近年來鐵人三項運動在全球掀起熱潮，不僅吸引成千上萬的運動愛好者投入，更帶動無數商機。有鑑於此，本研究目的為檢測臺灣最大規模的鐵人賽「天利盃2016 宜蘭梅花湖鐵人三項錦標賽」整體經濟效益。以問卷調查法施測，回收有效樣本511 份，並以經濟影響評估法分析產業關聯效果。所得結果指出：消費投入產出投資報酬率達241%，且不論產出、所得或就業效果，皆以「住宿及餐飲業」比例最高。此外，「藝術／娛樂及休閒服務業」亦為核心消費項目之一，而「批發及零售業」相對貢獻度較低。本研究獲得結論為：住宿及餐飲業為經營鐵人三項賽會不可或缺消費選項，亦為其他產業部門發展火車頭，因此未來舉辦賽會應設法延長參賽者的停留時間以增加效益。另可採用多元報名誘因以吸引參賽選手，擴大產出效果。
