Impact of urban core areas on county-level human capital in China
Shaping modern human resources and supporting Chinese modernization with high-quality population development is a necessary requirement for promoting high-quality economic development.This article analyzes the spatio-temporal pattern and evolution characteristics of China's total human capital development at the district and county levels,and constructs a bilateral stochastic frontier model to measure the bilateral impact and mechanism of urban core areas on county-level human capital.The research shows that:(1)From 2000 to 2020,China's county(city)human capital continuously increased,but the growth rate slowed down.(2)Overall,urban core areas had a significant driving effect on the improvement of county-level human capital,and the main paths were industrial spillovers and innovation spillovers.(3)The impact of urban core areas on county-level human capital changed from"siphon"to"spillover",raising the actual total human capital of the county from 0.137%below the frontier level in 2000 to 2.657%above the frontier level in 2020,and there was still room for growth in terms of temporal trend.(4)The impact of urban core areas on county-level human capital showed significant spatial differences.In 2020,the development of core areas in first-tier and second-tier cities resulted in 39.110%and 12.966%of county-level actual human capital higher than the frontier level,while the corresponding figure for fourth-tier cities was only 0.006%.(5)There is a significant negative correlation between the net effect of urban core areas on the improvement of county-level human capital and geographical and temporal distance,with the inflection point from positive to negative being around 100 kilometers and 100 minutes.
