The study discussed the research object of sport social sciences from the perspective of concept orientation and discipline judgment. It states that present literature has wrong statements of logic and practice in the research object of sport social sciences, that is, the wrong descriptions about ＂phenomenon＂ and ＂law＂ as well as the repetitive definition to the naming of the discipline. The study proposes that the research object of sport social sciences should begin with ＂ problems ＂. The research object can be regarded as one important index to judge its discipline attributes as sport social sciences, but not considered as an absolute. The discipline establishment of sport social sciences should involve other indexes besides the research object.
