Abstract: Promoting the deep integration of China's regional digital industry and manufacturing industry is important point. Based on the new development pattern, on the one hand, starting from the supply side and based on Chinese input-output table in 2017, this paper constructs the indicators of direct integration, indirect integration and integration interaction, and measures the digital industry and digital industry in different provinces in China. The integration effect of the manufacturing industry; on the other hand, starting from the demand side, based on the input-output table of China's provinces in 2017, the direct production induction degree and indirect production induction degree of China's provincial digital industry were constructed, and the provincial Induced dynamics of the digital industry. The research found that: (1) From the perspective of different technology types of manufacturing industries, the digital industry is positively correlated with the technology intensity of the manufacturing industry, that is, the manufacturing industry with higher technological content has a stronger demand for products in the digital sector; In terms of provinces, there are large differences in direct integration and complete integration in different provinces. The integration in the eastern coastal provinces is relatively high, while the degree of integration in the central and western provinces is relatively low, showing a spatial distribution pattern of high in the east and low in the west; There are differences in the pulling and promoting effects of the digital industry in different provinces; (3) From the perspective of inducing power, investment and exports have a greater pulling effect on "communication equipment, computers and other electronic equipment", while consumption and investment have a greater effect on "information transmission", software and information technology services" have a stronger pulling effect. Therefore, it is necessary to promote deep integration of digital industries, narrow the "digital economy gap" between regions, accelerate digital infrastructure construction, and promote the integrated development of China's provincial digital economy and manufacturing industry to empower new quality productivity，and lead high-quality development, and promote regional data factor flow.
