要素空间集聚、制度质量对全要素生产率的影响研究

要素空间集聚影响空间资源配置效率,制度质量影响要素积累效率,两者的综合作用影响全要素生产率.本文通过量化人力资本、物质资本、劳动力和创新要素集聚,构建要素空间集聚指标,运用中国1997-2016年的省域面板数据,采用空间动态面板数据(SDPD)模型实证检验了要素空间集聚、制度质量对全要素生产率的影响.研究表明:要素空间集聚对全要素生产率增长的作用表现出阈值效应,东、中、西和东北部地区的集聚中心分别是广东、湖北、四川以及辽宁;要素空间集聚和制度质量对全要素生产率增长产生正向作用,两者存在互补的影响关系.研究还发现:东中西和东北地区的要素空间集聚、制度质量对全要素生产率的影响存在明显差异,经济高速增长阶段的要素空间集聚、制度质量对全要素生产率的影响效应最显著.

The impact of elements spatial agglomeration and institutional quality to TFP

The agglomeration of spatial elements affects the efficiency of spatial resource allocation and the quality of the system influences the efficiency of factor accumulation. The combined effects of the two above influence TFP. This paper quantifies the aggregation of human capital, material capital, labor force and innovative factors to build an elements spatial clustering index using the provincial panel data of China from 1997 to 2016. The spatial dynamic panel data (SDPD) model is used to empirically test the effect of factor spatial agglomeration and institutional quality on total factor productivity. The results show that elements spatial agglomeration exhibits threshold effect on the TFP growth. The agglomeration center of East, Central, West and Northeast are Guangdong, Hubei, Sichuan and Liaoning respectively. Elements spatial agglomeration and institutional quality have a positive effect on the growth of total factor productivity. There is a complementary relationship between the two. This study also finds that there exist significant differences of the impact of elements spatial agglomeration and institutional quality to TFP in all the regions. And the effects of elements spatial agglomeration and institutional quality to TFP in the economic growth phase are most notable.
