“一带一路”债务可持续的软法路径

债务可持续是推动\"一带一路\"高质量发展的关键议题之一,其实质是保障\"一带一路\"借款国融资需求和还款能力间的平衡。2017年起渲染至今的\"债务陷阱\"问题,与新冠肺炎疫情期间达成的一系列G20公共债务倡议,都说明这个议题的现实重要性。国际社会应对公共债务可持续问题的传统思路是软法规制,包括联合国贸易和发展会议(UNCTAD)制定的《负责任的主权借贷原则》、世界银行和国际货币基金组织(IMF)共同制定的《债务可持续框架》及巴黎俱乐部制定的债务重组基本原则,中国倡议的《\"一带一路\"债务可持续分析框架》是这一领域的最新成果。软法路径符合国际社会规制公共债务的传统,也是中国致力于\"一带一路\"债务可持续的可行选择。建议推动《\"一带一路\"债务可持续分析框架》多边化,推广亚洲基础设施投资银行分析债务的做法,适时启动加入巴黎俱乐部谈判工作,建立应对债务危机的全球援助机制,创造政府和社会资本合作(PPP)最佳国际实践。

Non-farm work and food security among farm households in Northern Ghana

This paper examines the impact of non-farm work on household income and food security among farm households in the Northern Region of Ghana. We analyze the impact by employing propensity score matching method that accounts for self-selection bias. The matching results show that participation in non-farm work exerts a positive and statistically significant effect on household income and food security status, supporting the widely held view that income from non-farm work is crucial to food security and poverty alleviation in rural areas of developing countries.

Assessing emerging technologies—Methodological challenges and the case of nanotechnologies

Technology Assessment reflecting on R&D and technological trends in the area of nanotechnology and its implications is confronted with the problem that most scientific endeavours of nanotechnology can be allocated to basic research while most of the technological visions related to nanotechnology are far (> 10 years) in the future. Since technology assessment has to integrate the socio-economic context of a technical product in order to be comprehensive, in the case of nanotechnology a preparing step is necessary which connects the ongoing basic research with the visions communicated either by the scientist themselves or by the media. In this paper we propose to adapt the well known tool ‘roadmapping’ to contribute to the solution of this problem. This poses new challenges for roadmapping methodology in terms of level of aggregation and timeframe.
