摘要:

为了保障粮食安全和农户种植收益,实现区域种植结构合理布局,本研究基于农产品收购政策研究视角,运用DID模型,对黑龙江省2001—2018年种植结构变化与政策驱动的关系进行实证分析。结果表明,最低收购价格政策、临时收储价格政策、“价补分离”政策对水稻、玉米种植面积和收益有显著正向影响;目标价格政策对大豆种植面积有显著负向影响,临时收储价格政策、“价补分离”政策影响效果不明显,且“价补分离”政策对大豆收益产生显著正向影响,但临时收储价格政策、目标价格政策影响效果较小;农作物滞后一期收益对除玉米“价补分离”政策时期外的农户种植决策产生正向影响。分析种植结构变化与政策驱动关系,对重新审视农业政策、制定和完善未来粮食安全保障措施等有重要意义。

Abstract:

To ensure food security and farmers’ income from planting, and to realize the rational distribution of regional planting structure, difference in difference method (DID) was used to analyze the relationship between the change of planting structure and policy drive in Heilongjiang Province with the statistical data from 2001 to 2018, based on the research perspective of agricultural product acquisition policy. The results showed that the minimum purchase price policy, the temporary storage price policy and the ‘price-subsidy separation’ policy had a significantly positive effect on the planting area of rice and corn, and promote the increase of planting income at the same time. The effect of temporary storage price policy and ‘price-subsidy separation’ policy on soybean planting area was not obvious, while the target price policy had a significantly negative effect on soybean planting area. However, the ‘price-subsidy separation’ policy had a significantly positive effect on soybean income, but the effect of temporary storage price policy and target price policy was relatively small. The pre-crop income had a positive effect on the farmers’ planting decision except for the policy period of corn ‘price-subsidy separation’ policy. Therefore, the analysis of the relationship between planting structure change and policy-driven is significant to re-examine agricultural policies, as well as further draft and revise the future food security measures.

Key words: food security, DID, planting structure, policy-driven, policy effect, Heilongjiang Province
