基于SEM的电商卖家信用影响因素效应分析
首发时间:2018-07-12
摘要:电商平台根据卖家获得的好评数评定卖家星级。然而,买家的评价详情与评价结论往往存在不一致,评价结论具有一定的主观性,由此确定的卖家星级不能真实反映卖家信用。以淘宝网鞋类卖家为例,分析影响卖家信用的可观测因素和潜在因素,选择卖家信用、描述相符和服务态度等9个因素作为可测变量,服务质量等3个因素作为潜在变量,建立初始的信用影响因素结构方程模型。收集150个鞋类卖家数据,运用AMOS软件,检验初始模型参数并进行模型修正。修正的模型拟合性好,验证了提出的假设,具有很好的解释能力。在此基础上,提出信用水平指数计算方法,为电商平台对卖家进行信用评级和买家购买决策提供参考。

Analysis of Effect of Factors Affecting E-commerce Sellers\' Credit Based on Structural Equation Model
Abstract:E-commerce platform rates the seller star based on the praise received by the seller. However, the buyer\'s evaluation details and the evaluation conclusion are often inconsistent, and the evaluation conclusion has certain subjectivity. Therefore, the star rating of the seller cannot truly reflect the seller\'s credit. Taking Taobao shoe sellers as an example, this paper analyzes factors that influencing the sellers \'credit and potential factors, and selects 9 factors as observable variables, such as seller\'s credit, description of conformity and attitude of service, and three factors, such as service quality, are used as latent factors, and an initial structural equation model of credit influencing factors is established. Collecting 150 shoe seller\'s datas, using AMOS software, testing the initial model parameters and model modifications. The modified model fits well, which verifies the proposed hypothesis and has good explanatory power. On this basis, a method of calculating the credit rating index is proposed, which provides a reference for the seller\'s credit rating and buyer\'s purchasing decision.
