Abstract：Nearly 70％of China's carbon emissions come from coal,and technology is the key to achieving the"dual carbon"goals.By using the DEA-Tobit model,in order to clarify the current situation of technological innovation in emission reduction and carbon reduction in China's coal industry,the benefits of technological innovation in emission reduction and carbon reduction of 20 listed coal enterprises in China from 2018 to 2022 were evaluated,and the influencing factors were explored.The research findings are as follows:① Currently,the overall performance of technological innovation benefits of listed coal enterprises in China is relatively good.The benefit values are evenly distributed between 0.8 and 0.9,and the growth rate over the past five years is 11.86％.② The R & D investment in emission reduction and carbon reduction technologies of listed coal enterprises in China has all shown an upward trend,and the investment in R&D funds has a lag effect on the high-quality development of enterprises.③ Industrial structure and enterprise scale have a positive promoting effect on the technological innovation benefits of enterprises,while human resource structure has a negative inhibitory effect on the technological innovation benefits of enterprises.The research can provide decision-making basis for coal enterprises to enhance emission reduction and carbon reduction technologies and promote the achievement of the"dual carbon"goals.
