近年手機遊戲產業發展迅速，不論是在全球或是台灣皆呈現高潛力的發展趨勢，手機遊戲有望在不久的將來成為遊戲界營收佔比最高的類別。相應著這樣的潮流，對手機遊戲的相關研究也跟著大量出現，研究題材如遊戲內容品質、平台營造以及營利模式等等，均為手機遊戲的開發有諸多貢獻。但是，儘管手機遊戲的研究正在興起，其走向仍以遊戲本質為主，鮮少有針對手遊玩家使用心態的研究，更遑論探討其與消費行為之間的關聯。 為了解決這樣的理論空缺，本研究欲以玩家的遊玩動機與遊戲特質偏好，結合科技接受模式中的知覺娛樂性，探討其對手機遊戲消費行為之間的關係。本研究將遊玩動機區分成「成就型動機」、「社交型動機」以及「沉浸型動機」；遊戲特質偏好則以「奇幻性偏好」、「合理性偏好」、「神祕性偏好」和「控制性偏好」四大構面分析。至於玩家的消費行為，本研究將其分為「付費意願」、「付費金額」和「上癮度」。 本研究以發放網路問卷的方式進行，總共獲得有效問卷共1043份。經過統計迴歸分析後發現，三種遊玩動機均對付費意願有顯著正向影響，而遊戲特質偏好雖然同樣對付費意願與顯著關係，但在付費金額方面則呈現不相關，唯有「奇幻性偏好」高的玩家有高消費的傾向。「奇幻性偏好」、「合理性偏好」以及「神秘性偏好」都對遊戲的上癮度有顯著影響。其他顯著影響的因素將待於研究中一一解釋。 / The mobile game industry has been developing rapidly in recent years. Its high growing potential can be observed both in global and Taiwan markets. Some marketing studies even claim that mobile games would become the most profitable genre among the gaming market in the near future. The amount of research related to mobile games marketing increases in a fast pace, only reflecting this booming trend However, most of the studies by far merely focus on the content of games. Little academic research has been conducted on the players’ attitude toward games. Therefore, this study aims to bridge the gap between mobile gamers’ psychological status and their purchasing behaviors, offering a possible explanation for the reasons behind their purchases. This study used players’ motivation and preference on game characteristics as the independent variables, in which players’ motivation was classified into “achievement,” “social,” and “immersion,” while preference on game characteristics was divided into four categories: “fantasy,” “rationality,” “mystery,” and “control.” As for gamers’ behavior, it was analyzed in terms of three dimensions: “purchasing intention,” “spending,” and “addiction.” After the regression analysis, the results show that all of the above-mentioned motivation constructs exhibit significant association with purchasing intention. Players with high preference on fantasy theme have greater tendency to spend more on mobile games. Furthermore, preferences on fantasy, rationality, and mystery, have positive relationships with game addiction.
