有鑑於電腦駭客行為在企業間造成鉅額的損失，因此我們非常需要了解個人為何想做駭客行為，尋找有效的方式防範以降低犯罪率。過去，在駭客行為的研究當中常以動機、嚇阻理論、道德強度以及社會學習觀點來討論這個問題的答案。然而，過去的研究都是單獨的引用這些觀點，並沒有一個較完整且經過實證的研究模式來解釋是什麼原因影響駭客的行為意圖。以激勵理論、嚇阻理論、道德強度以及社會學習理論為基礎，本研究將建構一個完整的研究模式來解釋駭客的行為意圖，並且實際驗證。而且，我們發現有一個應該重視的因素被過去相關研究所忽略，那就是該駭客行為之情節輕重。我們認為在情節輕重不一樣的駭客行為中，各個因素影響行為意圖的程度將會不一樣。
本研究於台灣區採集了473個有效樣本驗證此研究模式，其結果支持我們所作的推論，外在動機、內在動機、道德強度、懲罰的必然性、懲罰的嚴重性以及社會影響都是影響潛在駭客決定是否採取駭客行為的因素，而且，在兩個情節輕重不一樣的駭客行為之間比較，上述的各個因素對於駭客行為意圖的影響有顯著差異。
總而言之，本篇研究整合了過去幾個較常被拿來討論網路駭客行為的觀點，並且提出一個更為整合且清楚的研究模式來解釋「網路駭客行為意圖」，更證實了影響此行為意圖的不只上述各觀點，還關乎於該網路駭客行為的情節輕重程度為何。

Given that computer hacking cause huge loss among firms, it’s necessary to understand how individuals engage to commit it. Most of previous research on computer hacking, discuss the reasons by motivation, deterrence theory, moral intensity and social learning theory. However, those perspectives were adopted in researches independently. Thus, there is a need for research to combine these perspectives to create a completed, empirical model to explain the hacker’s intention. Based on motivation theory, moral intensity, deterrence theory, and social learning theory, an empirical study of the intention of computer hacking was conducted. Moreover, we found the key factor ignored in the past, severity level of computer hacking, which will change the way of other factors affecting the intention. Data collected from 473 individuals in Taiwan confirmed our hypotheses and tested against the research model. The results support the proposed model in predicting intention to commit computer hacking. This study demonstrated that intrinsic motivation, extrinsic motivation, moral intensity, punishment certainty, punishment severity, and social influence were key factors that resulted in intention of computer hacking. In addition, severity level of computer hacking was a strongly significant moderator in all factors to intention. Lastly, several implications of information security management and direction to reduce computer hacking rate for practices are discussed.
