%X 本研究基于2000~2020年亚洲48个国家和地区的数据&#65292;采用广义加性模型(GAM)&#65292;探讨了人均国民总收入(GNI<sub>pc</sub>)、城市人口率(UPR)和细颗粒物(PM<sub>2.5</sub>)浓度与预期寿命(LE)的非线性关系。研究发现&#65306;(1) 在时间尺度上&#65292;GNI<sub>pc</sub>与LE呈现稳定的非线性关系&#65292;而UPR和PM<sub>2.5</sub>与LE的关系未表现出显著的线性或非线性特征&#65307;(2) 在空间尺度上&#65292;亚洲不同地区的GNI<sub>pc</sub>、UPR和PM<sub>2.5</sub>对LE的影响存在显著差异。总而言之&#65292;社会经济因素和空气污染因素对预期寿命的非线性影响不容忽视。<br>This study, based on data from 48 countries and regions in Asia from 2000 to 2020, employs a Generalized Additive Model (GAM) to explore the nonlinear relationships between per capita gross national income (GNI<sub>pc</sub>), urban population ratio (UPR), and fine particulate matter (PM<sub>2.5</sub>) concentration with life expectancy (LE). The research finds: (1) On a temporal scale, GNI<sub>pc</sub> shows a stable nonlinear relationship with LE, whereas UPR and PM<sub>2.5</sub> do not exhibit significant linear or nonlinear characteristics with LE; (2) On a spatial scale, the impacts of GNI<sub>pc</sub>, UPR, and PM<sub>2.5</sub> on LE vary significantly across different regions of Asia. In summary, the nonlinear impacts of socioeconomic factors and air pollution on life expectancy cannot be overlooked.
