This paper analyzes and compares the impacts that various index harmonization and dimensionless methods have on the comprehensive appraisal results,then carries on measure to the relative effectiveness of the dimensionless method through building the index of compatibility degree.The result of positive analysis shows that,in linear comprehensive evaluation model,the subtraction harmonization method and the two kinds of dimensionless methods of the range method or Z-Score method are more effective than other standardized methods.Choosing the suitable index standardization method can effectively improve the accuracy of the results of comprehensive evaluation.
