Abstract
In this paper, we employ board monitoring mechanisms and within-firm governance variables to investigate the operating performance of 340 mergers and acquisitions in China over the 2004–2011 period. Our results document a significant deterioration in post-acquisition operating performance of acquiring firms over 12–36 months. We find independent directors, managerial shareholding, ownership concentration have a positive and significant impact on operating performance of acquiring firms. However, the related party transactions exert a negative and significant effect on matched control adjusted ROA. Further analysis of our sub-sample indicates that privately owned enterprises are better monitors compared to the state owned enterprises.
