Since the advent of Uber, various shared mobility (SM) services have been introduced to exploit the blind spot of existing regulations in South Korea; nevertheless, the only limited services have been available because of the opposition from local stakeholders and the government's heavy-handed regulation. In this study, we discuss the diffusion and acceptance of SM services in South Korea's mobility market and its prospects from the perspective of socio-technical transitions. We designed a feedback model based on socio-technical system perspective to clarify the causal relationship between information and communication technology innovation and regulation in South Korea's mobility market; further, we applied a system dynamics simulation technique for testing three policy scenarios. We find that the diffusion of SM services is likely to be hampered if the current regulation is maintained and that the regulation reform without special measures could cause taxi services to lose a competitive advantage against SM services. Research and development investment through subsidies from SM services in the taxi industry innovation could encourage competitiveness, which could coexist with SM services, thereby bringing about a social benefit to adopters.

自优步问世以来，各种共享出行（SM）服务被引入，以利用韩国现有法规的盲点；然而，由于当地利益相关者的反对和政府的严厉监管，唯一可用的服务有限。在这项研究中，我们从社会技术转型的角度讨论了 SM 服务在韩国移动市场中的传播和接受情况及其前景。我们设计了一个基于社会技术系统视角的反馈模型，以阐明韩国移动市场中信息和通信技术创新与监管之间的因果关系；此外，我们还应用了系统动力学模拟技术来测试三种政策情景。我们发现，如果维持目前的监管，SM 服务的扩散可能会受到阻碍，并且没有特别措施的监管改革可能会导致出租车服务失去对 SM 服务的竞争优势。出租车行业创新中SM服务补贴的研发投资可以鼓励竞争力，这可以与SM服务共存，从而为采用者带来社会效益。
