The invention discloses a GS screening system-based animal cell high efficiency expression vector and an application thereof. The invention also provides a method for constructing the expression vector. The method comprises the following steps: replacing a CMV promoter expressed by target gene driven by a starting vector pIRSE-EGFP-B by an hCMV promoter, and inserting labeled gene into the starting vector pIRSE-EGFP-B to obtain the expression vector. Experiments in the invention prove that the vector pIRSE-EGFP-B is obtained through mutation of the BamHI site of a pIRSE-EGFP vector, the original CMV promoter is replaced by the human hCMV promoter, and the GS labeled gene is inserted in order to obtain the high efficiency expression vector. The high efficiency expression vector has advantages in target protein expression, and a high efficiency expression cell line can be rapidly obtained through the above GS system.
