The invention discloses a high-dimensional variable sampling number-oriented product quality monitoring method. S2, defining parameters of the product quality monitoring method oriented to the high-dimensional variable sampling number; S3, determining a false alarm rate in a controllable state of a monitoring process; S4, constructing a process monitoring statistic oriented to the high-dimensional variable sampling number; S5, determining a process stop rule based on an error discovery rate; in the quality management link of the production and manufacturing process, the characteristic number of inspection products is higher and higher, and the inspection batch size (namely the sampling number) can be different due to the problems of sample or data missing and the like, the product quality is monitored in real time through the high-dimensional variable sampling number-oriented product quality monitoring method; therefore, the product quality monitoring efficiency is improved. 本发明公开了一种面向高维可变抽样数的产品质量监测方法，步骤S1:确定
