Disclosed is a method for evaluating storage suitability of rare metals. The method comprises : a first step of generating a first evaluation value indicating the degree of a global supply risk for a first rare metal selected among rare metals, a second evaluation value indicating the degree of corresponding force vulnerability to the global supply risk, and a third evaluation value indicating economic importance; a second step of calculating a fourth evaluation value indicating the degree of the total risk for the first rare metal by geometrically averaging the first evaluation value and the second evaluation value; and a third step of calculating a fifth evaluation value indicating the degree of necessity for storage of the first rare metal by using the third evaluation value and the fourth evaluation value, comparing the fifth evaluation value with a preset threshold value, and evaluating storage suitability of the first rare metal.(AA) Start(BB) End(S110) Step of generating a first evaluation value indicating the degree of a global supply risk for a first rare metal selected among rare metals, a second evaluation value indicating the degree of corresponding force vulnerability to the global supply risk, and a third evaluation value indicating economic importance(S120) Step of calculating a fourth evaluation value indicating the degree of the total risk for the first rare metal by geometrically averaging the first evaluation value and the second evaluation value(S130) Step of calculating a fifth evaluation value indicating the degree of necessity for storage of the first rare metal by using the third evaluation value and the fourth evaluation value, comparing the fifth evaluation value with a preset threshold value, and evaluating storage suitability of the first rare metalCOPYRIGHT KIPO 2019
