This researsh is aimed to study the relationships among involvements in basketball participation and spectatorship, basketball identification, and willingness to paly and watch basketball for junior high school students. A questionnaire was used in the study including scales of the involvements of basketball participation and spectatorship, basketball identification, and，willingness to participate in and watch basketball games. Questionnaires were distributed to junior high school students who had ever play or watch basketball and 488 were valid with 258 males.The results of regression analyses showed that involvements in basketball participation and spectatorship would cultivate basketball identification and then affected the willingness to participate in and watch the sport. In addition, sport identification partly mediated the relationships between participation involvement and watching intention and between spectatorship involvement and participating intention. The mediating effects were larger than the direct relationships.
