The study attempts to, first, analyze the differential participation of the credit-rotating association (CRA) in urban and rural areas in Taiwan; secondly, explore its relationship with personal characters, income, financial management styles, and interpersonal trust. Based on the Social Change Survey data collected by Academia Sinica in 2000, the study finds that female, the young- and middle-aged, high education, high income, preferable of various financial investments, city residence were more likely to participate in CRA. When holding other conditions constant, the most important factor to explain the participation of CRA is personal financial management style. The study further suggests that, unlike a “mutual-help” or “favor-exchange” behavior for CRA in traditional Chinese society, the decision-making of participating the CRA today is more like a financial management with no difference of that in buying stocks or mutual funds. In other words, it is more appropriate to describe the CRA as a financial management decision rather than a personal favor exchange system or interpersonal trust relation.
