The Impact of Air-Rail Intermodality on Urban Economic Development—Theoretical Analysis and Evidence from the Yangtze River Delta Region
Air-rail intermodality(ARI)is a burgeoning mode of transportation organization in China,and its impact on urban economic development determines the future guidelines and development of ARI,this paper discusses the economic effects of ARI from the perspectives of theoretical exploration and empirical analysis.Firstly,we build a consumer utility function by the light of the Dimond Model and propose research hypotheses through general equilibrium analysis.Secondly,based on the panel data of 33 cities in China's Yangtze River Delta region,we select the city's GDP growth rate and industrial structure as indicators to measure economic development,as well as the continuous difference-in-difference(DID)method is adopted to investigate the impact of ARI entry on urban economic development.Thirdly,we use a direct effect model and a heterogeneous DID model to examine the intrinsic mechanism of the opening of ARI on urban economic development.Our results show that the entry of ARI has a significant positive impact on the GDP growth rate of cities in the Yangtze River Delta region and is positively associated with the adjustment and upgrading of the local industrial structure.In addition,the mechanism by which ARI influences economic development is that it can significantly stimulate employment and technical innovation,thereby promoting urban economic development.
