Abstract: Research on the impact of second-generation characteristics on family business innovation is limited by several factors. First, existing studies often focus on the interaction effects of a single or a few second-generation characteristic variables due to methodological constraints, lacking a systematic and comprehensive analysis of multidimensional second-generation variables. Second, most research employs an explanatory perspective to infer causal relationships, while giving limited attention to systematic quantitative analyses from a predictive perspective. This study, adopting a predictive approach and employing machine learning methods, uses data from 2,369 publicly listed Chinese family firms to comprehensively examine the predictive impact of multidimensional second-generation characteristics on family business innovation. It further identifies the key second-generation characteristic factors that significantly influence the prediction of family business innovation levels and elucidates their predictive mechanisms. The findings indicate that: (1) among personal characteristics, the duration of second-generation involvement is a strong predictor of R&D investment, while second-generation age is a stronger predictor of R&D output; (2) in terms of succession methods, the second-generation’s shareholding ratio is a strong predictor of family business innovation levels; (3) the relationships between the second-generation shareholding ratio, age, involvement duration, and family business innovation levels exhibit non-linear characteristics. The conclusions of this study provide valuable insights for family businesses during the intergenerational succession period on how to enhance innovation capabilities through the role of the “successor”.
