Measuring Typhoon Disaster Service Benefits of Meteorological Satellites: Taking FY-3A as an Example

Measuring the comprehensive benefits of meteorological satellite observation systems in typhoon monitoring, early warning and disaster prevention and mitigation has become a key basis for formulating the development plan and strategic layout of the new generation of meteorological satellites. This paper takes FY-3A as an example and combines the PSM-DID model with the input-output model to measure the comprehensive benefits generated by meteorological satellite services in reducing the losses caused by typhoon disasters. Research findings: (1) Significant direct benefits: meteorological satellite services have reduced the direct economic losses of a single typhoon event in the coastal areas of the mainland by 1.78%, equivalent to an economic benefit of 535.4 million yuan. (2) The indirect benefits vary greatly among different industries: construction industry, transportation and warehousing industry, agriculture, forestry, animal husbandry and fishery industry, metal smelting and rolling processing industry, etc. have the highest indirect benefits generated by meteorological satellite services, the indirect benefit value generated by meteorological services during typhoons amounts to as much as 1.6154 billion yuan. (3) Screen out the top ten highly sensitive industries affected by meteorological satellite services, namely construction industry, transportation and warehousing industry, agriculture, forestry, animal husbandry and fishery industry, metal smelting and rolling processing industry, etc. Finally, policy suggestions are put forward. The research method of this paper can provide reference for the comprehensive benefit measurement of other meteorological satellites, and the research results can provide reference for the government and meteorological departments.
