The Future of Cities in the"Digital Economy"Era——A Study on the Impact of Internet on the Agglomeration of Producer Services in Chinese Cities
We construct an instrumental variable for the Internet penetration rate using China's"8-horizontal-8-longitudinal"optical cable network to identify the impact of the Internet on the agglomeration of producer services in cities.We find that,(i)the Internet promoted the agglomeration of producer serv-ices to cities with larger population size due to the higher knowledge intensity of large cities;(ii)the Inter-net can strengthen the role of the expansion of manufacturing industry in a city or its surrounding areas in promoting producer services agglomeration in large cities,which in turn promotes the agglomeration of producer services to large cities.
