摘　　要：技术创新是煤炭行业实现高质量发展的关键,技术创新效率对于技术创新起着决定性作用。采用DEA模型对2007—2019年中国大中型煤炭企业技术创新效率进行评价,分析结果显示,2007—2019年大中型煤炭企业技术创新效率保持较高水平,2007、2011、2013、2018、2019年综合技术效率达到DEA有效,2014—2017年出现投入冗余与产出缺口,说明提高资源配置效率对于提高技术创新效率十分重要,煤炭企业可以通过加快技术进步速度、提升行业科研人员创新能力来提高煤炭企业综合技术创新效率。Technological innovation is the key to achieving high-quality development in the coal industry,and technological innovation efficiency plays a decisive role in technological innovation.The DEA model was used to evaluate the technological innovation efficiency of Chinese large and medium-sized coal enterprises from 2007 to 2019.The analysis results show that the technological innovation efficiency of large and medium-sized coal enterprises maintained a relatively high level from 2007 to 2019.In 2007,2011,2013,2018,2019,the comprehensive technical efficiency reached DEA effective.The occurrence of input redundancy and output gap from 2014 to 2017 shows that improving the efficiency of resource allocation is very important for improving the efficiency of technological innovation.Coal enterprises can improve the overall technological innovation efficiency of coal enterprises by accelerating the speed of technological progress and improving the innovation ability of industry researchers.
