As a new sector of the national economy, digital economy, with its data elements and digital technology, has profoundly changed the real economy and social life, and is reshaping the new pattern of social production, exchange, distribution and consumption. The government and the market, as the important promoters of the development of digital economy, also exist some failures during this period. Therefore, it is necessary to properly handle the relationship between the market and the government, and on the basis of giving full play to the decisive role of the market mechanism, actively give play to the role of the government, and build a long-term development mechanism organically coupled with “effective market + promising government”. Only in this way can we promote the sustainable and healthy development of the digital economy and enable the high-quality development of the real economy.
