The invention provides a method for rapidly analyzing eukaryotic protein genomic data, and belongs to the technical field of protein genomic data analysis methods. According to the method for rapidlyanalyzing eukaryotic protein genomic data, II-type credible peptide fragments are obtained by adoption of a prokaryote multi-group data arrangement method and a screening method; and three different genome replying methods for the aims of predicting new genes, variant spliceosomes and point mutation genes and correcting structures of annotated genes are designed. The method provided by the invention is suitable for any sequenced eukaryon, and through a variant spliceosome and point mutation gene prediction method, the coverage degree of authentication is improved; by adoption of different relatively strict false positive control strategies, the credibility of the authentication is improved; and through predicting and correcting original mass spectrometric data, final new genes, variant spliceosome and point mutation genes, annotated gene structure series are analyzed, so that rapid authentication and analysis of eukaryotic mass spectrometric data are really realized.
