Abstract
Haze pollution poses a serious threat to residents’ health. In this study, a spatial econometric model of environmental health was
established to investigate the direction, intensity, and spatial–temporal heterogeneity of the impact of haze pollution and its spillover
effects on public health in 26 cities of the Yangtze River Delta urban agglomerations from 2005 to 2018. The study found that (1)
PM2.5 pollution and public health level all show the characteristic of positive spatial correlation and spatial clustering. (2) Haze
pollution is the main influencing factor of residents’ public health level, with significant negative effects and obvious spillover
effects. The urbanization rate, the number of health technicians, and the green area per capita have significant positive impacts
on public health. (3) The spatial and temporal heterogeneity of the impact of haze pollution and other factors on public health is
obvious. The negative correlation between PM2.5 pollution and public health in eastern cities is higher than that in other cities.
Both urbanization rate and green area per capita have a greater positive impact on public health in the northeast of the Yangtze
River Delta region. The improvement effect of the number of health technicians on the public health is stronger in the cities of
Anhui Province. The research results of this paper provide certain support for the city governments to formulate targeted policies.

Introduction
For a long time, people have paid attention to economic
growth but neglected the value of environmental resources,
even at the expense of the environment to a certain extent,
resulting in increasingly prominent environmental pollution
problems. In the last decade, the cost of environmental pol-
lution control in China has reached 10% of GDP (Liu etal.
2017; Zeng etal. 2019b). As the largest developing country,
the serious air pollution problem faced by China has become
one of the major threats to the health status of the residents
(Guan etal. 2016; Hunter, 2020). Global Burden of Dis-
eases, Injuries, and Risk Factors Study reveals that PM2.5
ranks sixth among the level 4 of mortality risk factors (Mur-
ray etal. 2020). Despite the remarkable results of the imple-
mentation of China’s “Air Pollution Prevention and Control
Action Plan (2013–2017),” there are still 17 provinces where
PM2.5 concentrations are not up to standard (Zheng and Xu,
2020). Numerous studies have confirmed that long-term
exposure to PM2.5 pollution is associated with higher rates of
COVID-19 transmission and mortality (Vasquez-Apestegui
etal. 2021; Wu etal. 2020). Severe haze pollution is expos-
ing people to major health risks. Moreover, the mobility of
air makes the externality of pollution even more significant,
and the regional pollution characteristics are obvious (Wang,
2014). It becomes very meaningful to consider the spatial
