| description | [Objective] As a key initiative of China’s national food security strategy, the policy of major grain-producing areas serves as an important tool for coordinating stable and increased grain production with green agricultural development. Systematically evaluating its effect on the synergistic reduction of agricultural pollution and carbon emission holds significant theoretical and practical significance. [Methods] This study treated the establishment of major grain-producing areas as a quasi-natural experiment. Using panel data from 31 Chinese provinces from 1997 to 2022, a difference-in-differences (DID) method was employed to empirically examine the policy’s effect on the synergistic reduction of agricultural pollution and carbon emission. [Results] (1) The policy of major grain-producing areas significantly promoted the synergistic reduction of agricultural pollution and carbon emission, with a series of robustness tests and instrumental variable estimations confirming the robustness of results. However, the policy effects exhibit heterogeneity across regions with different quantiles of agricultural pollution reduction and carbon mitigation synergy, varying degrees of rural population aging, and levels of agricultural labor transfer. (2) From the perspective of mechanisms, promoting large-scale agricultural operations, advancing agricultural technology, and adjusting the crop structure were effective pathways through which the policy of major grain-producing areas facilitated the synergistic reduction of pollution and carbon emission in agriculture. (3) Environmental regulation and fiscal support for agriculture played positive moderating roles in the process of promoting the synergistic reduction of agricultural pollution and carbon emissions by the policy of major grain-producing areas. (4) The policy of major grain-producing areas also generated additional socioeconomic benefits in the process of promoting the synergistic reduction of agricultural pollution and carbon emission, including ensuring food security, promoting agricultural economic growth, and improving employment levels in the agricultural sector. [Conclusion] The policy of major grain-producing areas can effectively promote the synergistic reduction of agricultural pollution and carbon emission. Therefore, it is recommended to further leverage the policy’s advantages, actively explore synergistic pathways and long-term mechanisms, and promote the synergistic reduction of agricultural pollution and carbon emission tailored to regional characteristics. |
