This paper estimates the responsiveness of internet information disclosure levels (IDL) to a number of economic variables, including organization characteristics, revenue characteristics, and expense characteristics. The empirical results show that IDL can be explained by revenue characteristics and expense characteristics, rather than organization characteristics. In specific variables, we find that activity area and payment expense respectively have positive and negative significant association with IDL. Hence national NPOs and those with low personnel expense have more IDL than others. Industry, age, donation revenue, and office expense don't have significant association with IDL, but the directions are consistent with our expectations. We also find that size and service price have positive significant association with IDL.
