基于文本分析的电商平台隐私政策合规性研究

Research on the Compliance of Privacy Policies of E-Commerce Platforms Based on Text Analysis

摘要: 随着《个人信息保护法》的实施，电商平台隐私政策的合规性成为关注焦点。本研究选取国内十家主流电商平台，采用LDA主题模型与内容分析法，结合《个保法》等法律法规，从主题分布与条款合规两个维度对其隐私政策展开系统性评估。研究发现：平台隐私政策普遍存在形式合规与实质合规的落差，用户权利保障维度表现薄弱，撤回同意权与账号注销权的实际合规率均低于50%，数据跨境传输告知成为共性短板。不同商业模式平台的隐私政策侧重差异显著，内容型电商在服务功能说明上篇幅突出但权利保障不足，综合型平台则面临新兴合规要求的挑战。研究提出，需通过细化监管指引、优化文本设计、强化动态评估，推动隐私政策从文本规范转向实质保护。

Abstract: With the implementation of Personal Information Protection Law, the compliance of e-commerce platform privacy policies has drawn increasing attention. This study selects ten major domestic e-commerce platforms and employs LDA topic modeling and content analysis to systematically evaluate their privacy policies from two dimensions: topic distribution and clause compliance, in accordance with relevant laws and regulations. The findings reveal a widespread discrepancy between formal and substantive compliance in platform privacy policies, with particularly weak performance in user rights protection. The actual compliance rates for the right to withdraw consent and the right to account cancellation are both below 50%, while cross-border data transfer notifications emerge as a common deficiency. Privacy policies of platforms with different business models exhibit distinct emphases: content-oriented platforms allocate significant space to service function descriptions but inadequately address rights protection, whereas comprehensive platforms face challenges in meeting emerging compliance requirements. The study proposes that refining regulatory guidelines, optimizing text design, and strengthening dynamic evaluations are essential to shift privacy policies from textual standardization to substantive protection.
