This paper focuses on the compiling and the role of the socially responsible index. Socially responsible investment originated from ethically investing teachings and developed on growing social awareness. Social responsibility indexes are products of the development of social responsibility investment. The Domini 400 Social Index, the Dow Jones Sustainability Indexes and the Calvert Social Index are typical cases of international social responsibility indexes. They are compiled on the base of consistency, flexibility and transparency and their component stocks are selected according to triple bottom line. Compared with international experiences, China’s social responsibility indexes have a shorter history and some problems.
