The invention relates to a method for judging difference of influence of standing and vibrating on phthalic ester transfer volume of a paper cup, which belongs to the technical field of analysis and detection. The method comprises the steps of: determining the test index as the transfer volume of phthalic ester in a mouth touch part material of the paper cup; the test factor is the vibrating frequency, which is respectively 0r/min and 80r/min; selecting check test design to design a transfer test scheme; preparing a test sample according to the test scheme; detecting the transfer volume of phthalic ester in the mouth touch part material of the paper cup by pulse unsplit stream sampling and a GC-MS (Gas Chromatography-Mass Spectrometer); detecting detection data by non-parameter tests of two independent samples, wherein the detection method comprises Man-Whitey U detection, and Moses Extreme Reactions; and judging whether remarkable difference of influence of standing and vibrating on phthalic ester transfer v
