Attracted widespread attention from stakeholders, environmental information disclosed by companies can show the situations that corporates fulfill their environmental obligations. Different corporate stakeholders usually pay diverse attention to key environmental information factors due to their various industries, investment levels, identity characteristics, etc. However, the previous researches are not scientific enough due to the lack of reflecting the importance of environmental information according to the preferences of stakeholders. To fill this gap, this paper applies a fuzzy analysis model as the internal type‐2 trapezoidal fuzzy numbers —analytic hierarchy process (AHP) based ordinary least square regression to comprehensively reflect the preferences of stakeholders. Following that, this paper utilizes the data from 62 Chinese power companies as an example, and the results show that environmental information disclosed (EID) quality is positively correlated with regional economic development level and executive salary incentives. Moreover, the corporate political connection weakens the interaction between salary incentives and EID, which can be further confirmed by robustness analysis. Finally, this paper contributes to the literature on the research methods on EID by considering stakeholders’ preferences in the fuzzy environment.
