Problems solved by technology

[0003] However, as the social influence of tax credit continues to increase in the construction of the corporate tax credit system, there are still some problems in the management of tax credit. For example, the coverage of tax credit management is still relatively narrow, and the evaluation update cycle is still long. The evaluation indicators are relatively simple. Lack of credit repair mechanism, credit linkage needs to be strengthened, etc.

Embodiment Construction

[0031] Some concepts that may be involved in this application, such as blockchain: in essence, it is a shared database in which the data or information is transparency”, “collective maintenance” and other features.

[0032] Bayesian Networks: are a class of graphical models that use probability theory to deal with uncertainty arising from the correlation of conditions describing different knowledge components.

[0033] Classification: Use the classified and known data set to build a classification model, and use the obtained classification model to give the category to which the unclassified data belongs.

[0034] PCA: Principal Component Analysis (Principal Component Analysis), as an effective multivariate statistical method, is often used in feature extraction. It uses a small number of principal components to replace more original feature information, which greatly reduces the amount of calculation for subsequent classification.

[0035] Index: the smallest unit for assess...

Abstract

The invention discloses an enterprise credit evaluation system and method based on a block chain and tax data, and relates to the technical field of block chain application. Enterprise data are preprocessed, taxation data and other related data are classified; standardized processing is carried out on the classified tax data and other related data; different indexes for measuring enterprise creditare generated; indexes which greatly influence enterprise credit are obtained by utilizing public cloud through a PCA extraction method. Enterprise credit is calculated and evaluated through a Bayesian classification algorithm, a public cloud is utilized to deploy a block chain cluster, an enterprise data service node is set, enterprise data and an enterprise credit evaluation result are subjected to uplink operation, and enterprise credit evaluation sharing is achieved through a block chain consensus mechanism.

Description

technical field [0001] The invention discloses an enterprise credit evaluation system and method, and relates to the technical field of block chain application, in particular, an enterprise credit evaluation system and method based on block chain and tax data. Background technique [0002] Tax payment, that is, the implementation process of taxpayers in taxation, is to pay part of the collective or individual income to the state according to the provisions of various tax laws of the state and according to a certain ratio. [0003] However, as the social influence of tax credit continues to increase in the construction of the corporate tax credit system, there are still some problems in the management of tax credit. For example, the coverage of tax credit management is still relatively narrow, and the evaluation update cycle is still long. The evaluation indicators are relatively simple. There is a lack of credit repair mechanism, credit linkage needs to be strengthened, etc....
