摘要
玉米收储制度在2016年正式开始了新一轮的改革,其中包括取消玉米临时收储政策和建立生产者补贴制度两种措施。本文先将我国19个生产玉米的省(区、市)分成两个样本组——东北三省占内蒙古自治区和其余15个省(区、市),然后用随机前沿法对两个样本组2004-2018年的玉米生产数据进行分析,并对比了临时收储政策实施和新一轮收储制度改革前后两组玉米生产技术效率的变化。研究结果表明,玉米生产技术效率会在临时收储政策实施后的第二年得到显著提高。而新一轮收储制度改革会促使玉米生产技术效率在改革后的第一年就出现上升趋势,但增速较缓,这可能是与临储政策的取消和生产者补贴两种措施共同作用有关。
The corn purchasing and storage system officially began a new round of reform in 2016,including the cancellation of the temporary corn purchasing and storage policy and the establishment of producer subsidy system.This article will first divide 19 corn production provinces in China into two sample group—three northeast provinces and one region with the rest of the 15 provinces,then by using the stochastic frontier method for two sample group of 2004—2018 corn production data is analyzed,and compared the reserve policy implementation and a new round of purchasing two groups before and after the reform of the system of corn production technical efficiency change.The results showed that the technical efficiency of corn production would be significantly improved in the second year after the implementation of the temporary purchase and storage policy.The new round of the reform of the purchasing and storage system will promote the technical efficiency of corn production to rise in the first year after the reform,but the growth rate is relatively slow,which may be related to the cancellation of the temporary storage policy and producer subsidies.
