Combined with the research of new quality productivity, this paper analyzes the connotation of computing resources and its role in digital industrialization and industrial digitization, and demonstrates the relationship between computing resources and various elements of digital economy through the combination of qualitative analysis and quantitative model, and evaluates its economic effect. On the basis of the qualitative discussion of computing power resources as the new quality productivity, the gray correlation method and the improved Cobb-Douglas production function are used to quantitatively evaluate the correlation between computing power resources and the development of digital economy. Data analysis shows that there is a significant positive correlation between computing power resources and digital economy, two important aspects of digital industrialization and industrial digitalization, and computing power is the key factor to promote the development of digital economy. This paper puts forward the elements of computing force resources and its core role in the digital economy, empirical analysis calculates the computing force resources to the development of digital economy, studied the computing force resources in the process of digital industrialization and digital mechanism, and put forward to strengthen the construction of computing force resources, promote the development of green computing force, support technology innovation and talent training and other specific Suggestions, promote the development of digital economy in high quality track.
