In fact, the disclosure of environmental information by most enterprises in China is still only voluntary, and the form of disclosure is so chaotic that it is easy to be influenced by other enterprises.\u0000\u0000\u0000\u0000This study aimed to determine whether a firm's EID is affected by peer firms and contribute to the existing literature on the influencing factors of EID.\u0000\u0000\u0000\u0000The purpose of this article is to obtain a conclusion that a company''s environmental disclosure is influenced by its peer companies and to suggest practical implications for environmental regulation.\u0000\u0000\u0000\u0000An analytical framework incorporating the herd behavior hypothesis, the legitimate theory, and the stakeholder theory is constructed, and fixed effect estimation, as well as a two-stage least square, is used to test the hypotheses.\u0000\u0000\u0000\u0000There is a peer effect on environmental information disclosure of high-polluting firms.

Second, there are “demonstration effects” involved in EID. In the practice of regulations on disclosure, the smaller firms need to be under stricter scrutiny and set as models of EID to improve the efficiency of supervision and regulation. Third, enterprises have a stronger peer effect on the disclosure of sensitive information.
