外来劳动力技能多样性对城乡融合的影响——基于长江经济带县域的实证研究

Impacts of the Diversity of Migrant Labor Skills on Urban-Rural Integration:Empirical Evidence Based on the Counties in the Yangtze River Economic Belt

利用熵值法测度长江经济带县域城乡融合发展水平,并利用全国流动人口动态监测调查数据构建外来劳动力技能多样性指标,实证检验外来劳动力技能多样性对县域城乡融合发展的影响效应和机制。研究发现:长江经济带县域城乡融合发展水平呈波动上升趋势,且呈现下游县域>上游县域>中游县域的空间分异格局;外来劳动力技能多样性能显著促进县域城乡融合,但影响效应存在区域异质性和流入方向异质性,在下游县域、城市群县域中,外来劳动力技能多样性促进县域城乡融合发展的效应更为明显,农村外来劳动力技能多样性的效应更强;机制检验表明,外来劳动力技能多样性能加速形成厚劳动力市场,推进农业技术创新,进而促进县域城乡融合。

This paper measures the level of urban-rural integration development in the counties of the Yangtze River Economic Belt by the entropy method,and uses the data from the National Monitoring of Mobility Survey to construct indicators of the diversity of migrant labor skills,then empirically tests the effects and mechanisms of the diversity of migrant labor skills on the development of urban-rural integration in the counties.The study found that:the level of urban-rural integration development in the counties in the Yangtze River Economic Belt shows a fluctuating upward trend and a spatially divergent pattern of downstream counties>upstream counties>midstream counties;the diversity of migrant labor skills can significantly contribute to urban-rural integration in the county,while there is regional heterogeneity in the impact and in the direction of inflow.The effect of the diversity of migrant labor skills in promoting urban-rural integration in counties is more pronounced in downstream counties and in urban cluster counties,and the effect of diversity of migrant labor skill diversity in rural areas is greater.Mechanistic tests reveal that the diversity of migrant labor skills accelerates the formation of a thick labor market,promotes agricultural technology innovation and in turn promotes urban-rural integration in the county.
