外来人口社会融合与中国城市创新

Social Integration of Migrant Population and Urban Innovation in China

构建社会融合综合指标以及经济、心理、行为、身份各个融合分指标,建立联立方程研究外来人口社会融合对城市创新的影响。结果表明:社会融合和城镇化水平的提升并没有提高城市创新能力,只有建立在社会融合基础上的城镇化才能促进城市创新水平的提升;经济融合、社会融合、文化和行为融合并没有带来城市创新能力的提升,脱离社会融合的城镇化水平对城市创新的影响为负,但城镇化和社会融合四个维度的交互项对城市创新水平的影响为正;人力资本水平和城市规模以及两个变量与社会融合的交互项都有助于提升城市创新水平,说明在相同的社会融合水平下,人力资本水平越高的群体对城市创新能力的影响越大;与中小城市相比,在特大和超大城市中社会融合水平的提升对城市创新能力的影响更大。

By constructing a comprehensive index of social integration and sub-indicators of economic,psychological behavioral and identity integration,establishing simultaneous equations,this paper studies the impact of social integration of migrant population on urban innovation.The results show that the improvement of social integration and urbanization do not improve urban innovation ability,only urbanization based on social integration can promote urban innovation.Economic,social,cultural and behavioral integration have not brought out the improvement of urban innovative ability,and the urbanization level separated from social integration has a negative impact on urban innovation.However,the interaction of urbanization and four-dimensional social integration has a positive impact on the level of urban innovation.The level of human capital and city size,as well as the interaction between the two variables and social integration,are all conducive to improving the level of urban innovation,which indicates that at the same level of social integration,groups with a higher level of human capital have a greater impact on urban innovation ability.At the same time,compared with small and medium-sized cities,the improvement of social integration in mega-cities and super-cities has a greater impact on urban innovation ability.
