Traditional control and single-business digital solutions cannot adapt to large-scale operations, and existing research lacks a universal full-life-cycle closed-loop model. Based on the theories of full-life-cycle management, closed-loop data governance and system dynamics, this paper selects panel data of 127 mixed-business stores from 2021 to 2025 (Huber M &amp; Fisher L., 2022), and conducts empirical research by adopting the entropy weight TOPSIS method, system dynamics simulation and mediating effect model. The study finds that data governance, intelligent decision-making, process closed-loop management and dynamic iteration can significantly improve store control efficiency; business adaptation exerts partial mediating effect, and the sensitivity of control parameters varies across different business formats. On this basis, this paper constructs a layered and adaptive implementation path, and verifies the feasibility of the model combined with enterprise cases. The research can fill the theoretical gap of digital control for multi-business stores, and provide theoretical support and replicable practical schemes for differentiated collaborative governance of chain enterprises.</p> Zeng Jingye Copyright (c) 2026 Insights in Social Science 2026-08-31 2026-08-31 4 3 1 11 10.53104/insights.soc.sci.2026.09001
