绿色技术创新对建筑业碳排放效率的影响OA

Green technology innovation is considered to be an effective channel to balance economic growth and environmental governance.Based on the panel data of 30 provinces in China from 2010 to 2021,the SBM model was used to estimate the carbon emission efficiency of each province.Two-way fixed effect regression model and intermediary effect model were used to analyze the internal relationship between green technology innovation and carbon emission efficiency of construction industry.The results show that:there is a positive correlation between green technology innovation and the carbon emission efficiency of the construction industry,and green technology innovation can significantly improve the carbon emission efficiency of the construction industry in the eastern and central regions.Environmental regulation and upgrading of industrial structure have mediating effect between green technology innovation and carbon emission efficiency of construction industry.The total output value,R&D intensity and economic development level of the construction industry are positively correlated with the carbon emission efficiency of the construction industry,while the urbanization level and opening-up degree are negatively correlated with the carbon emission efficiency of the construction industry.On this basis,combined with the empirical research results,the relevant policy recommendations are put forward.
