Abstract Due to the continuous progress of constructing sustainable environments in China, the role played by the Chinese central government as the main body for promoting green development is worth studying. Because China’s ecological civilization building has been steadily progressing. Governments at all levels in China have prioritised the development of environmental civilization as a key aspect of regional growth. However, the actual impact and mechanisms of influence of this construction still require further investigation. This paper constructs a government environmental attention index using word frequency found in the Report on the Work of the Government. It uses a long difference model to study the impact and mechanism of government environmental attention on urban green efficiency, carbon emissions and air quality. The results show that the government’s ecological attention can improve green efficiency, and air quality, but it can also lead to increased carbon emissions, and the impact is particularly evident in the eastern and western regions of the country. This is because the government’s emphasis on the environment significantly impacts on environmental regulations and technological progress, and is directly influenced by fiscal bias and financial pressure. Given the results, we put forward some policy suggestions that local governments should improve the intensity of local environmental regulation, encourage green technology innovation, provide encouraging conditions for environmental development, and establish a long-term strategic vision. The findings in this study has implications for promoting the implementation of local governments’ environmental protection and the development of sustainable societies in China.
