摘要: |
本文基于2014~2019年我国8个省(区)960户农户的面板数据,采用双重差分法(DID)和倾向得分匹配—双重差分法(PSM-DID)研究了玉米“价补分离”政策对农户生产行为的影响。研究结果表明:从平均特征维度来看,玉米“价补分离”政策影响了农户的生产行为,减少了玉米生产过程中土地、劳动和物质要素的投入,其中对农户的土地投入行为影响最大;从动态特征维度来看,玉米“价补分离”政策实施之初,对农户生产行为影响较大,但是后续效应减弱。特别是政策实施的第三年,产生了政策效果与政策目标偏离现象;从空间特征维度来看,玉米“价补分离”政策对农户生产行为的影响呈现出玉米非优势产区大于玉米优势产区的特点。针对上述结论,进一步说明了其政策启示。 |

Abstract: |
Based on the panel data of 960 households in 8 provinces(regions)of China from 2014 to 2019,this paper studies the impact of the price-subsidy separation policy of maize on farmers" production behavior by using the double difference method (DID) and propensity score matching-double difference method (PSM-DID).The results show that,from the average characteristic dimension,the policy of separation of price and subsidy has an impact on farmers" production behavior,reducing the planting area of maize and the input of labor and material factors in the process of maize production,and farmers"land investment behavior is the most affected;From the perspective of dynamic characteristics,at the beginning of the implementation of the policy of separation of price and subsidy,the impact on farmers" production behavior is greater,but the follow-up effect is weakened.Especially in the third year of the implementation of the policy,there is a deviation between the policy effect and the policy goal;From the perspective of spatial characteristics,the impact of the policy of separation of price and subsidy on farmers" production behavior shows that the impact of non-dominant maize producing areas is greater than that of dominant maize producing areas. In response to the above conclusions,this paper further illustrates its policy implications. |
