Abstract: For a long time as to Marx's class analysis method there is a misunderstanding that it only pays attention to the macroscopic analysis and lack of micro analysis, emphasizes the class relations "struggle" and ignore the class relations "sameness", just a simple class analysis to the exclusion of stratum analysis. Plough Marx's classical text deeply, grasp the Marx's thought logic and understand Marx's ideological concerns, it is not difficult to find, in Marx's class analysis method system, macro and micro analysis is combined with each other, the analysis of "heterogeneity" and "homogeneous" analysis is interconnected, class analysis and stratum analysis is mutual mapping.Steping out of the misunderstanding and eliminating the prejudice, which is crucial to adhere to and develop Marx's class theory and class analysis method better in the new period to is essential.
