[Purpose] The purpose of this study is to analyze the effect size of the relationship between team identification and their intention to attend sport events and intention to purchase licensed team merchandise using a Meta-analysis. [Methods] To accomplish the purpose of the study, multiple databases were visited (e.g., RISS, KISS, Library of National Assembly) and studies were collected using the keyword of team identification. Through the search process, total of 92 studies were identified, among which 20 studies provided Pearson correlation coefficients between team identification and intention to attend and 13 studies between team identification and intention to purchase licensed team merchandise. The 33 studies were analyzed using Comprehensive a Meta Analysis(CMA) program. The analyses were done using random effect model assuming there were significant heterogeneity among the studies included. [Results] The overall effect size between team identification and intention to attend sport games was .567 and .403 for between team identification and intention to purchase licensed team merchandise, which can be classified as large effect size(Cohen, 2013). Sub-group analyses were done using types of publication(journal article vs. thesis). The results of the sub-group analyses indicated that the effect size differences were statistically insignificant. [Conclusions] As indicated in many previous studies, team identification was found to be a significant predictor of sport consumers’ behaviors. However, future studies need to find the reasons of heterogeneity in effect sizes.
