In the present invention, by adding a certain amount of the PA10T homopolymer into the PA6T homopolymer, a melting point of the PA6T homopolymer can be significantly decreased to be below a decomposition temperature, and thereby a processability of the PA6T homopolymer is improved. The prepared semiaromatic polyamide resin has a decreased melting point, and may be processed normally. The polyamide molding composition consisting of the semiaromatic polyamide resin has a good processability, and has excellent surface properties.
