High-quality development relies on efficient governance, and government-enterprise cooperation has become a common practice in the field of digital governance. However, the “ government + state-owned en- terprise” digital governance model faces practical difficulties, such as difficulty in coordinating benefit goals, determining responsibility boundaries, and ensuring governance effectiveness. Against this backdrop, the prin- ciples of co-construction, joint governance, and shared benefits should serve as the fundamental guidelines for optimizing the “ government + state-owned enterprise” digital governance model. Specifically, the optimization paths can be designed around four key aspects: (1) clarifying the boundaries between the “ government + state- owned enterprise” and “ government + private enterprise” digital governance models; (2) streamlining the insti- tutional norms for state-owned enterprises’ participation in government digital governance; ( 3) building plat- forms to facilitate state-owned enterprises’ involvement in government digital governance; and ( 4) strengthe- ning the sustainable driving force for state-owned enterprises’ participation in government digital governance. These measures are expected to further promote China’ s digital governance to a new level and accelerate the modernization of the governance system and governance capacity.
