摘要:

目的 为了解收储制度改革背景下农户玉米种植调整行为，从而对优化农业种植结构、保障玉米稳定供给的科学决策提供参考。方法 文章基于辽宁、吉林、黑龙江、内蒙古423个农户调查数据，通过建立有序多分类Logistic回归模型，将玉米种植优势产区与非优势产区样本农户的玉米种植调整行为进行对比分析。结果 研究发现不同产区农户玉米种植调整行为影响因素存在差异。在优势产区，农户新品种采用意愿、家庭劳动力数量、其他作物面积、玉米收入占比、生产者补贴标准满意度对玉米种植调整行为影响显著。在非优势产区，农户上一年种植面积、玉米收入占比、合作组织对玉米种植调整行为影响显著。结论 进一步完善生产者补贴机制，适当提高优势产区玉米补贴标准；加强玉米良种研发，实施“藏粮于技”战略；加强对农业经营主体的培育扶持，有效推动种植结构调整。

Abstract:

This paper is intended to understand corn farmers' planting behavior adjustments in the context of reforms in system of purchase and storage, so as to provide reference for the scientific decision-making in optimizing corn planting structure and ensuring the stable supply of corn. Based on a survey data of 423 farmers from Liaoning province, Jilin province, Heilongjiang province, and Inner Mongolia autonomous region, this paper established an ordered multi-class logistic regression model and compared and analyzed the planting behavior adjustments of corn farmers from advantageous areas and disadvantageous areas.The results showed that for corn farmers from different production areas, there were different factors to impact their planting behavior adjustments. Specifically, in advantageous areas, factors which had significant influence on planting behavior adjustments included farmers' willingness to plant new varieties of corn, the number of labor force in each family, the planting area of crops other than corn, the share of income from corn in total income, and the satisfaction with the standard of producer subsidies. In disadvantageous areas, the significant factors included farmers' planting area in the last year, the share of income from corn in total income, and the types of cooperative organization.Therefore, we should improve the producer subsidy mechanism, raise the corn subsidy standard properly in advantageous areas, strengthen the development of corn varieties of high quality, implement the food crop production strategy based on technological application, reinforce the cultivation and support for agricultural businesses, so as to effectively promote the adjustment of planting structure.
