This article analyzes the course，innovations，and problems of nationwide optimization of government services from 2018 to 2020，focusing on the five-level government reforms of the central government，provinces，cities，counties，and townships，and clarifying each local government’s efforts to optimize the government service environment reform work. The current optimization of the government service environment requires the coordinated advancement of laws，systems，personnel，technology，and supporting mechanisms. The use of big data and “Internet + government services” is the focus of the nationwide optimization of government service reforms at this stage. It should be noted that in the current process of optimizing government services，there are still problems such as “Internet + government services” that need to be improved，online and offline service supply is difficult to integrate，civil servants’ ability training is backward，and administrative approval is not standardized. The focus of future reforms should be on promoting the comprehensive use of various policy tools，promoting the organic integration of online and offline government affairs，strengthening the capacity building of government officials，and further improving the standardization of administrative approval.
