What is the meaning of the Chinese word translated to English as "sincerity"
The original word for the English translation sincerity is: 诚信.



I believe this is the exact original text from the English you quoted above:


  加强公务员诚信管理和教育。建立公务员诚信档案，依法依规将公务员个人有关事项报告、廉政记录、年度考核结果、相关违法违纪违约行为等信用信息纳入档案，将公务员诚信记录作为干部考核、任用和奖惩的重要依据。深入开展公务员诚信、守法和道德教育，加强法律知识和信用知识学习，编制公务员诚信手册，增强公务员法律和诚信意识，建立一支守法守信、高效廉洁的公务员队伍。




Sincerity records are known as: 诚信档案.
