Data is the primary factor of production in the digital economy, playing a role in promoting the deep integration of the digital economy and the real economy and smoothing the national economic cycle. After entering the circulation system of the real economy, data is rapidly integrated into production, circulation, consumption, distribution, and other links. It optimizes resource allocation, unblocks circulation channels, promotes accurate matching of supply and demand, stimulates emerging demand, and forms a virtuous circle of digital technology application, traditional physical enterprise transformation, and technological innovation. Integrated development is an important feature of the digital economy. Data promotes the integration of factors of production, products, enterprises, industries, and markets, which fosters a circular system with deep integration of the digital economy and the real economy. To promote the deep integration of the digital economy and the real economy, the government and business entities should take measures to improve the circular efficiency of the digital economy and the real economy. These measures include attaching importance to the role of data-driven development, improving data capacity, data development, and utilization in enterprises, exploring diverse circulation models of enterprise data, and creating typical application scenarios and industrial data spaces.
