Research On Integrity Evaluation Model Based On Incomplete Information Evolution Game

B2B e-commerce is the key part of the community ecosystem with "Internet +" as the carrier,and the issue of integrity is the key to the healthy development of the e-commerce industry.Evaluation and evolution issues of B2 B e-commerce enterprise integrity are deeply discussed based on the combination of fuzzy comprehensive evaluation method,analytic hierarchy process,principal-agent model and evolutionary game theory.Evaluation and evolution of B2 B e-commerce enterprise integrity are studied from the following three aspects:1.In order to solve the problem of the limitation of enterprise integrity evaluation of B2 B e-commerce,integrating the analytic hierarchy process with fuzzy comprehensive evaluation method,a corporate integrity evaluation model based on fuzzy analytic hierarchy process in B2 B e-commerce is proposed.2.In order to describe the uncertain factors in the environment and increase the adaptability of the model and the accuracy of the prediction,based on the combination of principal-agent model,the random disturbance term and the evolutionary game theory,a Wright-Fisher multi-strategy integrity evolution model base on random disturbance under the principal-agent model is proposed.3.In order to curb the dishonest transactions of enterprises because of selfishness,the accountability mechanism is introduced.This makes the integrity benefits of the whole B2 B e-commerce platform reach the best,and effectively suppresses the fraud between enterprises in B2 B e-commerce.At the same time,it provides a solution to the problem about the governance of integrity in B2 B e-commerce,which is conducive to the development of China's e-commerce integrity system.Due to the enterprise integrity evaluation model of B2 B e-commerce is not perfect enough,based on the combination of fuzzy comprehensive evaluation method and the analytic hierarchy process,a corporate integrity evaluation model based on fuzzy level in B2 B e-commerce is proposed.Then,further explore the future development direction of corporate integrity in B2 B e-commerce,considering the complexity of the ecological community and the influence of uncertain factors in the environment,a Wright-Fisher multi-strategy integrity evolution model base on random disturbance under the principal-agent model is proposed.Finally,in order to curb the non-integrity behaviors of enterprises due to selfishness,an accountability mechanism is introduced to stimulate the integrity behavior of enterprises.
