Can High-standard Farmland Construction Prevent the"Non-grain"Use of Cultivated Land?
Taking the policy of constructing high-standard farmland as a natural experiment,a continuous differential model was con-structed to investigate the impact and mechanism of high-standard farmland construction on farmland"non-grain"based on provincial panel data.The results have shown that compared to the control group,the construction of high standard farmland reduced the degree of"non-grain"of farmland in the experimental group by 3.64％,indicating that the construction of high standard farmland has a signifi-cant and sustained inhibitory effect on the"non-grain"of farmland.After model applicability and multiple robustness tests,the results are still reliable.The effect of this policy varies significantly due to differences in regional grain functional positioning,grain maturity,types of grain crops and terrain conditions.The inhibitory effect of high standard farmland construction on the"non-grain"of cultivated land is more pronounced in major grain producing areas,high maturity areas,rice planting areas,and non plain areas.Moreover,the expansion of land plots,changes in planting patterns,and comparative cost advantages are three important ways to prevent the"non-grain"of farmland through the construction of high standard farmland.Therefore,in the process of building a strong agricultural coun-try,we should accelerate the new round of high-standard farmland construction and make up for the shortcomings in farmland quality as soon as possible.At the same time,we should strictly implement the priority order of high standard farmland utilization,completely re-verse the trend of"non-grain"of arable land,and provide support for achieving the strategic goal of"Storing Food in Land".
