The research aims at investigating the correlation degree between watching intention and satisfaction of the spectators watching 2016 National City Football League on the field. The research applies the method of questionnaire survey which was conducted by the researchers at the stadiums where National City Football League was held, such as Kaohsiung National Stadium, Taipei Stadium, etc., from April. 9th to 23st in 2016. Totally 300 questionnaires were sent out and 288 valid ones were retrieved. The recovery rate of the valid questionnaires was about 96%. The researchers conducted the research on the correlation degree between watching intention and satisfaction of the spectators by using structural equation modeling (SEM). The research findings show that the model of this research is positive definite and in good adaption, and watching intention and satisfaction of the spectators watching 2016 National City Football League on the field have a significant correlation. Their correlation coefficient is 0.86, which is so highly correlated that the assumption of this research is confirmed. Researchers believe that the high correlation may possibly due to the fact that the more satisfaction spectators get from the event itself and its activities, hardware and software facilities in the surrounding area, the higher satisfaction the spectators get, which will increase their willingness to pay the entrance fee again. The improvement of watching intention shows that the spectators also expect this sports event very much. If their expectation is satisfied positively, their satisfaction will be improved accordingly. Based on the research conclusions, researchers put forward three proposals listed as follows. First, improve the parking flow line and the transportation transit services. Second, strengthen the live atmosphere and create high tension competition environment. Third, set reasonable fare and launch relevant promotional campaigns.
