Measurement and Temporal-Spatial Comparison of the Integration of the Digital Economy and the Real Economy in the Context of New Quality Productivity:Based on the Patent Co-classification Method
The report of the 20th National Congress of the Communist Party of China proposed to accelerate the development of the digital economy,promote the deep integration of the digital and real economies,and create an internationally competitive digital industry cluster.In recent years,with the continuous innovation and widespread application of digital technologies such as big data,cloud computing,the Internet of Things,blockchain,and artificial intelligence,the scale of China's digital economy reached 50.2 trillion yuan in 2022,and the penetration rate of the digital economy into agriculture,industry,and service industries increased to 10.5%,24.0%,and 44.7%,respectively.The integration of the digital and real economies can improve the production efficiency of traditional industries and promote industrial transformation and upgrading.It also spawns new industries,new models,and new kinetic energy,thereby forming new driving forces for economic development.Promoting the deep integration of the digital and real economies has become a key point and important support for developing new quality productive forces,building a modern industrial system,and promoting high-quality economic development.Under the guidance of policies,the practical integration of the digital and real economies has been carried out in-depth and achieved remarkable results.However,existing research has some limitations in measuring the integration of the digital and real economies,making the calculation results unable to fully or timely reflect latest practices.Therefore,based on the perspective of technology-driven industrial integration,this study uses China's patent application data from 2012 to 2021 and adopts the patent co-classification analysis method to measure the integration level of the digital and real economies.It also examines the integration characteristics of the digital and real economies from three dimensions—time,industry,and region.In the extended analysis,the social network analysis method was used to explore the network characteristics and evolutionary trends of China's digital-real integration network.The main findings are as follows.First,the integration level of the digital and real economies generally experienced an upward trend.Second,from an industrial perspective,the integration has unbalanced characteristics.In terms of the real industries,the integration level of the service and digital industries is the highest,followed by manufacturing,construction,and other industries,and the integration level of the agriculture and digital industries is the lowest.In terms of the digital industry,the integration level of the digital product service industry and the real industry is the highest,which has begun to transform from the field of product manufacturing to the field of factor-driven and technology application.Third,from a regional perspective,the integration level of the digital and real economies is divided among the four major sectors.This characteristic also exists among the 19 urban agglomerations and cities of different sizes.Fourth,the social network analysis results indicate that the digital-real integration network has obvious core-edge structural characteristics.The network density has increased from 0.20 to 0.25,and there is still a lot of room for improvement in industrial integration.This study has three aspects of contribution.First,it optimizes the measurement method for the integration of the digital and real economies.This study forms the basic idea of measuring the integration of the digital and real economies from the perspective of technology-driven industrial integration.Second,the dimensions of the measurement method are more diverse.It measures the integration level of the four-digit industries,which can provide three-dimensional integration information of time,region,and industry.Finally,based on the calculation results,it conducts a temporal-spatial comparative analysis of the integration situation.The analysis conclusions provide a basis for proposing policies to promote the deep integration of the digital and real economies and develop new quality productive forces.
