Analysis of the relations between circular economy and sustainable development goals

ABSTRACT

Since the United Nations approved the eight Millennium Development Goals in 2000 and, 15 years later, the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs), the highest political institutions in the world have not stopped worrying about achieving the sustainability of the planet. Also in 2015, the European Commission prepared the European Union Action Plan for the Circular Economy, seeking a transition towards a less linear economy, in which products, materials, and resources are kept in the system for as long as possible and in which the generation of waste is minimized.

Since then, the European Union has continued issuing reports and communications to accelerate this process in search of a circular economy, making continuous references to the fact that, through circular economy initiatives, the SDGs would be fulfilled. In this context, the objectives of this paper are 1) to determine, through exploratory factor analysis and correlation analysis, whether there is a statistically significant relationship between circular economy initiatives undertaken in the EU and compliance with the SDGs; 2) to check, through a cluster analysis, if there are homogeneous groups of countries worldwide in terms of compliance with the SDGs; and 3) using this same technique, to check whether the countries that make up the EU achieve similar results in terms of compliance with the SDGs.     

循环经济发展模式及其应用

本文简要论述发展循环经济在生产中进行减量化、再利用和资源化的内涵及循环经济发展模式。实施循环经济是节约资源、能源,保护和改善环境,实现社会经济可持续发展的一重要举措,是经济发展的变革和转型。并以包头工业企业为范例,建立可行性的循环经济发展模式。     

美日德中汽车再制造业的比较和借鉴

为保持我国经济的持续快速发展,建设两型社会,促进循环经济发展,我国正大力发展汽车再制造业。汽车再制造业的发展最先是从国外开始的,美日德3个汽车生产大国和消费大国在汽车再制造方面的发展经验对我国的汽车再制造业发展有很强的借鉴作用。通过从法律法规、回收渠道、运作3个方面进行了国内外比较,以期寻求适合我国汽车再制造业的发展模式,促进我国汽车再制造业蓬勃发展。

Circular business models: Babbling initial exploratory

This research aims to map Brazilian companies that have business models aligned with the concept of the circular economy. Data were collected for this study through use of a survey and additional research based on the survey results. Within these businesses’ models, an emphasis on the second use of materials as well as the marketing of the product as a service has been highlighted.     

Urban sharing in smart cities: the cases of Berlin and London

ABSTRACT

Addressing urban sustainability challenges requires changes in the way systems of provision and services are designed, organised and delivered. In this context, two promising phenomena have gained interest from the academia, the public sector and the media: “smart cities” and “urban sharing”. Smart cities rely on the extensive use of information and communications technology (ICT) to increase efficiencies in urban areas, while urban sharing builds on the collaborative use of idling resources enabled by ICT in densely populated cities. The concepts have many similar features and share common goals, yet cities with smart city agendas often fail to take a stance on urban sharing. Thus, its potentials are going largely unnoticed by local governments. This article addresses this issue by exploring cases of London and Berlin – two ICT-dense cities with clearly articulated smart city agendas and an abundance of sharing platforms. Drawing on urban governance literature, we develop a conceptual framework that specifies the roles that cities assume when governing urban sharing: city as regulator, city as provider, city as enabler and city as consumer. We find that both cities indirectly support urban sharing through smart agenda programmes, which aim to facilitate ICT-enabled technical innovation and emergence of start-ups. However, programmes, strategies, support schemes and regulations aimed directly at urban sharing initiatives are few. We also find that Berlin is sceptical towards urban sharing organisations, while London took more of a collaborative approach. Implications for policy-makers are discussed in the end.     

财政自主能力与碳经济绩效：产业结构升级的中介效应

本文基于1997-2016年中国省级动态面板数据,从产业结构升级视角实证分析了区域财政自主能力作用于碳经济绩效的影响机理。研究发现：产业结构升级在财政自主能力影响碳经济绩效中发挥了中介效应;在高分权地区,财政自主能力能够通过产业结构升级促进碳经济绩效的增长;在低分权地区,财政自主能力会抑制产业结构升级并对碳经济绩效产生不利影响。进一步研究发现,在非农产业占比与非国有企业占比较高的省（区、市）域,财政自主能力能够通过产业结构升级对碳经济绩效产生更强的促进作用。本研究结论能够对地方政府从自身财政自主能力推动产业结构升级,为实现区域经济增长和环境优化的协同发展的政策制定提供理论指导。
