摘要

此前的研究强调了高铁对个人身心健康的积极影响。然而，高铁扩张对卫生公平和整体城市卫生的更广泛影响仍不清楚。本文测量了2007 - 2019年中国284个城市的城市健康状况，并采用双机器学习模型分析高铁对城市健康的影响。我们进一步研究了城市间的潜在机制和区域异质性。结果表明，高铁的扩张显著提高了城市健康状况，特别是在中国东部和中部的发达城市。机制分析表明，绿色技术创新的增加、医疗资源配置的增强和经济活动的扩大在高铁服务与城市健康的关系中起中介作用。本研究有助于理解高铁发展如何影响城市健康，并为优化中国高铁网络以支持“健康城市”倡议提供有价值的见解。

How high-speed rail development empowers urban health: Evidence from Chinese prefectural-level data

Previous research has highlighted the positive effects of high-speed rail (HSR) on individual mental and physical health. However, the broader impact of HSR expansion on health equity and overall urban health remains unclear. This paper measures the urban health of 284 Chinese cities from 2007 to 2019 and employs a double machine learning model to analyze the effects of HSR on urban health. We further investigate potential mechanisms and regional heterogeneities across cities. The results suggest that HSR expansion significantly enhances urban health outcomes, especially in developed cities in eastern and central China. Mechanism analysis reveals that increased green technology innovation, enhanced healthcare resources allocation, and expanded economic activities mediate the relationship between HSR services and urban health. This study contributes to the understanding of how HSR development impacts urban health and provides valuable insights into optimizing China’s HSR network to support the “Healthy Cities” initiative.

期刊介绍： Transportation Research: Part A contains papers of general interest in all passenger and freight transportation modes: policy analysis, formulation and evaluation; planning; interaction with the political, socioeconomic and physical environment; design, management and evaluation of transportation systems. Topics are approached from any discipline or perspective: economics, engineering, sociology, psychology, etc. Case studies, survey and expository papers are included, as are articles which contribute to unification of the field, or to an understanding of the comparative aspects of different systems. Papers which assess the scope for technological innovation within a social or political framework are also published. The journal is international, and places equal emphasis on the problems of industrialized and non-industrialized regions. Part A''s aims and scope are complementary to Transportation Research Part B: Methodological, Part C: Emerging Technologies and Part D: Transport and Environment. Part E: Logistics and Transportation Review. Part F: Traffic Psychology and Behaviour. The complete set forms the most cohesive and comprehensive reference of current research in transportation science.
