Abstract：Fengyun meteorological satellites are one of the most important space infrastructures in China.Scientifically and accurately evaluating the benefits achieved by Fengyun meteorological satellites is not only of great significance for enhancing China's meteorological satellite application and service ca-pabilities,but also provides an important basis for national investment decision-making in meteorological satellite projects.By analyzing the application of Fengyun meteorological satellites'data in meteorological disaster prevention and mitigation,climate application,ecological civilization construction,atmospheric environment monitoring and space weather monitoring,we establish an information value chain of Fengyun meteorological satellites in this paper.Along this value chain,the socio-economic benefits gen-erated by Fengyun meteorological satellites during the entire information transfer process is quantitatively evaluated.By constructing the socio-economic benefits evaluation index system and benefits evaluation model of Fengyun meteorological satellites,and using the expert survey method and the analytic hierarchy process,we evaluate the contribution rate of Fengyun meteorological satellites'data in different meteoro-logical application services.Combined with the socio-economic benefits of meteorological application serv-ices,it is calculated that the socio-economic benefits obtained by Fengyun meteorological satellites in 2019 was 31.344 billion yuan(CNY).Then,based on the average annual investment in the Fengyun meteorological satellite project in 2019 and in the past 10 years,it is preliminarily concluded that the in-put-output ratio of the Fengyun meteorological satellite project is about 1∶30-1∶41.
