The multi-indicator synthetical assessment method (composite indicator) is one of the two basic methods used by economic statistics to solve the "additivity issue" (the other being the value indicator), especially when facing the trend of "measured welfare turn." Its importance is highlighted, and it is an indicator tool that cannot be underestimated in the empirical analysis process. In the development process of composite indicators, it is particularly important to pay attention to the entanglement and clarification of "reason" and "mathematics." We should not only prefer the "technical approach" and focus on improving the mathematical difficulty of the method but also pay attention to the "mechanism approach" of the method. We should also pay attention to the "consistency" of different composite methods in methodology, that is, to improve, expand, deepen, and promote the methodology of composite indicators from a systematic "visual field."
