The digital exhibition economy is a process that enables and reshapes the entire chain of traditional exhibition services through the full use of modern information technology，so as to realize the process of reengineering the industrial chain and upgrading the value chain. COVID-19 has forced the convention and exhibition industry to accelerate the digitalization process. Actively deploying cloud conventions and exhibitions has become a new trend in major cities，and the digital support technology for the convention and exhibition economy has become more complete. In the post-COVID-19 era，Beijing is facing a critical period of transforming the old and new kinetic energy of the exhibition economy. Beijing’s modern service industry foundation，digital economy resource endowment，new infrastructure construction speed and other conditions are conducive to shaping the new advantages of the exhibition economy development in Beijing. However，there are still some problems，such as unclear mode of digital exhibition，weak informatization foundation of exhibition industry，lack of digital skills of exhibition personnel，and imperfect investment and financing mechanism of digital exhibition. In the future，we need to promote the transformation and development of Beijing’s Convention and exhibition economy by consolidating the digital exhibition infrastructure，cultivating the digital exhibition enterprise cluster，building a public platform for digital transformation，forming a digital industrial ecology，and strengthening the digital exhibition talent team.
