This study is to explore the nature, types, causes, and consequence of corruption among public servants in contemporary Taiwan. The factors that contribute to the occurrence of corruption will also be examined. We reviewed literatures on corruption. A total of 295 public servants were interviewed. Among then, 147 were public servants who didn’t have the records of corruption, the other 148 were criminals of corruption. We intend to examine how the structure, control, and opportunity factors affect the causes of corruption. The study concludes that: “Defraud property by making use of public position”, “steal or embezzle public property”, and “bribery” are the most popular types of corruption in Taiwan. Sixty percents of the corruption considered themselves to be responsible for their criminal acts. Corruption among public servants has been influenced by six factors: sex, age, level of education, shame, determent of aw, and types of position. Criminals punishment doesn’t deter their criminal intents, although they are afraid of the opportunity of connecting a crime. To reduce corruption opportunity, we must strengthen hardening the target and procedural control to aim at position that is likely to give rise to abuse.
