Quantitative Evaluation and Dynamic Evolution of the Synergistic Effect of Agricultural Pollution and Carbon Reduction in China:An Analysis Based on Marginal Abatement Cost
Synergistic promotion of pollution and carbon reduction is the only way to accelerate the construction of a beautiful China and realize high-quality economic development Based on the synergistic effect of pollution and carbon reduction of agricultural sources,this paper constructs a quantitative assessment method of the effect from the perspective of marginal abatement cost,and empirically examines the agricultural pollution reduction effect,carbon reduction effect,and their synergistic effect at the national level,the nine agricultural region level,and the provincial level under the joint abatement of pollution from 1998 to 2021.The study draws the following conclusions:at the national level,the marginal pollution reduction cost and the marginal carbon reduction cost of agriculture under the joint emission reduction situation are both smaller than the cost of individual emission reduction,and there are positive pollution reduction and carbon reduction effects,while the two show a better synergistic trend.Among the nine major agricultural regions,except for the Qinghai-Tibet Plateau region and the Huanghuaihai Plain region,the synergistic effect of pollution and carbon reduction in the rest of the agricultural regions is prominent;the marginal costs of pollution and carbon reduction in South China are relatively lower,and there is greater potential for pollution and carbon reduction.At the provincial level,there are obvious differences in the pollution and carbon reduction effects among provinces,and both pollution and carbon reduction effects are increasing with the strengthening of environmental regulations.The expanded analysis reveals that the distribution and dynamic evolution of agricultural pollution and carbon reduction effects are characterized by significant regional and stage-specific features.The findings of this paper provide a policy basis for scientifically evaluating the potential of agricultural pollution and carbon reduction and formulating carbon and pollution synergistic management programs.
