The fourth industrial revolution challenges the existing understanding of innovation and upgrading in the global economy. It blurs traditional sectoral boundaries based on distinctive products and technologies and calls into question a traditional global value chain (GVC) perspective, which, similar to the sectoral systems of innovation approach, examines innovation and upgrading from a sector-based orientation. Building upon the recent reformulation and extension of GVC governance theory, this article proposes the notion of cross-sectoral GVC governance to capture the new stage of platform-based industrial development. It specifies the conceptual dimensions of cross-sectoral GVC governance in terms of the mode of governance (i.e., driving, linking, and normalizing), the overall GVC structure in terms of polarity, and firm strategies of managing GVCs. The proposed framework is illustrated using the case of smartphones as a platform product, focusing on four lead firms—Samsung, Apple, Huawei, and Google—to showcase divergent firm strategies for governing cross-sectoral linkages related to innovation and upgrading.

跨部门全球价值链的创新、升级和治理：以智能手机为例

第四次工业革命挑战了对全球经济创新升级的现有认识。它模糊了基于独特产品和技术的传统部门界限，并质疑传统的全球价值链 (GVC) 视角，该视角类似于部门创新方法系统，从基于部门的方向审视创新和升级。基于最近对全球价值链治理理论的重新构建和扩展，本文提出了跨部门全球价值链治理的概念，以捕捉基于平台的产业发展的新阶段。它从治理模式（即驱动、联动和常态化）、极性的整体全球价值链结构、和管理全球价值链的坚定战略。提议的框架以智能手机作为平台产品为例，重点关注三星、苹果、华为和谷歌这四家领先公司，以展示不同的公司战略，以管理与创新和升级相关的跨部门联系。
