The purpose of the present invention is to obtain a method for evaluating the motility of a polymer composition in a high-temperature region of 150°C or higher. A method for evaluating physical properties of a polymer composition, including a step for obtaining a sample thin film including a fluorescent probe comprising a fluorescent rare earth metal complex formed on a substrate and having a melting point of 200°C or higher, and a target polymer composition, and a step for obtaining a correlation between a fluorescence characteristic and the temperature of the sample thin film.
