Based on the perspective of the new system theory,this paper selects the data of China’s listed enterprises’M&A in the EU from 2001 to 2018,and uses the Negative Binomial Regression model and SUEST model for grouping regression to study the influence of inter organizational imitation on the location choice of cross-border M&A of enterprises with different ownership structures.The results show that Chinese enterprises tend to imitate the choices of other domestic enterprises when they choose the location of cross-border M&A.Non-state-owned enterprises tend to imitate more than state-owned enterprises.At the same time,the similarity of enterprise ownership structure will also affect the choice of enterprise imitation reference group,and the influence degree is deeper in state-owned enterprises.
