Considerable data-enabled user experience has also recently become a significant development area. This study collected data from Alibaba users through a close-ended questionnaire. The model revealed that personalized recommendation, user experience, and target marketing strategies are significant predictors of consumer green satisfaction, and green purchase behaviour recommendations, user experience, and target marketing strategies are significant predictors of consumer green satisfaction and green purchase behaviour. Although targeted pricing could not find any significant relation with green purchase behaviour, it is mediated through green satisfaction. Overall, consumer green purchase behaviour can be enhanced through big data and its implications through targeted marketing, personalized recommendations, and user experience.
