In 2021，the Rule of Law Index Innovation Project Team of the Institute of Law of the Chinese Academy of Social Sciences evaluated the police transparency of 73 public security organs from the perspective of public security organs’ website information disclosure，which was also the fifth year of the evaluation of China’s police transparency index. The evaluation results showed that the public security organs continued to strengthen the friendliness of website construction，enhanced the transparency of administrative non-tax incomes，promoted the integrated development of convenient interactive services，unified the information disclosure platform，continuously enhanced the awareness of data openness，and constantly improved the three-dimensional public security image. However，there were still some problems such as insufficient disclosure of normative documents，lack of construction standards of open law enforcement platform，weak service function of micro-platform and insufficient data openness. Accordingly，in the future，Ministry of Public Security should improve the design of the Publicity of Policing system while implementing the new Administrative Punishment Law，establish a national unified public security law enforcement information publicity platform，promote the construction of the mobile terminal of police service platform to highlight service functions，and continuously promote the public security organs to open data.
