Abstract: The research found that Shanxi province did not suffer from bandits and robbers in the regime of Beiyang Government due to Shanxi's police reform.In the 1910s,Beiyang Government launched a national police reform so as to create and maintain a stable society.Under the leadership of Yan Xishan,Shanxi Provincial government implemented a province-wide police reform with Shanxi characteristics which consisted of three vital parts:the strict police administration system,the police training center,and the police wage system.This reform expanded and reinforced the police's involvement into the administration at different levels so as to extend the governmental control to the grassroots units such as villages.However,this police reform did not achieve the anticipated goals due to the bureaucracy and endless internal strife and other social issues.

Key words: The Republic of China, Yan Xishan, Shanxi Police, police reform
