Evolution of industrial comparative advantages and its driving mechanism of knowledge flow of cities in the Yangtze River Delta under the background of digital economy
Many evolutionary economic geography studies emphasize the role of local capabilities in industrial development based on the path dependence theory.With the rapid development of new-generation information technology and infrastructure such as high-speed rail,the cross-regional flow of knowledge is becoming increasingly common and has a significant impact on regional and industrial evolution.Therefore,in the era of the knowledge economy,the multi-scale knowledge interaction network is crucial to the evolution mechanism of industrial comparative advantages.This study used patent citation big data and other statistical data,such as the total output value of the 2-digit manufacturing industry of 41 cities in the Yangtze River Delta in 2011,2016 and 2021 and the Logit model to analyze the evolution of industrial comparative advantages and its knowledge dynamics.The research found that:1)With the increasingly close intercity knowledge flow network in the Yangtze River Delta,the industries with comparative advantages in cities are becoming increasingly diverse as a whole.2)Under the premise of controlling for local capabilities and other related variables,the evolution of urban industrial comparative advantages is also significantly influenced by the advantageous industries of cities with strong knowledge flows.In other words,a city is more likely to develop its own industrial comparative advantage in the specialized field of another city that has a strong knowledge correlation with it.3)There is a significant knowledge network correlation in the evolution of the industrial comparative advantage structure of cities in the Yangtze River Delta.The stronger the knowledge flows,the higher the similarity of industrial comparative advantage structure between cities.To some extent,this study deepens the understanding of the knowledge dynamics and multi-scale related variety of the evolution of industrial comparative advantages in the digital economy era and helps to provide a theoretical basis for regional innovation and industrial upgrading policies.
