Abstract: The deep integration of digital economy or digital technology with the real economy is an inevitable choice for achieving high-quality development of China's economy. By tracing the theoretical basis of "digital real integration", we have reviewed relevant domestic and foreign literature on promoting high-quality economic development through "digital real integration". Research has found that there may be issues in current research such as unclear definition of core concepts, incomplete research system, and insufficient integration between research and practice. Based on this, future research trends are proposed, including introducing the "technology economy" paradigm to define the concept of the digital economy, paying attention to the application of classical theories in the field of the digital economy, and emphasizing the extraction of "Chinese experience" in the development of the digital economy.

Key words: digital economy, real economy, data real fusion, high quality development
