中文摘要:

      随着移动互联网的快速发展，社交媒体日益成为公众表达对重污染天气等环境问题关注的工具。本研究以微博为例，探讨了社交媒体反映的环境关注对城市PM_2.5浓度水平的影响以及内在机制。研究发现，微博上环境关注的空间分布显示出向高等级和高污染城市聚集的倾向，PM_2.5浓度水平高的地区集中在煤炭资源或重工业集聚的地区。空间回归模型的结果证实了社交媒体的环境关注能显著降低PM_2.5浓度水平，层级较高的城市及创新能力较强的城市能够更好地回应社交媒体的环境关注，并有效降低城市的PM_2.5浓度水平。本研究表明，社交媒体的环境关注已经成为环境治理中的一种重要力量，在分析环境问题时应该充分考虑新兴社交媒体平台的影响。

英文摘要:

      With the rapid development of mobile Internet, people are increasingly using social media to express their concerns about environmental issues such as haze. This study explored the impact of environmental concerns reflected in social media on urban PM 2.5 levels and the underlying mechanisms of this impact using Weibo as an example. It was found that the spatial distribution of environmental concerns on Weibo showed a tendency to cluster toward high-ranking and high-pollution cities, with high PM_2.5 levels concentrated in areas where coal resources or heavy industries are agglomerated, and showed strong spatial auto-correlation. The results of the spatial regression model confirmed that environmental concerns from social media significantly reduce PM_2.5 levels, that higher-ranking and more innovative cities are able to better respond to environmental concerns from social media and effectively reduce urban PM 2.5 levels, and that financial burdens hinder the ability of cities to respond to environmental concerns to improve air quality. The study also confirmed the significant effects of industrialization, urbanization, and other socioeconomic factors on urban PM_2.5 levels. This study proposed a potential channel to influence environmental governance from the perspective of social media environmental concerns, showing that environmental concerns through social media have become an important force in environmental governance, and the influence of emerging social media platforms should be fully considered when analyzing environmental issues.
