IS HIGH EMPLOYEE TURNOVER REALLY HARMFUL? AN EMPIRICAL TEST USING COMPANY RECORDS.
研究员工流动率与企业绩效的倒U型关系，基于110家临时就业机构办公室的数据，发现高流动率有害，但倒U型关系未得到确切证实。
We tested the hypothesis that employee turnover and firm performance have an inverted U-shaped relationship: overly high or low turnover is harmful. Our analysis was based on economic performance data from 110 offices of a temporary employment agency. These offices had high variation in turnover but were otherwise similar, allowing control for important intervening variables. Regression analysis revealed a curvilinear relationship; high turnover was harmful, but the inverted U-shape was not observed with certainty.
