Abstract: Based on the panel data of Northeast China from 2008 to 2019, the unfavorable output super efficiency SE-SBM model was used to calculate the total factor carbon emission performance, and the threshold panel model was used to analyze the threshold effect of green technology innovation on carbon emission performance, so as to explore the impact mechanism of industrial structure, economic development, trade opening, urbanization level and energy consumption structure on carbon emission performance. The results indicated that the overall carbon emission performance of Northeast China showed a steady upward trend and then a downward trend, and reached the peak in 2013. Green technology innovation had a double threshold effect on carbon emission performance, which showed a U-shaped relationship. Industrial structure and economic development could promote carbon emission performance. The degree of foreign trade, urbanization level and energy consumption structure had a negative impact on carbon emission performance. Therefore, Northeast China should improve the level of green technology innovation, optimize and upgrade the industrial structure and energy consumption structure, reasonably promote the process of foreign trade and urbanization, in order to advance the all-round revitalization of the northeast region.

Key words: Northeast China, green technology innovation, carbon emission performance, SE-SBM model, threshold effect
