Spatio-temporal coupling pattern and its influencing factors of digital economy,tourism economy and new urbanization:A case study of Yangtze River Delta region
Digital economy,tourism economy and new urbanization are the core driving forces for building a new pattern of regional high-quality development.It is of great theoretical value and practical significance to explore the coupling coordination relationship and influence mechanism among them(DTU system).However,a review of existing studies shows that most relevant literatures on digital economy,tourism economy and new urbanization analyze the relationship between the two,while few literatures include the three into the same framework for research.This is not only not conducive to the systematic clarification of the integrated development relationship between digital economy,tourism economy and new urbanization,but also not conducive to the systematic construction of a strategic system for the economic and social integration development of the Yangtze River Delta region.In view of this,based on the panel data of 41 cities in the Yangtze River Delta region from 2011 to 2020,this paper uses entropy method,coupling coordination degree model,GTWR model,Geodetector and other methods to measure and evaluate the spatio-temporal evolution of the development level of each subsystem of DTU and the coupling coordination degree and its factors of DTU.The results show that:(1)The digital economy and new urbanization in the Yangtze River Delta are increasing year by year,the tourism economy grew steadily from 2011 to 2019,but was hit by public health emergencies in 2020.The growth poles of digital economy is in Shanghai,Hangzhou and Nanjing,and the growth poles of new urbanization is in Shanghai and Nanjing,while the growth poles of tourism economy is in Shanghai and Hangzhou.(2)The coupling coordination degree of DTU system in the Yangtze River Delta region transits from the mildly disordered stage to the verge of disordered stage,and presents a"core-edge"spatial disequilibrium pattern,and forms a spatial distribution feature of"high in the southeast and low in the northwest".Shanghai,Hangzhou,Ningbo,Nanjing,Suzhou,Wuxi,Hefei have a relatively high degree of coupling coordination.(3)The coupling coordination degree of DTU system in the Yangtze River Delta region is the result of the comprehensive effect of 7 factors in the categories of nature,market and policy.Each factor has strong spatial and temporal heterogeneity,and the two-factor interaction is stronger than the single factor.Among the seven factors,tourism market attention,night economy and air temperature have a positive promoting effect and the average influence degree is strong,and the average interaction between terrain and tourism market attention is the strongest.This study not only helps to clarify the coupling coordination mechanism between digital economy,tourism economy and new urbanization,but also can provide reference for high-quality economic and social development in relevant regions.
