With the development of 10 years, green food is more and more widely known in China. Nowadays, green food has become synonymous with healthy food. With China's entry into WTO and the development of global economic integration, and China's transformation from a "well-off" society to a "well-off" society, people's lifestyles are changing, and the requirements for agricultural products and food quality are getting higher and higher, especially for pollution-free food and green food. Although the demand of consumers is increasing, it can be seen from the existing literature that the market share of green food is still very limited, and the green food market is still seriously short of consumers. The consumption market of green food mainly depends on consumers' cognition, buying attitude and buying behavior of green food. Consumers' buying attitude directly affects their buying behavior. So what is the current consumer attitude towards green food? What are the main factors? And the relationship between consumers' attitude towards buying green food and their purchase intention? From the existing literature in China, there is little theoretical research and empirical analysis on consumers' behavior of buying green food, and even less research on the influence of consumers' lifestyle on their attitude and buying behavior. From the application point of view, studying and accurately understanding the factors that affect consumers' attitude and behavior to buy green food can help enterprises understand consumers' real needs more deeply and accurately, so as to formulate more effective marketing strategies; At the same time, it can also ... provide more decision-making reference for government agencies to formulate policies and regulations and guide healthy and scientific consumption behavior. This paper attempts to study and discuss consumers' attitude towards green food and its influencing factors from the perspectives of consumers' lifestyle, environmental concern, ecological cognition and price through empirical research. Based on the research of existing theoretical literature, this paper refers to and adapts the existing related attitude measurement scale, and determines the influencing factors. Taking Chongqing consumers as the research object, the first-hand data of consumers' attitudes, behaviors and lifestyles to buy green food are obtained through questionnaire survey, and 3 14 samples are recovered. By using the methods of reliability analysis, factor analysis, cluster analysis, one-way ANOVA, correlation analysis and regression analysis, this paper makes an empirical analysis of the relevant assumptions put forward in this paper. The results show that the main factors affecting consumers' attitude towards buying green food in Chongqing are: price, convenience, health awareness and environmental awareness; The conclusion also shows that there is a significant positive correlation between positive buying attitude and positive buying intention; Among the consumer groups grouped according to lifestyle, "leisure and healthy" consumers are the most active in buying green food. Finally, it summarizes the relevant research conclusions and shortcomings of this paper.
