Based on distance algorithm which is the strong efficient frontier minimum, the paper applies three-stage DEA model to estimating the efficiency of industrial CO2 emissions in China’s 30 provinces in 1998—2013. The advantage of this approach is that closer targets inputs and outputs of the inefficient units determine less demanding levels of operation to perform efficiently. On this ba-sis, the paper analyzes the efficiency of industrial carbon emissions regional differences and spatial autocorrelation, and learns from the gravity model to analyze the dynamic trajectory of the center of gravity of China’s industrial carbon emissions efficiency;finally, it uses the spatial panel data of China’s 30 provinces from 1998 to 2013, establishes the spatial panel data model, and affects the empirical re-search on the efficiency of China’s industrial carbon emissions influence factors. The results show that, except those in a few years, the efficiency of industrial carbon emissions in China and the regions has emerged to rise to varying degrees and there are regional differ-ences;Chinese provincial industrial carbon emission efficiency on the spatial distribution showed a strong positive correlation and spa-tial agglomeration characteristics;energy structure, energy intensity, industrial structure, the level of energy prices and technology are the main factors affecting the efficiency of Chinese industrial carbon emissions.
