Sustainable business model innovation (SBMI) has recently drawn great interest among academia and in practice. However, notwithstanding the surge in related academic and non-academic literature, a validated measurement scale for SBMI is not yet available. This study attempts to fill the gap by proposing a scale for SBMI, using an initial sample of 20 respondents (for qualitative enquiry), followed by a quantitative validation (using two sample sets of 130 and 200 SMEs from Saudi Arabia). The findings provided a 10-item scale, conceptualized under three factors, namely: sustainable value proportion innovation, sustainable value creation and delivery innovation, and sustainable value capture innovation. The study provides important implications for SME owners and managers, by highlighting that SBMI will result in enhanced SME performance as well as a competitive advantage.

可持续商业模式创新 (SBMI) 最近引起了学术界和实践界的极大兴趣。然而，尽管相关学术和非学术文献大量涌现，但尚未获得经过验证的 SBMI 测量量表。本研究试图通过提出 SBMI 量表来填补空白，使用 20 名受访者的初始样本（用于定性调查），然后进行定量验证（使用来自沙特阿拉伯的 130 和 200 家中小企业的两个样本集）。调查结果提供了一个 10 项量表，概念化为三个因素，即：可持续价值比例创新、可持续价值创造和交付创新以及可持续价值获取创新。该研究为中小企业所有者和管理者提供了重要的启示，
