Abstract:

This paper uses PVAR, coupling coordination and Moran index model to conduct an empirical study on the dynamic coupling coordination between digital transformation and high-quality development of manufacturing industry in China during 2015-2019. The results show that the overall development level of the two systems in China shows a fluctuating upward trend, however, the differences among the eastern, central and western regions are obvious. In terms of interaction, digital transformation of manufacturing industry plays a more significant role in promoting high-quality development. The overall coupling coordination degree of the two systems in China shows a steady increase trend, decreasing gradually from the east to the west. In the coupling coordination of spatial correlation relations, the eastern region is characterized by "high-high" aggregation, the central region is not significant, and the western region is characterized by "low-low" aggregation. Therefore, it is of necessity to give further play to the driving role of the eastern region to the central and western regions, and improve the coupling coordination degree of the two systems according to local conditions

Key words: manufacturing digital transformation, high-quality development of manufacturing industry, coupling coordination, digital China, digital economy
