Research on the configuration path of drought impact on grain production:Qualitative comparative analysis based on fuzzy sets
Based on the perspective of configuration,this paper took 31 provinces(autonomous regions and municipalities)in China as research objects,and chose 1990,1995,2000,2005,2010,2015 and 2020 as typical cases to explore the configuration path of drought and various factors affecting food production.The results showed that,food production was affected by many factors,and drought could not independently affect food production.There were four path configurations in high grain production,which were resource input type,government support type,government support + resource input type and government support + technology input type.There were six path configurations in low grain production,which could be summarized into three types,such as reduction due to drought + absence of government + lack of resources,reduction due to drought + lack of resources,reduction due to drought + lack of resources + lack of technology.The influencing factors of grain production were not only asymmetrical,but also had significant tempo-ral and spatial differences.
