New digital technologies have prompted many firms, including family firms, to innovate their business models. We study the role of dynamic capabilities as mediator in the relationship between family influence and digital business model innovation (BMI), and the moderating role of environmental dynamism. Based on unique survey data from 1,444 German firms with and without family influence, we reveal that knowledge exploitation, risk management, and marketing capabilities mediate the positive relationship between family influence and digital BMI. Surprisingly, and contrary to our assumption, we find that the positive relationship between family influence and dynamic capabilities is weakened rather than strengthened by environmental dynamism. Our findings hold important implications for family business innovation and digital BMI research, offering valuable insights into the role of dynamic capabilities and environmental dynamism in the digital economy.

新的数字技术已促使包括家族企业在内的许多公司创新其商业模式。我们研究了动态能力在家庭影响力与数字业务模型创新（BMI）之间的关系中作为中介的作用，以及环境活力的调节作用。根据来自1,444家有或没有家族影响力的德国公司的独特调查数据，我们发现，知识开发，风险管理和营销能力可调节家族影响力与数字BMI之间的积极关系。出乎意料的是，与我们的假设相反，我们发现家庭影响力与动态能力之间的积极关系被环境动力削弱而不是加强。我们的发现对家族企业创新和数字BMI研究具有重要意义，
