摘要
基于2008-2017年全国31个省、自治区和直辖市的面板数据,研究聚集经济、固定资产投资和人力资本水平对经济增长的影响,考虑到聚集经济的内生性问题,用滞后期的城市人口密度作为聚集经济的工具变量,运用面板数据工具变量分位数回归估计方法分析各变量对经济增长的影响。分析结果表明,三个变量都促进经济增长,在不同分位点上,聚集经济和人力资本水平对经济增长的促进作用随分位点的增加而减小,固定资产投资对经济增长的促进作用随分位点的增加缓慢增加。
Based on panel data of 31 provinces,autonomous regions and municipalities across the country from 2008 to 2017,this paper studies the impact of agglomeration economy,fixed asset investment and human capital level on economic growth,taking into account the endogenous problems of the aggregation economy,using lagging urban population density as an instrumental variable of agglomeration economy,using panel data tool variable quantile regression estimation method to analyze the impact of each variable on economic growth.The results show that,all three variables promote economic growth,at different quantiles,the accelerating effect of agglomerated economy and human capital level on economic growth decreases with increasing quantile,while the promotion effect of fixed asset investment on economic growth increases slowly with the increase of quantile.
