The purpose of this study is to examine the effect of CSR disclosure to firm’s value at the year of disclosure and one year after CSR disclosure. Firm’s value is measured by MVE and Tobin's Q. This research also used the type of industry and firm size as control variables. This research uses secondary data.This data obtained from annual reports in 2008 listed companies at the IDX. Based on proportional random sampling method, 100 firms are used. From all these samples, 59% that have published financial report March 31, 2010. Level of CSR disclosure from this sample is 53.71%. This study employed statistical multiple regression to test hypothesis. The results of this study indicate that firm’s value is influenced by CSR disclosure in the year (ρ-value 0.003 and 0.022) and one year after the disclosure (ρ-value 0.011 and ρ-value 0.015). This research also shows that only the type of industry influences firm’s value.The implication is that companies should be more concern to report their CSR activities because it can influences the firm’s value.
