Collective turnover in enterprises has a profound impact on relevant organizations and employee groups. The current study examined 102 cases of collective turnover of typical enterprises in China, and the data were selected from the database of CNKI of four types of published papers and one type of news from the newspaper from 1978 to 2021. The study found that collective turnover was concentrated in the popular and sunrise industries of the era. Of them, collective turnover of the manufacturing industry and the IT industry were always the focus. The main causes for it were individual factors, internal factors of the enterprise and the interaction factors between them. The direct causes for it were also mainly internal factors, which became the "fuse" or "catalyst" for collective turnover. The study refi ned the infl uential factors of collective turnover in the enterprise, and set up the model of its mechanisms of action, as well as the model of the main reasons and direct causes for it. The study suggests that preventing collective turnover requires paying more attention to the internal management of the enterprise as a whole, resolving the issue requires avoiding the accumulation of major causes, and mitigating collective turnover also requires paying attention to the role of direct causes.
