Sustainable development governance paths of bike‑sharing towards circular economy: policy simulation based on the practical case of Shanghai. (English)

SHANGHAI (China); CHINA

Bike-sharing is a typical mode of low-carbon travel for residents in the new era, and it is of great significance to explore how to realize its sustainable development. Based on the challenge of bike-sharing development in China’s cities, this study innovatively proposed a governance framework for the sustainable development of bike-sharing towards circular economy and provided governance paths based on the 3R principle. Then, this study constructed a complex system dynamics model integrating three sub-modules, i.e., reduction of faulty vehicles, reuse of faulty vehicles and recycling of scrapped vehicles. Based on the practical case of Shanghai, the sustainable development paths of bike-sharing towards circular economy were simulated. The results showed that: ① The five strategies of user behavior governance, recycling participation behavior governance, total amount control of urban launching, recovery monitoring of faulty vehicles and extended producer responsibility all played significant roles in the sustainable development of bike-sharing. ② With regard to individual strategies, extended producer responsibility system and recovery monitoring of faulty vehicles were the two best governance measures for the government to deal with faulty and scrapped vehicles, and for the operators to reduce production and recovery costs, and then to improve the efficiency of resource utilization, followed by the measures of total amount control of urban launching. ③ As for the combination strategy, the comprehensive and integrated implementation of the five strategies was the optimal governance path to promote the sustainable development of bike-sharing in China. After the comprehensive implementation, the total number of discarded bicycles in Shanghai is likely to be reduced by 71.15% from 2021 to 2031, the production and recycling costs of operators by 73.77%, and the carbon emissions by 87 800 tons. Ultimately, the present study proposes the implementation of the extended producer responsibility system, the scientific and prudent implementation of the total amount control, the guidance, standardization and restriction of users’ sustainable usage behaviors, the improvement of users’ willingness to participate in recycling, and the strengthening of the recycling monitoring of faulty vehicles. It is hope that this article could provide decision-making reference for the top-level design of sustainable development of bike-sharing and give assistance to the realization of the three strategic objectives of ‘building a transportation power, achieving carbon peak and carbon neutrality ’. Moreover, this article offers a fresh perspective for the research on the sustainability of sharing economy products, and lays a significant foundation for the subsequent integration of circular economy and sharing economy.

共享单车作为新时代居民低碳出行的典型交通工具，探讨如何实现其全生命周期的可持续发展意义重大。立足于中国城市 共享单车发展挑战，文章创新性提出了面向循环经济的共享单车可持续发展治理框架以及基于3R原则的治理路径，构建了集故障车 辆减量化、故障车辆再利用和报废车辆资源化三个子模块为一体的复杂系统动力学模型。在此基础上，基于上海市实践案例，对循 环经济视角下共享单车可持续发展路径进行了多情景仿真模拟。研究发现：①用户使用行为治理、回收参与行为治理、城市投放总 量控制、故障车辆回收监控和生产者责任延伸制五种策略均对共享单车行业的可持续发展起到显著作用；②就单一策略而言，生产 者责任延伸制和故障车辆回收监控是政府治理故障和报废车辆、运营商降低生产和回收处置成本，进而提升行业资源利用效率的两 种最佳治理举措，城市投放总量控制次之；③就组合策略而言，五种策略的综合集成实施是促进中国共享单车可持续发展的最优治 理路径，全面实施后，2021—2031 年上海市报废单车总量将减少 71. 15%，运营商的生产和回收处置成本节约 73. 77%，碳排放减少 8. 78万t。基于上述研究结果，文章提出实施生产者责任延伸制度、“科学谨慎”执行城市投放总量控制、“引导+规范+约束”用户可持 续使用行为、提高用户回收参与意愿、加强故障车辆回收监控等政策建议。这项研究旨在为共享单车可持续发展的顶层设计提供决 策参考，为国家“交通强国建设、碳达峰与碳中和”三重战略目标的实现提供助力。此外，文章为共享经济产品的可持续发展研究开 辟了新的视角，为后续循环经济与共享经济的集成探究奠定了重要基础。 [ABSTRACT FROM AUTHOR]
