Abstract:

An in-depth analysis of the new development concept’s impact on the definition of regional subject characteristics， as well as the scope of carbon emission rights and responsibilities， expands the connotations and boundaries of the principles of equity， efficiency， sustainability， and feasibility. A three-tier， 30-dimensional initial carbon quota allocation system is constructed， and the maximum deviation method is used to comprehensively measure regional differences and estimate the initial carbon quotas of China’s 30 provincial regions over the next 15 years， with performance evaluations conducted from the integrated dimensions of equity， efficiency， and emission reduction costs. The research results indicate that the new development concept has expanded the connotations and boundaries of existing distribution principles in areas such as regional coordinated development， factor flow allocation， social co-construction and sharing， and green low-carbon development. Changes in the definition of regional subject characteristics and the scope of carbon emission rights and responsibilities will significantly affect the distribution results of initial carbon quotas， thereby affecting the fairness， efficiency， and emission reduction costs of the distribution plan. The new plan can better reflect existing distribution principles and has better distribution performance. Regional characteristics such as ecological endowment and green sustainable development capabilities have a significant impact on the surplus and deficit of each region’s initial carbon quotas， which helps to promote regional green sustainable development and coordinated carbon reduction.
