Abstract：Based on panel data of 282 prefectures in China from 1999 to 2004; we explore the relationship between market potential, employment density and per capita GDP by using a dynamic panel data approach. It is found that the externalities arising from market potential and employment density have a positive and significant effect on local income. Moreover, both absolute and standardized elasticity of market potential externalities are pronounced, which suggests that market potential has a greater impact on regional disparity.
