摘　　要：跑鞋因其舒适性和多样性,已成为大众运动的热门选择,为了对跑鞋产品差异化竞争、市场策略制定和用户生态建设提供解决方案,本研究采用python环境下的潜在狄利克雷分布(Latent Dirichlet Allocation,LDA)模型,对2016—2023年京东平台10万条跑鞋用户评论文本做了主题挖掘与演化分析。通过主题关键词分布、关键词聚类热图、主题地域分布和主题演化探讨跑鞋产品市场存在的问题,并针对结果提出对策建议。研究发现,国产跑鞋在功能性设计方面有待提高,产品尚未形成多样性使用场景,消费者对跑鞋评论尚未形成体系。未来需重点从建立跑鞋功能与用户群体匹配系统、打造具有地域性特征的跑鞋产品、创建企业用户交互式跑鞋社群论坛3个方面着手,以优化产品研发和市场服务策略。Running shoes have become popular in mass sports because of their comfort and diversity.In order to provide solutions for differentiation competition,market strategy formulation and user ecological construction of running shoe products,Latent Dirichlet Allocation(LDA)model in the python environment was adopted.Topic mining and evolution analysis were made on 100000 user review texts of running shoes on Jingdong platform from 2016 to 2023,and the problems existing in the market of running shoes products were discussed through topic keyword distribution,keyword clustering heat map,topic regional distribution and topic evolution,and countermeasures and suggestions were proposed based on the results.It is found that the functional design of domestic running shoes needs to be improved,the product has not yet formed a variety of service scenarios,and consumers'comments on running shoes have not yet formed a system.In the future,it is necessary to focus on establishing a matching system between running shoe functions and user groups,creating running shoe products with regional characteristics,and creating an interactive running shoe community forum for enterprise users to optimize product development and market service strategies.
