产业集聚促进区域经济增长探析

Industrial Agglomeration,Factor Allocation and Regional Economic Growth

产业集聚不仅可以直接影响经济增长,还可以通过影响要素配置效率对经济增长发挥作用。我国资源要素配置呈现区域行业分布结构性差异,存在一定程度的扭曲,阻碍了地区经济增长。构造产业集聚水平、劳动力和资本要素扭曲程度指标,运用SDM模型对2004—2018年28个省(自治区)制造业中的20个细分行业的面板数据进行空间计量分析,结果显示:将产业集聚与资本扭曲和劳动力扭曲分别进行估计时,产业集聚可以较为显著地促进本地区经济增长但不能通过改善本地区资本扭曲或劳动力扭曲来提升本地区经济增长,产业集聚会抑制周边地区经济增长,但可以通过改善资本扭曲或者劳动力扭曲的手段来促进周边地区经济增长;把产业集聚与资本扭曲和劳动力扭曲的交叉项同时放进模型时,从整体上看,产业集聚可以同时改善资本扭曲和劳动力扭曲来提高地区经济增长。

Industrial agglomeration can not only directly affect economic growth,but also play a role in economic growth by affecting the efficiency of factor allocation.China's resource factor allocation presents structural differences in regional industry distribution,and there is a certain degree of distortion,which hinders regional economic growth.This paper constructs the indicators of industrial agglomeration level,labor and capital factor distortion degree,and uses SDM model to analyze the panel data of 20 sub sectors of manufacturing industry in 28 provinces from 2004 to 2018.The results show that when industrial agglomeration is estimated separately from capital distortion and labor distortion,industrial agglomeration can significantly promote the regional economic growth,but it can not By improving the local capital distortion or labor distortion to improve the regional economic growth,industrial agglomeration can inhibit the economic growth of surrounding areas,but it can promote the economic growth of surrounding areas by improving the capital distortion or labor distortion.When the cross terms of industrial agglomeration,capital distortion and labor distortion are put into the model at the same time,on the whole,industrial agglomeration can promote the economic growth of surrounding areas At the same time,improve capital distortion and labor distortion to improve regional economic growth.
