Non-family Managers and Innovation in Family Firms: A Meta-Analysis

Abstract

Non-family managers play a crucial role in fostering innovation within family firms, yet their impact remains debated due to inconsistent research findings and a lack of comprehensive synthesis. This study integrates this effect through a meta-analysis of 213 effect sizes from 101 studies. The results demonstrate a positive influence of non-family managers on firm innovation, with a stronger effect on inputs than on outputs. Furthermore, this study identifies key governance and managerial contingencies at the firm level. First-generation control weakens this relationship, while non-family TMTs strengthen it. The implications for theory and practice are discussed, with suggestions for future research.
