| Abstract: |
| Based on panel data of 31 provinces in Chinese from 2013 to 2022, this paper measured the grain production resilience and utilized models such as the double fixed effects model and the Tobit model to examine the effect and mechanism of air pollution on the grain production resilience. The results indicated that: the average resilience of grain production in China has risen from 0.200 in 2013 to 0.260 in 2022, showing an overall upward trend. The average resilience in major grain producing regions has consistently been higher than the national average, while it is lower in major grain consuming regions and regions with balanced grain production and consumption. According to the Mann-Kendall trend test, between 2013 and 2022, the resilience of grain production in all provincial administrative units, except Heilongjiang, Liaoning, and Xinjiang, increases at a significance level of 5%. Air pollution significantly inhibits the grain production resilience. From a dimensional perspective, air pollution weakens the resistance and transformation capabilities of the grain production resilience. The digital economy plays a negative moderating role in the impact of air pollution on grain production resilience, as it weakens the adverse effect of air pollution on grain production resilience. Threshold analysis reveals that the negative impact of air pollution on the grain production resilience decreases as resilience increases, demonstrating a nonlinear characteristic. Heterogeneity analysis shows that air pollution has a stronger negative impact on the grain production resilience in major grain producing areas and temperate monsoon climate zone.Therefore, we should strengthen air pollution monitoring, and implement targeted air pollution control measures by region and industry. Additionally, the rural digital economy should be developed to promote the digital transformation of grain production. We should enhance infrastructure construction according to local conditions to optimize production conditions, enhance the resilience of grain production in major grain-producing areas, reduce sensitivity to air pollution, so as to ensure national food security and the implementation of the strategy for building an agricultural powerhouse. |
