The purpose of this study was to explore the relationship between fan involvement and spectators' needs for quality sport facilities and services. Several studies have indicated that both facilities and services quality were important factors influencing a spectator's intention to support a team and attend sporting events. This study was based on Wakefield and Sloan's (1996) hypothesized model of Sportscape and Josiam's (1998)Personal Involvement Inventory (PII) This research was conducted during games five and six of the 2003 Chinese Professional Baseball League (CBPL) series using convenience sampling. The sample included 573 participants. Primary findings were: (a) highly involved fans gave higher ratings to atmosphere of the game and stadium access, while fans who were not highly involved gave higher ratings to atmosphere of the game, pricing, and ticketing service. (b) fans of both the home and visiting teams exhibited a similar level of involvement. (c) fans of both home and visiting teams showed no significant difference in their needs for quality facilities and services. (d) spectators from different teams or stadiums had no significant interaction between the factors of quality sport facilities and services. According to the findings of this study, spectators seek high quality sport facilities and services. Therefore, owners of professional baseball teams may create more profit by enhancing the service quality and the physical environment of the stadium to ensure that spectators have an enjoyable trip to the ballpark and a desire to return.
