Is state-owned enterprise merging private enterprise “market choice” or “space crowding” ? —Based on the motives of equity transfer of mixed-ownership enterprises

Many state-owned enterprises have mergers and acquisitions (M&A) with private enterprises, which has caused private enterprises to worry about their living space being squeezed. Based on 572 data records about equity transfers of Chinese listed companies extracted from CSMAR4.0 from 2013 to 2020, this paper categorized ownership structures into three categories: privatization of state-owned enterprises (Category 1), state-owned enterprises merging private enterprises (Category 2), and state-owned enterprises merging state-owned enterprises (Category 3). The categorical regression of ex-ante equity transfer motivation revealed that the motives for Category 1 conformed to the phenomenon of the “pretty girl gets married first” and “embezzlement view.” Category In contrast, the motives for Category 2 conformed to the “fiscal revenue view.” The categorical regression of ex-post equity transfer motivation showed that all three types significantly improved various efficiencies and represented an optimal allocation of resources. Moreover, it was revealed that the transfer of equity to state-owned enterprises by inefficient private firms in Category 2 also significantly improved enterprise efficiency. Thus, it can be considered as a rational behavior of market selection and never squeezed the space crowding. Further analysis showed that the efficiency improvement is due to the symbiotic development relationship rather than the antagonistic relationship between heterogeneous shareholders. Therefore, it is suggested to initiate market-oriented reform by actively developing ownership mixed-ownership economy and adhering to the “two unwavering” basic economic system.
