China has enhanced its actions on climate change,including the intention to lower 2030 carbon intensity by 60%~65% from 2005 levels.One the one hand,we should admit that the corresponding technical efficiency is dramatically different when completing the same reduction rate of carbon emissions in different regions given the diversity in regional energy conservation foundation and economic development.On the other hand,the energy efficiency and energy saving potential is also different across sectoral levels.The CO_2 emission reduction target for different regions will directly affect regional industrial structure adjustment and the strategy of different energy production and consumption.Therefore,it is worthwhile to build the scientific distribution mechanism for each region and sector under a 2030 emission reduction target.In order to answer the above questions we combined the principle of input-output table with ZSG-DEA modeling to analyze the pathway to Chinese regional emission reduction in 2030.We found that different sectors and regions have their own emission reduction pathways under the 2030 national carbon emissions reduction targets.For northern and eastern coasts and central regions,the emission reduction targets in 2030 will be stricter than ever.Furthermore,the reduction target of several energy-intensive sectors,such as the mining and non-metallic mineral products industries,will exceed national average standards,which means these sectors need to make more efforts to shift towards low carbon development.Overall,the INDC target has a positive effect on the decrease in carbon intensity for each region in China.
