摘要
本文对影响吉林省生猪规模生产效益主要因素进行协整分析,通过协整检验分析各个因素与生猪规模生产成本收益率是否存在长期稳定均衡关系,并且运用Granger检验分析各个变量之间的因果关系。结果表明吉林省生猪规模养殖生产效益受每50千克主产品出售价格、精饲料费、仔畜费等三个因素与生猪规模生产效益存在因果关系,并且出售价格对生猪规模生产效益影响大于精饲料费、仔畜费的影响程度。因此,在调整生猪主产品出售价格时应该关注生猪生产过程中的饲料费和仔畜费,为提高生猪规模生产效益,增加农民收入,促进吉林省生猪规模生产提供参考依据。
This article on the impact of major factors of hog scale production profit, through cointegration analysis on long-term stable equilibrium relationship of the various factors and hog scale production costs yields, and using Granger test to analysis on causality of variables. The results showed hog scale production profit is mainly affected by the sale price of per 50kg main product, concentrate feed costs, newborn animal fees, there is a causal relationship between the variables and hog scale production profit, the impact of sale price to the hog scale production profit more than concentrate feed costs and fees newborn animal. Therefore, when adjustment sold price of the hog main product process should focus on the newborn animal fees and feed costs, to improving hog scale production profit, increase farmers income and provide references to promote hog scale production in Jilin Province.
