Industrial Concentration and Regional Growth: Evidence from the Prefectures
利用区域全要素生产率增长的直接度量，估计动态外部性的影响，发现金融、服务业和批发零售业存在显著动态外部性，而制造业则没有。
In this paper, we estimate the impact of dynamic externalities, using direct measures of total factor productivity (TFP) growth at the regional level. We find that, at the one-digit level, significant dynamic externalities exist for the finance, services, and wholesale and retail trade industries, but-contrary to the findings of most previous research-these externalities do not exist for the manufacturing industry. © 2002 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
