As ports seek to maintain support for their operations amidst growing environmental awareness and social pressure, it is important they provide benefits for the local population to offset negative impacts. Ports can add additional economic benefits for the cities they are located in by encouraging maritime clusters, industrial development, a circular economy, and waterfront development. The current level of adoption, interest in future adoption, barriers to implementation, and attitudes towards the views of the local population were assessed via an online questionnaire sent to port authorities in 26 countries. The potential and willingness of ports to be on the frontline of the transition to a circular economy globally has been clearly identified for the first time, seeing a 60% increase between current levels of adoption and future interest in adoption. Barriers to a circular economy are comparable to barriers to widely adopted methods, such as industrial development and a waterfront economy. It is likely that circular economy activities in port cities will add additional local benefits and reduce the negative impacts of a port. A new framework is proposed to help ports and cities collaborate and encourage greater adoption of the circular economy.

良性循环？通过采用循环经济原则增加港口的本地利益

随着港口在环境意识和社会压力不断增强的情况下寻求维持对其运营的支持，重要的是它们为当地居民提供利益以抵消负面影响。港口可以通过鼓励海洋集群、工业发展、循环经济和滨水发展，为其所在城市增加额外的经济效益。通过发送给 26 个国家/地区的港口当局的在线调查问卷，评估了当前的采用水平、未来采用的兴趣、实施障碍以及对当地居民意见的态度。首次明确港口处于全球循环经济转型前沿的潜力和意愿，当前的采用水平与未来的采用兴趣之间增加了 60%。循环经济的障碍与广泛采用的方法（例如工业发展和滨水经济）的障碍相当。港口城市的循环经济活动很可能会增加当地的额外利益并减少港口的负面影响。提出了一个新框架，以帮助港口和城市合作并鼓励更多地采用循环经济。
