中国城镇化对经济增长的影响及其区域差异——基于省级面板数据的分析

Influence on the economic growth by urbanization and its regional differences:analysis based on provincial panel data

基于2001-2012年中国省级面板数据,分别研究了人口城镇化和土地城镇化对经济增长的影响及其区域差异,并进一步分析了其内在原因。结果显示:在限定投资、消费、出口和人力资本的条件下,现阶段人口城镇化和土地城镇化均能显著促进经济增长,且人口城镇化对经济增长的影响大于土地城镇化;无论是人口城镇化,还是土地城镇化,其对经济增长的影响都存在明显的区域差异,其中中部地区城镇化对经济增长的促进作用最大,西部地区次之,东部地区最小;我国城镇化的经济增长效应符合"S"型曲线。基于上述结论,提出了相应的对策建议。
