【摘要】：文章应用平滑迁移误差修正模型分析了猪肉收储政策对生猪产销价格间非对称传导机制的影响,进而评价猪肉收储政策的实施效果。结论如下:从长期来看,猪肉收储政策的实施降低了生猪产业链纵向整合水平;从短期来看,猪肉收储政策提高了生猪产销价格间的传导速度以及生猪价格正常波动时生猪产销价格系统恢复长期均衡关系的调整速度,但是也增加了生猪产销价格间非对称传导发生的概率,破坏了生猪产销价格系统的自我修复能力。从生猪产销价格间非对称传导视角来看,猪肉收储政策的实施效果并不理想。
[Abstract]:This paper analyzes the effect of pork storage policy on asymmetric conduction mechanism between production and marketing prices of live pigs by using smoothing migration error correction model, and then evaluates the implementation effect of pork storage policy. The conclusion is as follows: in the long run. The implementation of pork storage policy reduces the vertical integration level of pig industry chain; In the short term, the policy of pork storage improves the conduction speed between the production and marketing prices of live pigs and the adjustment speed of restoring the long-term equilibrium relationship between the production and marketing price system of live pigs when the price of live pigs fluctuates normally. But it also increases the probability of asymmetric conduction between the production and marketing prices of live pigs, and destroys the self-repair ability of the production and marketing price system of live pigs. From the perspective of asymmetric transmission between production and marketing prices of live pigs. The effect of pork storage policy is not ideal.

【正文快照】： 0引言由于生猪产销价格水平的稳定对促进生猪产业的健康发展和实现物价稳定的宏观调控目标具有重大现实意义。因此,我国从2009年开始实施猪肉收储政策,以期稳定生猪产销价格波动水平,那么猪肉收储政策实施的效果如何?如何来评价该政策的优劣?与以往研究不同的是,本文将基于猪
