A method for analyzing injection molding conditions, which takes into consideration the compressibility of molten resin in a barrel and mechanical delays in resin flow caused by constituent elements of an injection molding machine and analysis results thereof are provided. In a method for analyzing injection molding conditions in which, by using input data having shape data () and injection conditions data () to perform flow analysis of the process of filling the inside of the mold with molten resin, analysis of the pressure maintenance process from the filling with molten resin to the gate sealing, and analysis of the cooling process within the mold after gate sealing, the pressure and temperature distributions of resin within the mold are calculated, data () regarding compressibility of molten resin held in the barrel of the cylinder and mechanical data caused by constituent elements of the injection molding machine are added to the input data.
