Technology Finance Policy and Urban Air Quality——Quasi-Natural Experiment Based on the Pilot Policy of Combining Science and Technology with Finance
Innovation is the first driving force of urban development,and green development is the inevitable goal of urban construc-tion.Technological and financial policies contribute to innovative development through financial means,which are of great signifi-cance to urban green development.Based on the panel data of 284 Cities in China from 2004 to 2020,this paper uses the multi-stage differential difference method to evaluate the impact of the pilot policy of combining science and technology on urban air pol-lution in a quasi-natural experiment.The results are as follows.(1)The pilot policy significantly inhibited the emission of sulfur di-oxide and industrial smoke dust,and the inhibition effect showed an increasing trend with the continuous promotion of the policy.(2)The mechanism study shows that the pilot policy of combining science and finance can reduce urban air pollution through the dual path of improving regional green technology innovation level and promoting industrial structure upgrading.(3)The inhibitory effect of technology and finance policies on air pollution varies depending on the geographical location,population size,technology investment,and financial development level of cities.It is suggested that the construction of regional technology and finance sys-tems should be strengthened based on the different conditions of different regions,and governance of technology and finance should be improved to promote the development of technology enterprises.The government should take the path of green development,at-tach importance to technological innovation and advance,accelerate the environmentally friendly transformation of traditional in-dustries.
