数字孪生在智慧交通领域的网络关注时空演化分析——基于百度指数的视角

Analysis of the Spatio-Temporal Evolution of Online Attention to Digital Twins in Intelligent Transportation—An Analysis Based on Baidu Index

摘要: 本文基于百度指数研究数字孪生和智慧交通的网络关注时空演变过程，以公众的视角从宏观层面掌握数字孪生和智慧交通的社会认知状况，为数字孪生在智慧交通中的应用提供重要的市场和社会洞察。研究表明，近年来人们对数字孪生的关注大幅提升体现出较大的波动性，而对智慧交通的网络关注较为平稳。在资讯传播方面，智慧交通的资讯关注度明显高于数字孪生和数字孪生的传播度；地域分布上，华东、华北、华南位于前列，省份分布上北京、广东具有长期优势，对周边省份具有一定的带动性；城市分布上北京、上海领先优势明显。关注人群的年龄分布上，20~50岁的群体较为活跃，其中20~40的群体对数字孪生的关注人数最多，性别分布上，男性关注人数多于女性，这一差异在关注数字孪生的群体中表现更为突出。关注内容分布上，主要集中于数字孪生的技术实现以及智慧交通的应用实现方面。

Abstract: This article studies the spatio-temporal evolution process of online attention to digital twins and smart transportation based on Baidu Index, aiming to understand the social recognition status of digital twins and smart transportation from a macro perspective and provide important market and social insights for the application of digital twins in smart transportation. The research shows that in recent years, the online attention to digital twins has significantly increased with considerable fluctuations, while the attention to smart transportation has been relatively stable. In terms of information dissemination, the information attention to smart transportation is significantly higher than that to digital twins and the dissemination of digital twins. Geographically, East China, North China, and South China are at the forefront, and in terms of provincial distribution, Beijing and Guangdong have long-term advantages and have a certain driving effect on surrounding provinces. In terms of city distribution, Beijing and Shanghai have obvious leading advantages. In terms of the age distribution of the attention group, the 20~50 age group is more active, among which the 20~40 age group has the largest number of people paying attention to digital twins. In terms of gender distribution, the number of males is more than that of females, and this difference is more prominent in the group paying attention to digital twins. In terms of the distribution of attention content, it is mainly concentrated on the technical realization of digital twins and the application realization of smart transportation.
