Research on Impact of High-standard Farmland Construction on Grain Production Resilience——Based on Quasi-natural Experiment of High-standard Farmland Construction Pilot Policy
Grain security is the cornerstone of national security.In the current complex and changeable external environment,exploring the grain production resilience is particularly important.As an important policy practice of the"storing grain in the land and storing grain in technology"strategy,high-standard farmland construction is highly expected to achieve grain yield increase and ensure national grain security.Based on the quasi-natural experiment of high-standard farmland construction,the grain production resilience in 31 provinces across the country from 2000 to 2022 was measureed using the entropy method,and the impact of high-standard farmland construction on the grain production resilience was empirically tested using the multi-period difference-in-differences method.The study found that:the construction of high-standard farmland significantly improved the grain production resilience,and the conclusion was robust.Mechanism analysis showed that the construction of high-standard farmland improved the grain production resilience by promoting the internal path of agricultural social service,agricultural mechanization and cultivated land multiple cropping.The effect of high-standard farmland construction on the grain production resilience varied significantly among regions with different grain producing functional areas,topography,and human capital levels,and was more pronounced in grain production areas,regions with less topographic relief,and regions with higher human capital levels.Extensive analysis found that the impact of high-standard farmland construction on the grain production resilience had spatial spillover effects.The research conclusions provided a new perspective for exploring the path to enhance the grain production resilience in theory and empirical evidence for establishing and improving high-standard farmland construction in practice.
