数字经济时代，新创企业依附平台生态来编排内外资源并创造价值已经成为一种普遍现象。然而，关于如何更好地“借力”平台生态，突破平台依赖型企业资源弱势，实现平台商业模式创新，仍尚待深入探析。基于资源依赖理论，本文以依托平台生态创业的新创企业为调研对象，利用层级回归方法和Bootstrap方法来分析平台依赖型企业网络权力对平台商业模式创新的影响，并进一步探究了资源编排的中介效应，以及数字技术可供性的边界作用机制。研究结果表明：（1）知识权力和结构权力对平台商业模式创新均存在倒U型关系；（2）知识权力和结构权力对资源编排均存在倒U型关系；（3）资源编排在知识权力和结构权力与平台商业模式创新之间起到部分中介作用；（4）数字技术可供性分别正向调节知识权力和结构权力与平台商业模式创新之间的关系，且数字技术可供性分别正向调节知识权力和结构权力与资源编排之间的关系。本研究在一定程度上丰富了网络权力与商业模式创新的研究，并对平台依赖型企业的商业模式创新实践具有一定的指导意义。

In the digital economy, it is increasingly common for startups to rely on platform ecosystems to manage both internal and external resources, driving value creation. However, there is a gap in understanding how platform-dependent enterprises can better utilize these ecosystems to overcome resource limitations and innovate their platform business models. This paper, grounded in the resource dependence theory, focused on startups that depend on platform ecosystems. Using the hierarchical regression and bootstrap methods, it examined how these enterprises′ network power influences business model innovation. The study also explored the mediating role of resource orchestration and the moderating effect of digital technology affordances. The findings revealed several key insights: (1) both knowledge power and structural power exhibit an inverted U-shaped relationship with platform business model innovation; (2) both knowledge power and structural power show an inverted U-shaped relationship with resource orchestration; (3) resource orchestration partially mediates the relationship between both types of network power (knowledge and structural) and platform business model innovation; and (4) digital technology affordances positively moderate the relationship between network power (both knowledge and structural) and platform business model innovation, as well as the relationship between network power and resource orchestration. This study has contributed to the literature on network power and business model innovation, and it will offer both theoretical and practical insights for platform-dependent enterprises seeking to innovate their business models.
