Building on the use of digital technology in supply chain management, this paper integrates data governance service providers into the supply chain. Given the distinct nature of data governance services, the paper illustrated the learning effect curve and simulated their output function. Building on this, four different supply chain data governance models were proposed, namely, manufacturer single governance model, retailer single governance model, manufacturer and retailer independent governance model, and manufacturer and retailer collaborative governance model. Constructed the profit model for the supply chain within the relevant framework. By vertically comparing the optimal decisions and system performance across various models, the study concluded that the collaborative governance model maximizes supply chain profit and is more responsive to factors that enhance overall profitability.
