京沪高铁对沿线城市地区间溢出效应的研究——基于2005～2013年地级市面板数据

基于2005年～2013年47个地级行政单元的夜间灯光数据和其他社会经济数据,分析京沪高铁的开通对沿线地区的经济影响。研究结果表明,相对于相邻非京沪高铁城市,京沪高铁显著地促进了所在城市的经济增长,这些高铁城市的经济增长也带动了其他相邻城市的经济发展。同时,京沪高铁的开通也显著地促进了京沪高铁经济带的地区间溢出效应。此外,相对经济水平较低的城市,京沪高铁的建成对经济发达城市的促进作用更为明显。这说明随着京沪高铁的开通,经济扩散和经济集聚是同时并存和发展的。研究结果还表明,在此期间,人口集聚是促进京沪高铁经济带发展最重要的因素,其余依次是投资和出口。投资和人口集聚因素对整个经济带的经济促进作用在增强,而出口因素的作用在下降。
