摘要
随着电子商务的迅猛发展，商品评价与信誉体系作为影响消费者决策和平台信任的关键因素，已成为学术界和产业界关注的核心问题。本研究旨在深入探讨电子商务平台中商品评价机制的设计及其对用户行为和平台信誉的影响，并提出一种基于多维度分析的改进型信誉评估模型。研究采用混合方法设计，结合定量数据分析与定性案例研究，通过收集某大型电商平台的用户评价数据并进行文本挖掘和情感分析，揭示了现有评价体系中存在的信息不对称、恶意评价及评价偏差等问题。同时，基于用户访谈和专家咨询，进一步验证了模型的可行性和有效性。研究结果表明，改进后的信誉评估模型能够更全面地反映商品和服务的真实质量，显著提升用户满意度和平台信任度。本研究的主要创新点在于将用户行为特征与动态权重算法融入信誉评估体系，从而提高了评价结果的客观性和准确性。此外，研究还为电商平台提供了优化评价机制的具体建议，有助于构建更加公平透明的交易环境。总体而言，本研究不仅丰富了电子商务领域的理论框架，也为实践应用提供了重要参考价值。

Abstract
With the rapid development of e-commerce, product reviews and reputation systems have become key factors influencing consumer decision-making and platform trust, drawing significant attention from both academia and industry. This study aims to explore the design of product review mechanisms in e-commerce platforms and their impact on user behavior and platform credibility, proposing an improved reputation evaluation model based on multidimensional analysis. A mixed-methods approach was adopted, integrating quantitative data analysis with qualitative case studies. By collecting user review data from a large e-commerce platform and conducting text mining and sentiment analysis, this research revealed issues such as information asymmetry, malicious reviews, and review bias within the existing system. Additionally, user interviews and expert consultations were conducted to further validate the feasibility and effectiveness of the proposed model. The results indicate that the enhanced reputation evaluation model can more comprehensively reflect the true quality of products and services, significantly improving user satisfaction and platform trust. A major innovation of this study lies in incorporating user behavioral characteristics and dynamic weighting algorithms into the reputation evaluation system, thereby enhancing the ob jectivity and accuracy of review outcomes. Moreover, specific recommendations for optimizing review mechanisms are provided to e-commerce platforms, contributing to the establishment of a fairer and more transparent trading environment. Overall, this study not only enriches the theoretical fr amework of e-commerce but also offers valuable practical implications.
