"市场定价+生产者补贴"的玉米收储制度改革是推进重要农产品价格形成机制与政府补贴脱钩改革的创新探索,引起了玉米生产要素配置调整和配置效率变化.基于2005-2020年20个玉米省级产区面板数据,采用双重差分模型探究了玉米收储制度的实施及其改革影响玉米生产要素配置效率的净效应.结果表明:实施收储制度显著降低了玉米生产的要素配置效率,收储制度的价补分离改革则削弱了其制度本身对于玉米要素配置效率的抑制作用,传导机制是通过影响玉米现金收益和种植规模作用于要素配置效率.尽管玉米生产者补贴依然造成配置效率损失,但这一市场化改革举措仍可以视作优化要素配置、改善要素配置效率的重要举措.基于此,提出持续巩固农产品收储制度及价格形成机制改革成果,逐步以市场化综合型生产支持措施替代扭曲性补贴措施等建议.
How does the temporary state collection and storage system reform affect efficiency of maize production factor allocation in China?
The reform of maize temporary state collection and storage system is an innovative exploration to promote the decoupling of agricultural production price formation mechanism reform and government payments,which causes the adjustment of factor allocation and the change of factor allocation efficiency in maize production.Based on panel data of 20 provincial producing areas of maize from 2005 to 2020,this paper uses the double-difference model to explore the net effect of the implementation of temporary state collection and storage system and its reform on the factor allocation efficiency of maize.The result are as follows:The implementation of temporary state collection and storage system significantly reduces the factor allocation efficiency of maize production,while its reform weakens the negative effect.The transmission mechanism is that the policy implementation or its reform affects the factor allocation efficiency by influencing the income and planting scale of maize.This market-oriented reform can be regarded as an important measure to optimize the factors allocation and improve the factor allocation efficiency.Although the subsidies paid to the maize growers have a distorting effect and cause the loss of factor allocative efficiency,this market-oriented reform measure can still be seen as an important measure to optimize factor allocation and improve factor allocation efficiency.So,the reform of temporary state collection and storage system and price formation mechanism should be strengthened constantly,and the distorted subsidy measures should be gradually replaced by market-oriented comprehensive production support measures,to enhance the capacity of sustainable development of grain production.
