A DEA-based improvement of China's green development from the perspective of resource reallocation

摘要

As the current important environmental management method in China, the green development concept aims to improve the environmental development status of the region from the perspectives of energy conservation, emission reduction, and pollutant control. Based on the concept of green development, we mainly consider the allocation of resources and the distribution of emission rights from the perspective of resource allocation and improve the efficiency of green development. We analyze how to allocate the additional fixed assets investment and emission rights to each province. We determine that the government should prioritize the faster economic growth areas when there is enough additional investment Some coastal areas are not priority allocation regions, indicating that their development has basically reached saturation. We also investigated the emission rights of "three wastes" of 30 provinces in China. The result shows that only Shanghai, Sichuan, Guangxi, and Gansu are affected by three wastes emissions after the allocation of additional resources, and their emissions of those three wastes are all reduced. Finally, we dynamically analyze the amount of resource reallocation between different regions under different growth (reduction) rates of fixed resources and emission rights while ensuring maximum overall efficiency. Eventually, we obtained the optimal investment increase and emission reduction by the algorithm.
