内容提要：本文基于中国282个地级行政单位1999-2004年的面板数据，通过使用动态面板数据的计量方法对地区的市场潜能和就业密度与其人均GDP之间的关系进行了实证检验。我们发现，在控制住其他影响因素后，市场潜能和就业密度对地区人均GDP都存在显著为正的影响。同时，无论从绝对弹性，还是标准化弹性来看，市场潜能效应的货币外部性对于地区收入水平都存在着更大的影响。

Abstract:Based on a panel data composed of 282 prefectures data in China from 1999 to 2004, we explore the causes of market potential and employment density externalities on the per capital GDP of these prefectures through a dynamic panel data approach. We find that, after controlling for other factors, both externalities are positive and significant. Moreover, both absolute and standardized elasticities suggest that market potential externality has the stronger impact.
