Abstract：Improving the technological innovation capability is the key to achieving high-quality development of Chinese mining economy. This research selects five major mining industries： coal mining and processing， oil and gas mining， ferrous metal mining and dressing， non-ferrous metal mining and dressing， and non-metallic mining and dressing， as the research objects， and constructs a panel dataset from 2011 to 2019. The efficiency of the technological innovation efficiency of Chinese major mining industries is comprehensively evaluated and optimized during the study period based on the two-stage DEA-BCC model and the Malmquist index model. The research results show that the output efficiency in the oil and natural gas extraction industry as well asthe ferrous metal mining and dressing industry is far higher than the conversion efficiency. The uneven development of Chinese mining industry is more prominent， and the distribution of category I industries is lacking. The decline in total factor productivity of the mining industry is mainly due to the “dragging effect” brought about by technical efficiency， and there are significant timing differences and “partial science” phenomena in total factor productivity changes. Besides， there are redundant input and insufficient output in mining industries， and its input needs to be reasonably configured to achieve efficient output. The high-quality development of the mining industry should be promoted in terms of reducing excess capacity， enhancing industrial technological innovation capabilities， and creating a good industrial technological innovation atmosphere.
