In the context of the era of economic green transformation, enterprises face greater litigation risks, and the opening of the asset market has an important impact on the internal decision-making and control of enterprises under green ecological development. In this paper, the enterprises listed in Shanghai and Shenzhen are selected as research samples, and the explanatory variables, interpretive variables, mediating variables, and control variables are selected for the study. The double difference model is used to construct an empirical model between the variables to explore the relationship between corporate litigation risk and asset opening under green ecological development. The study shows that the correlation coefficients between corporate asset openness (x) and corporate litigation risk dummy variables and numerical variables under green ecological development policy are -0.078 and -0.088, respectively, which are significantly negatively correlated at the 1% level. The robustness test validates this empirical result, indicating a strong correlation between the two. It has also been found that corporate asset openness has a greater negative effect on the litigation risk of heavy-polluting enterprises and state-owned enterprises. The study of enterprise litigation risk and asset opening is rethought in this paper, and it provides a reference basis for the effective management of enterprises under green ecological development.
