摘要: 以2010—2019年中国沪深A股上市公司完成的连续并购交易事件为样本,实证研究了上市公司是否存在连续并购的同伴效应,并检验了内部控制质量对连续并购同伴效应的作用机制。研究结果表明:同伴公司连续并购的平均交易数量越多,上市公司发生连续并购的可能性越大,连续并购的频率也越高,即上市公司的连续并购行为受同伴效应的影响;内部控制质量既能促进上市公司的连续并购行为,又能降低连续并购中可能存在的非理性行为,在连续并购受同伴效应影响的关系中发挥部分中介作用,即内部控制质量对连续并购的同伴效应具有一定程度的抑制作用。运用Sobel-Goodman检验、倾向匹配得分法(PSM)等进行稳健性检验,发现结论依然成立。

Abstract: This paper takes the serial M&A transactions completed by Chinese companies listed on A-share market in Shanghai and Shenzhen from 2010 to 2019 as a sample to investigate the peer effect of serial M&A, and examines the mechanism of internal control quality on the peer effect of serial M&A. It is found in the study that the greater the average transaction number of serial M&A in peer companies, the greater the probability of serial M&A of listed companies, and the higher the frequency of serial M&A. That is, serial M&A of listed companies are affected by the peer effect. The quality of internal control can not only promote serial M&A of listed companies, but also reduce the irrational behaviors that may exist in serial M&A. It plays a part of the mediating role in the relationship of serial M&A affected by the peer effect. That is, the quality of internal control has a certain degree of restraint on the peer effect of serial M&A. This paper uses Sobel-Goodman test and propensity score matching method (PSM) to conduct robustness tests, and finds that the above conclusions are still valid.

Key words: serial merger and acquisition(M&A); peer effect; internal control
