Based on the team performance management theory,considering the academic attribute and development law of humanity and social science,this paper summed up the IMO model of team performance evaluation,distinguished the key performance elements and constructed the performance evaluation index system of AITHSS. The performance evaluation index system,which included three 1-class indexes,fifteen 2-class indexes and fifty 3-class indexes,could be a useful policy tool for strengthening the AITHSS's construction in Chinese universities and the prosperity of philosophy and social science.
