It also discusses the points of convergence for social work intervention in the e-commerce consumption behavior of vulnerable children from a theoretical perspective, clarifying the necessity and feasibility of such intervention. Meanwhile, it proposes intervention strategies for social work in addressing the e-commerce consumption behavior of vulnerable children, including the principles for strategy formulation, specific goals, implementation paths and methods. Overall, this study provides theoretical support and practical guidance for social work in intervening in the e-commerce consumption issues of vulnerable children.展开更多
