Abstract: Developing the digital economy is an important strategic choice to achieve a new development pattern. Government procurement policies can work together from both supply and demand sides to provide strong support for the development of the digital economy, thereby achieving industrial structure upgrading. This paper makes use of the data of government procurement constructed with the micro governmentalprocurement order information to analyze the mechanism and specific effects of government procurement supporting industrial structure upgrading. The findings show that government procurement demand can directly affect digitalized governance, driving digital industrialization and industrial digitization, and thus have a positive guiding effect on industrial structure upgrading, especially on the rationalization of industrial structure. Further research has found that the higher the degree of focus on the urban governancelevel, the urban service level, the urban basic researches, and the scientific and technological talents, the more significant the promoting effect of government procurement demand on industrial structure upgrading. The stronger the entrepreneurs’ innovativespirit, the entrepreneurial spirit, and the innovative vitality of enterprises, the more obvious the driving effect of government procurement demand on industrial structure upgrading. Therefore, it is necessary to collaborate government procurement policies with digital industry development strategies to effectively leverage the “targeted” role of government procurement policies,improve urban service level and governance level to effectively leverage the role of government procurement as a “booster” for industrial structure upgrading, and increase the support of government procurement for the basic researches to effectively leverage the “fusion” role of basic research innovation in upgrading industrial structure.
