Corporate social responsibility (CSR) is still legally opaque in Taiwan. The securities authorities, after amending of securities regulation in December 2008, have begun to encourage public companies to disclose CSR activities. This paper, by reviewing the development of CSR in international societies, proposes that to make CSR work in Taiwan, there are four stages to be accomplished. The first stage is to reach semi-mandatory disclosure of CSR without social auditing; the second stage is to complete semi-mandatory disclosure with social auditing; the third stage is to complete mandatory disclosure with social auditing; and the four stage is, in addition to reach mandatory disclosure with social auditing, to require the content of disclosed information that is subject to criminal liability and administrative fines of Securities Exchange Law. This paper believes that, by means of government guidance, the first and second stages can be achieved smoothly. As to reaching the third and fourth stages, we need a consensus in international societies, and to upgrade Taiwan's society and culture as well.
