基于最优区分理论与资源编排理论，构建平台企业与互补者协同关系影响平台创新绩效的理论模型，以466份平台企业中高层管理者问卷数据进行检验。研究表明：平台企业与互补者协同关系和平台创新绩效呈现倒U形关系；平台企业与互补者协同关系和资源整合呈现倒U形关系，资源整合与创新绩效正相关，资源整合在平台企业与互补者协同关系和平台创新绩效间起部分中介作用；组织敏捷性正向调节资源整合与平台创新绩效的关系；平台开放度强化组织敏捷性在资源整合与平台创新绩效的调节作用；且进一步揭示了不同发展阶段的平台企业在上述结果中的异质性，发现成熟期企业的平台开放度与组织敏捷性在资源整合与创新绩效中的联合调节作用不显著。

Based on Optimal Distinctiveness Theory and Resource Orchestration Theory, this study establishes a theoretical model linking platform enterprises-complementor synergy relationship to platform innovation performance, empirically tested with 466 questionnaires from platform firms’ mid-to-senior managers of platform enterprises. Results reveal an inverted U-shaped relationship between platform enterprises-complementor synergy relationship and both innovation performance and resource integration. Resource integration partially mediates the synergy relationship-performance link while positively affecting innovation performance. Organizational agility positively moderates the resource integration-innovation performance relationship, and platform openness strengthens this moderating effect. Furthermore, heterogeneity exists across development stages: the joint moderating effect of platform openness and organizational agility on the resource integration-innovation performance linkage is non-significant for mature-stage platform enterprises.
