随着新一代信息技术和高铁等基础设施的快速发展,知识跨域流动越发普遍,并对区域和产业演化产生重要影响.论文利用2011、2016和2021年长三角地区41个城市的专利引证大数据和两位数制造业产值等统计数据,并运用Logit模型等方法对长三角城市产业比较优势演化及其知识流动驱动机制进行分析.研究发现:①随着长三角城际知识流动网络的日趋紧密,城市具有比较优势的行业门类整体上愈加丰富;②知识跨域流动对产业比较优势演化产生显著正向影响,且某城市更容易在强知识关联城市的专业化领域发展自身比较优势;③长三角城市产业比较优势结构演化存在显著的知识网络关联,强知识流动城市间的比较优势结构的相似性更高.研究结果在一定程度上深化了学界对数字经济时代产业比较优势演化的知识动力及其多尺度相关多样性的认识,有助于为区域创新和产业升级政策提供理论依据.
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.
