摘要
大豆是中国重要的粮食作物,但是对外依存度很高,振兴国产大豆,保障粮食安全成为迫切之需。基于中国2013—2020年大豆主产省份的面板数据,利用双重差分法实证分析国家大豆生产者补贴政策对大豆产量的影响。实证分析表明:生产者补贴政策实施对大豆产量产生正向显著影响,大豆总产量的增加主要来源于生产者补贴政策实施带来的大豆种植面积的扩大而非单产的提高。建议扩大政策补贴实施范围,提高大豆单产水平,提升大豆竞争力。
Soybean is an important food crop in China,but its dependence on import and export is very high.Therefore,increasing domestic soybean yield has become an urgent need for ensuring food security.Based on 2013-2020 panel data from major soybean-producing provinces,and using double difference method,this paper makes an empirical analysis of the impact of soy producer subsidies on soybean yield.The result shows that the implementation of producer subsidies had a significant positive impact on soybean yield.It is found that the increase in total soybean production mainly came from the expansion of soybean acreage supported by the implementation of producer subsidies policy,rather than the increase in per unit area yield.In light of this,it is recommended to expand the scope of policy subsidies,increase the per unit area production yield of soybean,and enhance the competitiveness of soybean.
