摘　　要：本文基于中国健康与养老追踪调查数据,实证分析了高温对中老年人认知能力的影响。相对于青年群体来说,中老年人是社会经济决策的主要群体,因此他们的认知水平稳定对于家庭与社会发展至关重要。研究发现高温对于中老年人的认知不仅具有显著负向影响,还具有短期的滞后效应。此外,异质性分析结果表明北方中温带地区的农村中年女性更易受到高温的负面影响。本文提供的高温对中老年认知影响证据可为政府采取积极措施应对极端高温频发的趋势,提升中老年人健康水平提供科学依据。Based on the data from China Health and Retirement Longitudinal Survey,this study analyzes the impact of heat stress on the cognitive ability of middle-aged and elderly cohorts,who are major decision makers in social-economic affairs.Therefore,the stability of their cognitive level is crucial.It is found that heat stress not only has a significantly adverse impact on the cognition of middle-aged and elderly cohorts,but also has a short-term lag effect.In addition,the heterogeneity analysis results show that middle-aged women in north mid-temperature rural areas are more vulnerable to the heat stress.The evidence on the negative impact of heat stress provides a scientific basis for government to take proactive measures to mitigate the impact driven by climate change and consequently improve the health of the middle-aged and elderly.
