Can common institutional ownership inhibit the formation of zombie firms? Evidence from China

The survival of zombie firms severely crowds out healthy corporate investment and employment growth, eventually undermining economic growth potential. Hence, how to properly address the problem of corporate zombification is an essential part of achieving high-quality economic development in China. In recent years, the phenomenon of common institutional ownership has become increasingly widespread in the capital markets and has a significant impact on the strategic decisions of companies. There are currently two views on the corporate governance role of common institutional ownership: the synergistic governance effect and the collusive fraud effect. Using data from Chinese-listed firms from 2009 to 2021, this paper finds that common institutional ownership can significantly inhibit the formation of zombie firms. The higher the degree of their linkage and the greater the shareholding, the more pronounced the synergistic effect. The findings remained valid after considering the endogeneity issue and conducting robustness tests. Furthermore, the mechanism test suggests that common institutional ownership inhibits the formation of zombie firms by improving internal control quality and reducing agency costs. This paper contributes to the study of how to inhibit the formation of zombie firms by identifying common institutional ownership from the perspective of external governance mechanisms. In addition, this paper enriches the research on the economic consequences of common institutional ownership. Finally, various practical implications for policymakers may be realised, which may help curb the trend of corporate zombification through equity-based instruments.
