摘要：
Regional low-carbon efficiency calculation and spatial differentiation evaluation are an important basis for formulating differentiated emission reduction measures. As a "clean energy demonstration province", Sichuan province shall make active contribution to carbon neutrality based on its own advantages in resource endowment. In order to calculate the low-carbon efficiency of Sichuan province from the perspective of carbon neutrality, this paper adopts the Undesirable-Super-SBM model and introduces forest carbon sequestration and technological innovation into the evaluation index system. Then, based on the panel data containing more degrees of freedom and sample variability, the low-carbon efficiency of Sichuan province and its internal 21 cities (prefectures) during 2005-2019 were calculated. Finally, the spatial differentiation of low-carbon efficiency between different regions was researched and determined by virtue of GIS spatial analysis technology. And the following conclusions are reached. First, the low-carbon efficiency of Sichuan province during 2005-2019 presents a trend of overall rising. Second, Chengdu has a high level of economic development, a reasonable industrial structure and a steady increase in forest coverage. Heavy industrial cities such as Panzhihua and Deyang are focusing on the green transformation of high energy consumption and heavy pollution industries, and have achieved remarkable results in energy conservation and emission reduction. They are the first-mover advantage regions of low-carbon transformation. Third, Zigong, Mianyang, Suining, Leshan and other regions have advantages in terms of national policy support and energy conservation and emission reduction space, and they are the development regions of low-carbon transformation, but in the future, they shall seek new growth points on the basis of traditional pillar industries. Fourth, Aba Tibetan and Qiang Autonomous Prefecture and Ganzi Tibetan Autonomous Prefecture have a harsh ecologic environment and low development level, and Dazhou and Ya'an are weak in geographical advantage without sufficient endogenous motivation for transformation, so they are the potential regions of low-carbon transformation. © 2021, Natural Gas Industry Journal Agency.
