Research on the Evolution of China’s E-Commerce Policy Based on Text Mining

互联网产业的快速发展，也给电子商务产业带来了新的发展机遇。政策作为引导电子商务产业发展的重要影响因素，揭示了电子商务政策的演化路径对电商产业的发展具有重要意义。本文基于政策生命周期理论，对从中国政府网、国家发改委和商务局官方网站上收集到的345份电子商务政策进行生命周期划分，共划分了三个阶段，利用LDA主题模型提取各个阶段的政策主题，并结合Word2Vec词向量模型对其进行主题相似度计算，构建了我国电子商务政策的演化路径。研究发现，我国电子商务政策呈现从基础建设到体系优化，再到产业融合的渐进发展路径，且重点在于关注农村电子商务和农产品跨境电子商务两大产业领域。The rapid development of the Internet industry has also brought new development opportunities to the e-commerce industry. Policy, as an important influencing factor guiding the development of the e-commerce industry, reveals the evolution path of e-commerce policies, which is of great significance to the development of the e-commerce industry. Based on the policy life cycle theory, this paper divides the life cycle of 345 e-commerce policies collected from the official websites of the Chinese government, the National Development and Reform Commission, and the Commerce Bureau into three stages. The LDA topic model is used to extract the policy topics of each stage, and the Word2Vec word vector model is combined to calculate the topic similarity. The evolution path of e-commerce policies in China has been constructed. Research findings indicate that China’s e-commerce policies follow a progressive development path from infrastructure construction to system optimization and then to industrial integration, with a focus on two major industrial fields: rural e-commerce and cross-border e-commerce for agricultural products.
