Abstract: Constructing open digital platforms has become a key pathway for industrial enterprises to achieve digital transformation and ecological synergy. However, there is still a lack of systematic research on how to integrate external innovation capabilities and internal business systems through platform openness. This study reveals the construction path and ecological synergy mechanism of open digital platform capabilities through a longitudinal case analysis of five industrial enterprises that were pioneers in building open digital platforms. The findings indicate that: (1) The construction of open digital platform capabilities follows a three-stage evolutionary path of “open infrastructure—ecological synergy expansion—value co-creation iteration,” characterized by the progressive features of “connection—symbiosis—evolution.” (2) The “digital-ecological” capabilities, through three major strategies of “introduction—collaboration—governance,” have achieved ecological synergy in “technical interfaces—resource networks—rule systems,” promoting the transformation of the platform from a tool-based infrastructure to an innovation ecosystem hub. The research results reveal the dynamic laws of open digital platform capability construction, expand the intersection of open digital platform theory and ecosystem research, and provide practical insights for industrial enterprises to accelerate ecological transformation through open strategies.

摘要： 构建开放式数字平台已成为工业企业实现数字化转型与生态化协同的关键路径，但如何通过平台开放性整合外部创新能力与内部业务系统仍缺乏系统研究。通过对5家率先构建开放式数字平台的工业企业进行纵贯式案例分析，揭示了开放式数字平台能力的构建路径与生态协同机制。研究发现：（1）开放式数字平台能力遵循“开放基础建设—生态协同扩展—价值共创迭代”三阶段演化路径，具有“连接—共生—进化”的进阶特征；（2）“数字—生态”能力通过“引入—协作—治理”三大策略，实现了“技术接口—资源网络—规则体系”的生态化协同，推动平台从工具性基础设施向创新生态中枢转型。研究结果揭示了开放式数字平台能力构建的动态规律，拓展了开放式数字平台理论与生态系统研究的交叉领域，为工业企业通过开放战略加速生态化转型提供了实践启示。
