中文摘要:
      基于中国高标准农田建设政策分区域推进的准实验条件,利用2006-2017年中国30个省份的平衡面板数据,运用双重差分模型实证检验了高标准农田建设政策对粮食总产量的影响。结果显示:高标准农田建设政策对粮食增产有显著的积极效应,但影响效应具有滞后性,直到政策规范实施后的2013年才出现。作用机制分析表明:政策实施的粮食增产效应是在未挤占经济作物播种面积的条件下,通过激励农户提升粮食复种指数,扩大粮食播种面积而实现的。进一步研究发现,耕地适度规模经营有助于发挥政策的粮食增产效应,且在农地流转率、劳动力转移率及机械化水平更高的地区有更好的政策表现。
英文摘要:
      Based on the quasi-experimental conditions for the subregional promotion of China's high-standard farmland construction policy, using the balanced panel data of 30 provinces from 2006 to 2017, the impact of the high-standard farmland construction policy on the total grain output was empirically tested by using the Difference-in-Differences Model. The results show that the high standard farmland construction policy has a significant positive effect on grain production, but the impact effect is lagging, and it does not appear until 2013 after the implementation of the policy norms. The analysis of the mechanism of action shows that the effect of the implementation of the policy on grain yield increase is realized by encouraging farmers to improve the grain multiple cropping index and expand the grain sown area under the condition that the sown area of cash crops is not crowded. Further research found that appropriate scale management of cultivated land was helpful to give play to the grain production effect of the policy, and had better policy performance in areas with higher agricultural land transfer rate, labor transfer rate and mechanization level.
