基于商务Petri网的电子商务信誉度研究

针对电商交易中商家与电商平台之间的诚信问题，提出了一种商务Petri网理论。把Petri网与博弈论相结合，建立商务Petri网模型，分析商务Petri网模型中商家经营策略与电商平台不同监管措施之间的博弈关系，使用偏最小二乘法计算商家不同经营模式和电商平台监管模式下的信誉值。实验数据表明，电商平台监管和商家诚信经营时CR在2.5以上，EPC在95%以上|电商平台监管和商家欺诈经营时CR由0.2到0.02再到1.95，EPC从0.2降到0.01最后达到0.8。经过数据对比得出结论，商家选择诚信经营的效益永远大于欺诈经营效益，电商平台监管力度始终不能降低。

Research and Analysis of E-commerce Credibility Based on Business Petri Net

Abstract：In view of the integrity issue between merchants and e-commerce platforms in e-commerce transactions， we propose a business Petri net theory. In the paper， the Petri net and game theory are combined to establish a business Petri net model， and the game relationship between the business management strategy of the business Petri net model and the different regulatory measures of the e-commerce platform is analyzed. The partial least squares method is used to calculate the different business models of the merchant and calculate the reputation value under the e-commerce platform supervision mode. The experimental data shows that the e-commerce platform supervision and business integrity management CR was above 2.5， EPC was above 95%. The e-commerce platform supervision and merchant fraud operation CR was dropped from 0.2 to 0.02 to 1.95， EPC from 0.2 to 0.01 and finally reached 0.8. After data comparison， it concludes that the benefits of merchants choosing integrity management are always greater than the benefits of fraudulent operations and the supervision of e-commerce platforms can not be reduced.
