Abstract

Understanding the experiences and attitudes of electric vehicle (EV) owners is crucial for driving EV sales and thus promoting a sustainable environment. Previous studies have used costly and inflexible crowdsourced questionnaires to assess EV owner satisfaction. This study adopts an innovative approach by analyzing 41 h of video interviews with 2101 EV owners from a short video platform. Utilizing the Latent Dirichlet Allocation (LDA) model, topics of concern for EV owners were identified, followed by sentiment analysis supported by a large language model (LLM) and random forest model. The results indicate that 1) “After-sales & Brand (19.75 %),” “Performance Experience (25.63 %),” “Functionality & Comfort (31.76 %),” and “Car Cost (22.86 %)” are the four main concerns of EV owners. Notably, concern for car costs is rising, while after-sales service is decreasing. 2) While EV ownership is mostly male, female owners exhibit a higher percentage of positive sentiment, with 47.16 % compared to 36.81 % for male owners. 3) “Functionality & Comfort” is the key satisfaction factor for both genders, then women prioritizing “After-sales and Brand” and men prioritizing “Performance Experience” as secondary concerns. This study proposes a new research framework and empirical case based on short-video data, offering valuable insights for potential consumers and automakers.

电动汽车怎么样？通过网络短视频感知业主的体验和态度

了解电动汽车（EV）车主的体验和态度对于推动电动汽车销售，从而促进可持续发展环境至关重要。以前的研究使用昂贵且不灵活的众包问卷来评估电动汽车车主的满意度。本研究采用创新的方法，对短视频平台上2101名电动汽车车主进行了41小时的视频访谈。利用潜在狄利let分配（Latent Dirichlet Allocation， LDA）模型，识别电动汽车车主关注的话题，并在大语言模型（LLM）和随机森林模型的支持下进行情感分析。结果表明：1)“售后&；品牌（19.75%），“性能体验（25.63%）”，“功能&；“舒适性”（31.76%）和“汽车成本”（22.86%）是电动汽车车主最关心的四个问题。值得注意的是，对汽车成本的担忧正在上升，而售后服务却在减少。2)尽管电动汽车车主以男性为主，但女性车主对电动汽车持积极态度的比例更高，为47.16%，而男性车主为36.81%。3)“功能&；“舒适性”是男女满意度的主要因素，女性优先考虑“售后和品牌”，男性优先考虑“性能体验”。本研究提出了基于短视频数据的全新研究框架和实证案例，为潜在消费者和汽车制造商提供了有价值的见解。

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
