长三角地区经济一体化的经济增长效应

从长三角地区两省一市真实人均GDP增长率的角度,实证检验了地区经济一体化对地区经济增长的影响.实证研究表明,以时间变量衡量的地区一体化在一般意义上能够提高真实人均GDP增长率,其变化轨迹遵循先下降后上升趋势,与长三角地区一体化的现实观察基本吻合.通过考察个体-时刻固定效应模型避免了事件虚拟变量间接衡量一体化的模型设定问题,结果表明以地区贸易、人口流动、服务业发展和政府对经济的参与四个方面衡量的地区一体化,虽然个别变量存在选择偏误和代表性问题,但在总体效应上与促进经济增长的理论预测相一致.

Growth Effects of Yangtze River Delta's Economic Integration

The study tests the effects of regional integration of Yangtze River Delta on its economic growth using the real GDP growth rate per capita panel data.The results show that regional integration in terms of time variable increases the real GDP growth rate per capita following a U-curve trend,consistent with our daily economic observation.Using time and entity fixed effects regression model to avoid the question of model specification,we find that regional integration in terms of foreign and domestic trade,po...
