new economic geography with panel data through 2003-2009.Results indicate that all the three Marshall's theories of agglomeration have significant effect on urban agglomeration.However,the proxies for labor market pooling and knowledge spillovers have negative effect on agglomeration.In addition,the study suggests that economic opening and investment in education promote urban agglomeration,while advances in commercialization and infrastructure construction promote urban economic integration.
