This paper uses the members of Taiwan Not-for-profit (NPO) Self-Regulation Alliance as samples, to estimate the responsiveness of information transparency, revenue characteristics, and expense characteristics to donations. The results indicate that information transparency, revenue and expense characteristics exist significantly association with donations. In specific variables, the results show that internet information disclosure levels (IDL), grant revenue, and personnel expense have significant positive association with donations, while service price has significant negative association with donations. Hence NPOs with higher IDL, grant revenue, and personnel expense, or lower service price, will get more trust and donations from donators.
