| Xi Jinping pointed out that science and technology are the weapon of the country,the country depends on it to be strong,the enterprise depends on it to win,and the people’s life depends on it,and scientific and technological innovation is the strategic support for improving social productivity and comprehensive national strength."Only merit can be accomplished,and business is broad."All scientific and technological innovation activities are made by human beings.To build China into a world leader in science and technology,it is essential to build a large,well-structured and well-qualified contingent of innovative personnel to stimulate the innovation vitality and potential of all types of personnel.There are many factors that affect the concentration of innovative talents,and the livability of a city is an important indicator to reflect the attraction of talents.By improving the livable degree of a city,it can attract talents to gather and then realize the improvement of the city’s innovation ability.So this paper puts forward the following research questions:The impact of city livability improvement on city innovation;The influence path of urban livability on urban innovation under the agglomeration of human capital;Regional differences in the mediating effect of human capital in eastern central and western cities.Focusing on the issue of "the impact of urban livability on urban innovation",after combing the literature,it is found that from the research level,regional data were used;from the perspective of research depth,most of them focus on the calculation of coupling degree between the two.Although the internal conduction mechanism of theoretical analysis,but lack of transmission mechanism test.Therefore,this paper refines the research object,deepens the research degree,uses panel data of 35 large and medium-sized cities from 2005 to 2019 to explore the impact path of livability on innovation at the city level from the perspective of human capital agglomeration.Firstly,the livability index system was constructed,and the entropy method with time variable was used to accurately describe the livability level of each city.It was concluded that the livability of eastern,central and western cities was significantly different after being divided into three economic zones,paving the background for the heterogeneity of the mediation effect.Secondly,with the help of the mediating effect model,this paper explores the effect path of urban livability on urban innovation when human capital is used as the intermediary.Finally,based on the differences of livability,the regional differences of human capital mediation effect are verified.The main conclusions of this paper are as follows:(1)With the development of economy and society,the livability of target cities has been improved,but based on objective location conditions,the extent of improvement is not the same.In general,the livability of regional central cities has been improved more obviously than that of surrounding cities.(2)The least square dummy variable(LSDV)method was used to estimate the impact of urban livability on innovation.The results show that there is a significant positive correlation between livability and innovation,and livability positively promotes innovation in ecological,social and cultural environments.(3)Human capital is the key factor of urban innovation,and the proportion of the mediation effect is 7.24%,which significantly affects the path of the effect of urban livability on urban innovation at the level of 1%.(4)Human capital in each region plays a part of the mediating role,but there is heterogeneity.The relative proportion of the mediating effect of human capital in the eastern,western and western regions respectively is 13.8%,6.27%and 32.41%. |
