PROBLEM TO BE SOLVED: To enhance reliability by performing analysis or the like using injection molding CAE with high precision and to stably perform the setting or control of a fine part in an injection process with high precision. SOLUTION: When the resin characteristics of a molten resin R in the injection molding machine M are measured, an injection nozzle 2 is set to a closed state while the molten resin R is set to a filled state in front of the screw 4 in a heating cylinder 3 and the screw position S and the resin temperature T, both of which correspond to a change in pressure P, are detected by successively changing the pressure P with respect to the molten resin R from the screw 4. The change characteristics of the compression ratio C (P, T) of the molten resin R with respect to the change in pressure P are calculated from the screw position S and the resin temperature T to the detected arbitrary pressure P.
