Multidivisional Structure and Productivity: The Contingency of Diversification Strategy
基于62家企业的纵向数据，发现多部门结构对生产率的影响取决于多元化战略：垂直整合企业效率下降，相关多元化企业效率上升，非相关多元化企业生产率提升不显著。
This study examines the relationship between multidivisional (M‐form) structure and productivity. The relationship is hypothesized to vary with diversification strategy. Findings based on longitudinal analysis of productivity data from 62 firms in industries, indicate that following M‐form implementation, productive efficiency decreases for vertically integrated firms and increases for related diversified firms. For unrelated diversifiers the moderate increase in productivity is not significant.
