Basic period proportion formula = (B/A)*{(1+b)/(1+a)}.

Among them, the current amount in the base period is A, the partial current growth rate is a, the overall current amount is B, and the overall current growth rate is b. The base period proportion formula is the partial fund volume divided by the overall fund volume. Base period proportion, as the name suggests, is to find the proportion in the base period.

Notes on the base period weight test points:

The base period weight is a knowledge point that is often tested in the civil service examination data analysis module, and it is also a difficult knowledge point. The main difficulty lies in the tedious formulas and complex calculations, and the candidates' score points on this knowledge point are also relatively low.

The so-called "base period proportion" is just a name. If the material tells us information about "a certain period" and what we want is the proportion of "a certain period in the past", this kind of question is about the proportion of the base period. Just start with the period given in the materials and the period when the question was asked. After the question type is determined, it is time to find data to represent the formula.
