From the perspective of sociology, the analysis is not to expound behavior of leisure activities such as recreation, sports, games, sightseeing, etc. by classifying it, but to understand its theoretical basis and structure. Meanwhile, the research discusses issues of society today, which influence the participation of leisure activity. Moreover, it shows that the participation behavior of leisure activity is a process, which amends societal structure constantly, and its content is a result of interaction between individual and societal structure, besides the individual participation motives and its expected profits. Therefore, it is a socialized and continuous constructive process. Basically, leisure activity itself is a complicated phenomenon, and also a combination of daily life. Hence, a simplex theory or method can’t define it thoroughly. But through a complete research, we can figure out the essential factor of its interior structure. Also, the social factors, which influence the participation of leisure activity, are as complicated as leisure activity itself. And according to the societal phenomenon today, the issues of social stratum, life style, and social change influence most.
