摘要
本文在分析我国区域创新与人口迁移内在联系的基础上，建立了联立方程模型，运用省际面板数据和三阶段最小二乘法对两者之间的内生性问题进行实证估计。结果发现，人口迁移与区域创新存在双向因果关系，人口迁入通过产生人力资本积累和知识溢出效应对区域创新有显著的正效应，区域创新水平的提升反过来能产生“拉力”作用从而提高区域人口迁入率，并且该结果对于模型的不同设定具有稳健性。
Abstract
Based on the analysis of the interrelationship between China’s regional innovation and population migration,we construct a simultaneous equations model to investigate the endogeneity problem between them ,using provincial panel data and three stage least squares. The empirical results indicate that there is a bilateral causality relationship between population migration and regional innovation, which means that human capital spillovers and knowledge spillovers brought by the popu-lation migration have a significant effect on promoting regional innovation and the promotion of regional innovation ,in turn,can produce a “pull”effect so as to improve regional immigration rate. And the results are robust to different model specifications.
