At present, the main obstacle to China's high-quality economic development is the structural contradiction, which is the structure mismatch of supply and demand. Digital technology is changing every day, and its application potential is bursting into full release.

By expanding traditional demand, enriching emerging demand, and promoting demand upgrading, digital economy will drive an appropriate expansion of total demand. To deepen China's supply and demand structure reform, we should strengthen top-level design, give full play to the innovative of the digital economy, consolidate the foundation for the development of digital industrialization, deepen the integration of the digitaleconomyin various fields, and build an open and inclusive environment.
