A method for preparing dimethyl 1,4-cyclohexanedicarboxylate (DMCD) is provided. The method includes hydrogenating dimethyl terephthalate (DMT) under a condition of a pressure of 20 to 30 kg/cmto continuously prepare the DMCD, and thereby increasing the selectivity of the DMCD. A method for preparing 1,4-cyclohexanedimethanol (CHDM) is further provided.
