Abstract: Abstract In recent years, the development of urbanization and industrialization has produced many negative effects on ecosystem and human health, such as global warming, air pollution, environmental noise, urban garbage and biodiversity loss. Many researchers have conducted extensive research on pro environmental behavior from the perspectives of economics, sociology, psychology and anthropology. The pro environmental behavior involves not only the behavior of environmental protection in the personal field, but also the behavior of promoting environmental protection related issues by initiating or participating in environmental protection social organizations in the public field. At the same time, pro environmental behavior is also the behavior that individuals consciously show beneficial to the environment based on certain values, world outlook and sense of responsibility.The formation of Pro environmental behavior should be interpreted not only from the perspective of individual cognition, but also from the perspective of group cognition. Previous studies on pro environmental behavior mostly analyzed the causes and psychological mechanism of pro environmental behavior from the perspective of individual, and explained pro environmental behavior from the perspective of individual cognitive process. In real life, most of the environmental events originate from human group's non environmental behavior, and these environmental events have brought many negative effects on people's physical and mental development. Few studies explain the generation mechanism of pro environmental behavior from the perspective of social groups. Therefore, it is necessary to expand the previous theoretical framework of exploring pro environmental behavior only from the individual perspective, interpret pro environmental behavior from a broader group perspective, reveal the occurrence mechanism of pro environmental behavior at the group level, and carry out intervention guidance, which can not only enhance people's psychological explanation of effectively coping with global environmental events, but also promote people's positive environmental protection protect behavior and realize effective environmental governance.The environmental crisis caused by the destruction of ecological environment has posed a serious threat to the sustainable development of human society. Seeking positive environmental governance countermeasures, promoting people's pro environmental behavior, constructing the "co construction, sharing and co governance" environmental governance system, and improving the quality of human life have become the most urgent global social governance issues. Based on the two theoretical perspectives of pro environmental behavior, this paper introduces the social identity model of pro environmental behavior, and emphasizes to explore the generation mechanism of pro environmental behavior from the perspective of group social identity. Based on the in-depth discussion of the relationship between inner group identity, inner group norms and goals, collective efficacy, emotion and motivation and pro environmental behavior in the process of social identity, this paper puts forward a social psychological approach to promote pro environmental behavior, hoping to change the public's negative participation in environmental governance, promote people's pro environmental behavior, and promote the harmonious coexistence of human and environment coexistence development provides policy basis, but also provides a new governance path for global environmental governance.

摘要： 摘 要 亲环境行为是个体以一定的环境价值观为基础而表现出来的对环境有利的行为。亲环境行为如何生成不仅要从个体的认知视角去解读，也要从群体认知的视角去阐释。亲环境的社会认同理论提供了一条从群体层面探究亲环境行为生成机制的新路径，通过对社会认同过程中内群体认同、内群体规范与目标、集体效能感、情感与动机等与亲环境行为关系的深入探讨，提高了对亲环境行为的理论解释框架，为全球性环境治理提供了新的治理路径。
