Abstract: In this paper, by constructing multi-factor CES production function and transcendental function model including biased technological progress to empirically analyze the impact of China's energy-saving biased-oriented technological progress on economic growth ，and investigate different source technology progress factor bias and its economic growth effect. The study finds that: from 1991 to 2015, China's technological progress is generally biased toward capital and energy, bias towards capital-using , energy-using and labor saving. Element substitution elasticity is less than 1, energy-enhanced technology advances are manifested as energy-saving biased-type technological progress.The energy-saving biased-type technological progress promotes the improvement of total factor productivity through energy-enhanced technology progress index effect . The bias of technological advance from different sources and its economic growth effect are obviously different, the economic growth effect of independent innovation R&D is the highest, the economic growth effect of technological improvement is negative.The effect of biased technical progress on economic growth from different sources of technological progress is significantly greater than the effect of neutral technological progress on economic growth.
