Knowledge is key to firm growth. Managers perform knowledge-based managerial roles that foster firm growth. Surprisingly, little attention has been paid to examine the role of knowledge-based managerial roles in business model innovation (BMI). To fill this gap, the purpose of this study is to examine the impact of knowledge-based managerial roles (interpersonal, informational and decisional) in facilitating BMI within the context of family-owned businesses (FOBs) in Pakistan. This research employed a quantitative research design with a deductive-research approach, and the survey method is used to collect data from FOBs of Pakistan. Data collected were analysed through SPSS 23.0 and Smart PLS 3.0. Structural equation modeling (SEM) is used to test the different relationships proposed between selected variables. Results of study exhibit that knowledge-based managerial roles (IPR, IFR and DCR) have positive and significant associations with both BMI and knowledge-creation process. Further, the knowledge-creation process acts as a partial significant mediator between all three types of Mintzberg managerial roles and BMI. The study presents a novel contribution for government and policymakers to realize the importance of FOBs and create opportunities for their survival and growth that will boost up the economic growth of the country.

知识是企业成长的关键。管理人员执行以知识为基础的管理角色，以促进公司成长。令人惊讶的是，很少有人关注以知识为基础的管理角色在商业模式创新（BMI）中的作用。为了填补这一空白，本研究的目的是研究基于知识的管理角色（人际、信息和决策）在促进巴基斯坦家族企业（FOB）背景下的 BMI 方面的影响。本研究采用定量研究设计和演绎研究方法，采用调查方法从巴基斯坦FOBs收集数据。收集的数据通过 SPSS 23.0 和 Smart PLS 3.0 进行分析。结构方程模型 (SEM) 用于测试所选变量之间提出的不同关系。研究结果表明，基于知识的管理角色（IPR、IFR 和 DCR）与 BMI 和知识创造过程具有积极且显着的关联。此外，知识创造过程在所有三种类型的 Mintzberg 管理角色和 BMI 之间起到了部分重要的中介作用。该研究为政府和政策制定者提供了一项新的贡献，让他们认识到 FOB 的重要性，并为他们的生存和发展创造机会，从而促进该国的经济增长。
