Progress and prospects of research on wetland concession system
[Objective]Concession system is a new path to realize scientific protection and rational development of wetland resource assets,and it is also a key practice of ecological civilization con-struction in the new era.Analyzing the research framework,characteristics,and development trends of wetland concession systems both domestically and internationally can provide scientific refer-ence for the pilot work of wetland concession system in China.It also holds significant theoretical and practical implications for the study of natural resource asset delegation and agency mecha-nisms.[Methods]This paper combines systematic review with bibliometric methods,utilizing CiteSpace software for co-occurrence visualization analysis,to summarize the characteristics of wetland concession system research,identify existing issues,and propose prospects for future re-search on wetland concession systems.[Results]The results show that:(1)Studies in China follow the line of object-relationship-mechanism,while international studies focus on concession-environ-mental-individual;(2)Studies in China have undergone three stages of change,with increasing poli-cy guidance orientation.The change of international studies is less distinct,with a stronger focus on problem analysis;(3)In terms of institutional arrangement and policy recommendations,both Chi-nese and international studies are based on the inductive method,but there are methodological dif-ferences in problem-oriented perspective;(4)The wetland concession system with Chinese charac-teristics includes a multi-level rights and responsibility system,multi-stakeholder collaborative par-ticipation system,multi-path value realization system,and multi-type managemental guarantee sys-tem,featuring systematicity and high efficiency.[Conclusion]In the context of exploring the pilot wetland concession system and the current situation that practice is leading theoretical research,this article proposed to conduct a problem-oriented research by combining the theories of property rights,sustainable development,and community promotion.Meanwhile,the pilot practice should pay more attention to the holisticness of policy,systematicity of supervision,scientific quality of competition,and participation of residents.
