聚焦复杂社会技术系统中的设计方法论与创新机制，探讨设计如何从单一产品造型转向跨尺度、多利益相关者的系统建构。研究以系统思维、服务逻辑与模块化方法为工具，关注要素间的动态关系、反馈环路与涌现行为，推动设计介入组织流程、公共服务与城乡空间的结构性优化。强调自上而下框架与自下而上实践的结合，探索可迭代、低干预的系统干预策略。通过模型构建与原型实验，形成具有韧性、可扩展与适应性的创新方案，助力社会技术系统的可持续演化。

Focusing on design methodologies and innovation mechanisms in complex socio-technical systems, this study explores how design can shift from single-product styling to cross-scale, multi-stakeholder system construction. The research uses systems thinking, service logic, and modular approaches as tools, paying attention to dynamic relationships, feedback loops, and emergent behaviors among elements, promoting design intervention in organizational processes, public services, and the structural optimization of urban and rural spaces. It emphasizes the combination of top-down frameworks and bottom-up practices, exploring iterative, low-intervention system intervention strategies. Through model building and prototype experiments, it develops resilient, scalable, and adaptable innovation solutions that contribute to the sustainable evolution of socio-technical systems.
