本文將探討在不同消費者類型所產生的無為慣性影響。我們發現，小氣鬼較奢侈鬼容易產生無為慣性(實驗一)。接下來，將以往最主要會影響無為慣性的因素﹕吸引力差距大小作為干擾變數，發現只有在吸引力差距大的情況下，小氣鬼與奢侈鬼所產生的無為慣性才會有顯著差異(實驗二)。此外，我們發現自我控制會中介不同消費者類型所產生的無為慣性，驗證了自我控制是本研究中的中介變數(實驗三)。最後，本研究提供了證據來證明消費者類型與產品種類(良性品 vs. 惡性品)對購買可能性的交互效果，我們發現產品種類的不同會使不同消費者類型對其無為慣性產生影響(實驗四)。本研究拓展了無為慣性的研究方向─人格特質的領域，並提供實證應用與未來建議。

In this research, the inaction inertia effect caused by different types of consumers is discussed. The experiment 1 concludes that tightwads easily show inaction inertia than spendthrifts. The experiment 2, takes the different condition of attraction, the major factor of inaction inertia, as the moderate variable. It concludes that inaction inertia of tightwads and spendthrifts is significant different only when the large dif-ference condition of attraction. Besides, self-control mediate inaction inertia of dif-ferent types of consumers, which verifies self-control being mediate variable of this research in experiment 3. Finally, this research provides evidences to prove the interac-tion of purchase intention between types of consumers and product types (vice vs. virtue). In experiment 4, inaction inertia is affected by different product types and consumer types. This research expends the research domain of inaction inertia, person-ality traits. Furthermore, the management implication and future works are also given.
