Hotspot Research and Development Trend Forecast of Car-Sharing: A Bibliometric Analysis Based on CiteSpace

Car-sharing not only meets the diversified travel needs of people and reduces the number of private cars in urban areas, but also helps alleviate urban traffic congestion and improve the efficiency of urban resource allocation. This paper utilizes CiteSpace bibliometric tools to conduct a systematic visual analysis of English literature in the field of car sharing from 1999 to 2023, revealing the research hotspots and development trends within this domain. Through keyword co-occurrence analysis, key themes such as “car sharing,” “model,” “mobility,” and “systems” emerged, reflecting academic focus on car-sharing models, technological optimization, and integration within transportation systems. Since 2016, as the sharing economy and smart technologies have become more widespread, car-sharing research has significantly increased. This paper summarizes the primary research directions and hotspots in the car-sharing field, providing a theoretical foundation and reference for future research on sustainable shared mobility.
