摘要
大豆补贴政策改革的经验与效果对于探索稻谷、小麦等农作物补贴政策改革方向具有重要的借鉴价值。为此,本文基于中国大豆主产区地级市层面的面板数据,利用双重差分模型详细考察了2017年推出的大豆生产者补贴政策对大豆生产的影响。研究结果显示,生产者补贴政策的实施达到了扩大大豆播种面积的政策目标,但同时也造成了生产要素投入的下降。从改革的时间过程来看,改革的第一年,大豆生产变动更多反映的是取消大豆目标价格补贴带来的影响而非大豆生产者补贴的实际效果,因此出现了大豆播种面积、面积占比和单位面积投入均减少的现象;但是第二年和第三年生产者补贴的扩种效应逐渐凸显,大豆播种面积呈逐年递增态势。区域异质性分析显示,生产者补贴对不同省份和积温带大豆生产的影响各异,黑龙江省和内蒙古自治区东部四盟市对生产者补贴更为敏感,而且补贴对这两个省区的第二、第三和第五积温带种植大豆的激励效果最为显著。
The experience and effects of the soybean subsidy policy reform have important reference value for exploring the direction of the subsidy policy reform for rice,wheat and other crops.To this end,this article uses a difference-in-differences model to investigate the impact of the soybean producer subsidy policy launched in 2017 on soybean production,based on the panel data of prefecture-level cities in China’s main soybean producing areas.The results of the study show that the implementation of producer subsidy policy has achieved the policy goal of expanding soybean planting area,but at the same time it has also caused a decline in the input of production factors.From the perspective of the time course of the reform,in the first year of the reform,changes in soybean production have more reflected the impact of the cancellation of the soybean target price subsidy compared with the actual effect of the soybean producer subsidy.Therefore,soybean planting area,the area proportion and input per unit area of soybean have all decreased.However,the effect of producer subsidies on seed expansion in the second and third years has gradually become prominent,and the sown area of soybeans has been increasing year by year.The analysis of regional heterogeneity shows that producer subsidies have different effects on soybean production in different provinces and accumulated temperature zones.Heilongjiang Province and four league cities in the east of Inner Mongolia are more sensitive to producer subsidies.Moreover,the incentive effect of producer subsidies on soybean production in the second,third and fifth accumulated temperature zones ofthese two provinces is most significant.
