Research on the Impact of the Establishment of National Big Data Comprehensive Pilot Zone on the Income Gap between Urban and Rural Areas
The article is based on a quasi-natural experiment set up by the national big data comprehensive pilot zone,using panel data from 202 prefecture level cities in China from 2010 to 2019.By constructing a multi-period double difference model,the article empirically analyzes the impact and mechanism of the es-tablishment of the national big data comprehensive pilot zone on the urban-rural income gap.Research has found that the establishment of national big data comprehensive pilot zone can significantly reduce the ur-ban-rural income gap,and this conclusion is still valid after a series of robustness tests.The mechanism test found that accelerating the construction of digital infrastructure and improving the level of urbanization are two important mechanisms for the construction of big data comprehensive pilot zone to narrow the ur-ban-rural income gap.The heterogeneity analysis found that the effect of narrowing the urban-rural income gap in the national big data comprehensive zone is mainly concentrated in the eastern region and low admin-istrative level cities,while there is no significant impact in the central and western regions and high admin-istrative level cities.The research conclusions provide empirical evidence for promoting the development of digital economy to help achieve common prosperity.
