Land is the Mother of Grain:Does High-standard Farmland Construction Increase Grain Yield Per Unit Area?
As an important policy implementation of"grain storage in land and technology"strategy,high-standard farmland construction is expected to effectively increase grain production and better ensure national food security.Based on the panel data of 27 provincial regions,this paper explores the impact and mechanism of high-standard farmland construction on grain yield per unit area.The results are as follows:(1)High-standard farmland construction can significantly increase grain yield per unit area.After different robustness tests,such as replacing variables,non-parametric estimation and controlling endogenous problems,this study still obtains a consistent conclusion.(2)Mechanism analysis shows that high-standard farmland construction can increase grain yield per unit area mainly through improving scale operation,promoting technological progress and reducing production risk.(3)Based on the heterogeneity analysis of geographical geomorphology,production positioning and economic level,it is found that the promotion effect of high-standard farmland construction on grain yield per unit area is greater in smaller terrain relief,major grain-producing areas and more developed areas.Therefore,this paper shows that high-standard farmland construction is indeed an important measure to consolidate the foundation of food security,and it should be steadily promoted in the future.
