Do Chinese Residents' Perceptions of Air Pollution Affect Their Pro-Environmental Behaviors: The Moderating Role of Environmental Knowledge

Air pollution has become an important environmental and public health problem in China; improving air quality has become one of the most important tasks of the Chinese central government in recent years. In all aspects of environmental governance, the public's pro-environmental behavior is crucial to comprehensively improve air quality. This study used data provided by the 2021 China General Social Survey (CGSS) to explore the relationship between air pollution perception, environmental knowledge, and pro-environmental behavior. The results of the study indicated that: (1) Residents' subjective perception of air pollution has a significant positive impact on residents' pro-environmental behaviors. The more serious the air pollution in the surrounding area is, the more likely residents are to adopt more pro-environmental behaviors; (2) Environmental knowledge also has a positive impact on residents' pro-environmental behaviors and individuals with higher environmental knowledge are more likely to adopt more pro-environment behaviors; and (3) Environmental knowledge plays a positive regulating role in the relationship between air pollution perception and pro-environmental behavior. Individuals with higher environmental knowledge are more willing to engage in more pro-environmental behaviors when they perceive air pollution. To promote the residents' pro-environmental behaviors, we should further strengthen the education of environmental knowledge and strengthen the disclosure of environmental information. This study provides valuable insights for China to formulate environmental governance policies, enrich the research on pro-environmental behavior to a certain extent, and provide lessons for other developing countries and high-polluting countries to find environmental governance methods.
