The research shows that there exists the peer effect when companies make unrelated M&As decisions in the same industry. This paper also makes further examinations and finds that the M&As experience and scale of companies enhance the peer effect. Moreover, companies with more industry competitions have more obvious industry peer effect. This paper enriches the M&As decisions theory and has guiding significance in practice. %K M& %K As Decisions %K Unrelated M& %K As %K Peer Effect %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=80935
