Racial Diversity and Firm Performance
研究了管理层种族多样性如何通过竞争强度影响企业绩效（市场份额和股票回报），并发现环境丰裕性会调节这一中介效应。
The authors examine the mediating role of competitive intensity in the relationship between managerial racial diversity and firm performance (i.e., market share gain and average stock return). Racial diversity relates to firm performance via firms’ capacity to compete intensively (i.e., to introduce new competitive actions frequently). An analysis reveals that environmental munificence moderates competitive intensity’s mediating effect: Racially diverse management groups compete more intensively and perform better when they compete in munificent environments. The authors also find support for a moderated mediation model that simultaneously tests all components of their framework.
