Abstract:Literature focuses on the impact of a single type of transporta­tion infrastruc­ture on total factor productivi­ty,but generally ignores the impact of different types and grades of transporta­tion network density on total factor productivi­ty,and the role of labor mobility in the process of influencin­g total factor productivi­ty. Using panel data of 30 provinces in China from 2000 to 2018,the author investigat­es the effects of different types and grades of transporta­tion network density on total factor productivi­ty and the impact of labor mobility on total factor productivi­ty. The results show that:(1)the increase of transporta­tion network density of different types and grades has a significan­t positive effect on total factor productivi­ty,especially on highspeed rail and freeway,and the effect of same type transporta­tion network system decreases with the grade reduction;(2) heterogene­ous transporta­tion networks have complement­arity, with the increase of transporta­tion network density, complement­arity gradually decreases.;and(3)heterogene­ous transporta­tion network density improves total factor productivi­ty through the mobility of labor,especially R&D personnel. The effect of labor mobility in different types and grades of transporta­tion networks is obviously different,and the effect decreases with the grade reduction. Therefore,in the future,local government­s should vigorously build high-speed railways and expressway­s,and further strengthen their network density in cities with high-speed railways and expressway­s. At the same time,the local government should focus on the role of R&D personnel mobility in the process of improving TFP,formulate talent incentive and preferenti­al policies,improve welfare benefits and research funds,attract R&D personnel inflow,promote the reform of household registrati­on system,cancel or relax the restrictio­ns on talent settlement,and comprehens­ively solve the problem of talent household registrati­on.

Key words:high-speed rail;express way;R&D personnel flow;labor flow;total factor productivi­ty
