Environmental problems are urgent problems in the process of high-quality development in the new era.It is generally believed that it is necessary to improve the level of technological innovation, adjust industrial structure and strengthen environmental regulation.From a new perspective outside of production activities, this paper studies the impact of mixed economic growth objectives, public participation and interaction items on the environment.It is found that the mixed economic growth target has an inverted u-shaped relationship with environmental pollution, that is, the mixed economic growth target first aggravates environmental pollution, and then improves environmental quality.Letters and telephone complaints from the people"s congress and the CPPCC did not significantly curb environmental pollution.Public participation has not improved the environment because of mixed economic growth targets.The theoretical and empirical results of this paper show that the mixed economic growth target deteriorates the environment to some extent and leads to the failure of public participation, which plays an important role in further adjusting the economic growth target and improving the public participation system.
