Tax credit score calculating method and device

Abstract

The invention discloses a tax credit score calculating method and device. The method comprises that tax credit behavior record data of an object to be evaluated is obtained; on the basis of a pre-established evaluation index system model and the tax credit behavior record data, scores of first type of evaluation indexes with time attenuation characteristic are calculated regularly or in real timeby utilizing a time attenuation algorithm according to an evaluation period, an attenuation period and a scoring rule, and scores of non first type of evaluation indexes are calculated regularly or inreal time according to the scoring rule; and via a cardinal number scoring method, the index score, index weight and dimension weight of the evaluation index are multiplied to obtain a product of each evaluation index, and the products of different evaluation indexes are added to obtain a tax credit score of the object to be evaluated. Thus, a tax credit evaluation result is more accurate and timely, and influence of the evaluation indexes on a credit evaluation result is reduced with time.

Problems solved by technology

[0004] However, using the method of directly deducting points from the evaluation indicators, the scoring method is simple, will lead to a high error rate in the evaluation results, and cannot truly reflect the actual credit status of the taxpayer

In this way, when the final score differs by 1 point, the assessed grade may differ by one grade. For example, between 89 points and 90 points, it is the difference between B grade and A grade; This will lead to the fact that th
