Abstract:Based on the undesired output super-efficiency SBM model, this paper measures China’s provincial total factor carbon emissions efficiency from 2007 to 2016. Moreover, it analyzes spatial agglomeration characteristics and dynamic convergence on time axis of total factor carbon emissions efficiency by spatial autocorrelation analysis and dynamic convergence analysis method. From the perspective of regions, total factor carbon emissions efficiency decreases gradually from east to west and total factor carbon emissions efficiency of eastern regions is significantly higher than national average level. From the perspective of space, total factor carbon emissions efficiency shows obvious spatial agglomeration effect, which is characterized by H-H (high-high) and L-L (low-low) agglomeration. From the perspective of time, regional differences are narrowing and show?the characteristic of dynamic convergence. Finally, different carbon emissions reduction suggestions are put forward for different provinces
