In order to further deepen the reform to “delegate power，streamline administration and optimize government services”，China’s 2016 government work report for the first time put forward the requirements of comprehensively promoting “Internet + government services”. All regions and departments earnestly implement the relevant requirements of the Party Central Committee and the State Council on the reform of “Internet + government services”，give full play to local and sector advantages，and vigorously explore the practice innovation and model innovation of “Internet + government services”. This article summarizes the reform progress and development effectiveness of the “Internet + government services” carried out by government departments at all levels in China from 2016 to 2020. The study found that the current development of “Internet + government services” faces problems such as imperfect data sharing mechanisms，unbalanced development，and insufficient sense of mass acquisition. In the future，it is necessary to further increase data sharing efforts，innovate service models，and improve overall service quality，so as to provide a solid guarantee for in-depth promotion of the reform to “delegate power，streamline administration and optimize government services”，and constructing service-oriented governments.
