Progress towards the research on the doughnut-shaped framework as a novel roadmap for sustainable development assessment
Sustainable development is a hot topic of universal concern and heated discussion among all humanity.As an extension of the planetary boundaries framework to the socio-economic field,the doughnut-shaped framework provides new ideas for sustainable development assessment across the globe.This paper provides a systematic review and in-depth analysis of the concept,theoretical basis,localization expansion,existing problems,and improvement directions of the doughnut-shaped framework.The research has shown that the doughnut-shaped framework organically integrates environmental boundaries and basic socio-economic needs,thereby incorporating environmental sustainability and socio-economic development into the same analytical framework.This framework is based on the theory of steady-state economy,emphasizing the need for both a certain amount of man-made capital to meet human's socio-economic needs and a constant amount of natural capital to maintain environmental sustainability.The localization expansion applications of the doughnut-shaped framework mainly focus on the evaluations of environmental sustainability and socio-economic development respectively,lacking in-depth explanation of internal interaction mechanisms.In order to enhance the scientific understanding of the transmission mechanisms between environmental boundaries and socio-economic boundaries,it is urgent to strengthen research on the interactions between environmental boundaries,ecosystem services,and socio-economic boundaries based on ecosystem units.The guiding value of the doughnut-shaped framework for global and regional sustainable development needs to be further enhanced.Due to its high compatibility with China's development philosophy of balancing ecological protection red line and socio-economic bottom line,the doughnut-shaped framework has great potential for application in the field of sustainable development in China.
