The influence of informal institutions such as history and culture on corporate behavior has been widely recognized, but few studies have been analyzed from the perspective of the ruling party culture. Based on the data of the old revolutionary base areas (ORBA) in China, this paper makes an empirical test on the role of Red Culture in promoting enterprises green innovation. First, this paper finds that the stronger the Red Culture in the region where the enterprise is located, the higher the level of green innovation.Secondly, in the samples with high political sensitivity and less cultural conflict, the promoting effect of Red Culture is more obvious. This paper not only expands the relevant literature on the influence of informal system on enterprise green innovation, but also enriches the research on the influence of Chinese unique culture on enterprise management decision-making.

The study explores the impacts and processes of traditional Confucianism on the green technology innovation behavior of organizations from the perspective of the informal system, using samples of Chinese A-share listed companies from 2003 to 2022. The findings indicate that Confucianism has a significant promotional effect on green technological innovation, which remains robust after using the cross-multiplier term between the number of regional Confucius temples and the mean ESG of firms as an instrumental variable to mitigate the endogeneity problem and a series of tests. According to mechanistic research, Confucianism works largely through two channels: reducing agency conflicts and raising environmental consciousness. Further investigation reveals that there is a substitution impact between Confucianism in the informal institution and environmental legislation in supporting green technology innovation in firms. To encourage green technological innovation in enterprises, it is critical to emphasize the integration of informal and formal systems, as well as to fully use traditional culture’s governance efficacy in supporting the enterprise green transformation.
