Abstract:

The digital economy is an important driving force for global economic growth, and is playing an important role in accelerating China's economic development and achieving the transformation and upgrading of traditional industries. Manufacturing industry is an important driving force for achieving a new level of real economy, and its digitalization level urgently needs to be comprehensively improved. Promoting the integration of manufacturing and digital economy, have attracted increasing attention from researchers and policymakers.Based on the “statistical classification of digital economy and its core industries (2021)”, the digital product manufacturing industry and the digital technology application industry are selected as representatives of the digital economy industry. At the same time, the manufacturing industry is divided into three categories: resource intensive, labor intensive, and technology intensive. Then, the demand driven model and supply driven model in the input-output method are used to measure the backward and forward association fusion effects of manufacturing industry and digital economy industries in the eight major economic zones of China in 2012, 2015, 2017, and 2018, as well as the fsion ripple effect. Finally, its regional heterogeneity is further explored.The results show that from a national perspective, there are positive backward and forward association fusion effects between digital economy industry and manufacturing industry, and there are obvious differences among industries and departments in the association fusion effect of digital economy industry and manufacturing industry. From the perspective of the eight economic zones, there are significant regional heterogeneities in the backward and forward association fusion effects of digital economy industry and manufacturing industry. In addition, the demand pulling force of digital economy industry to manufacturing industry is generally stronger than the supply driving force, but there are also obvious regional heterogeneities: Among them, the digital economy industry and manufacturing industry in the three coastal economic zones, the middle reaches of the Yellow River and the southwest economic zone are mainly pulled by demand, while the digital product manufacturing industry in the northwest and northeast economic zones and the digital technology application industry and manufacturing industry in the middle reaches of the Yangtze River economic zone are mainly driven by supply. The results of this paper provides useful policy enlightenment for promoting the deep integration of digital economy and substantial economy, accelerating the digital transformation of manufacturing industry, and facilitating the construction of manufacturing power and digital China.

Key words: digital economy industry, manufacturing industry, association fusion effect, regional heterogeneity, input-output method
