水产饲料价格波动对养殖成本的影响研究
Research on impact of fluctuations in aquatic feed prices on breeding costs
摘要
Abstract
Stabilizing the price of aquatic feed is an important means to improve the self-sufficiency level of aquatic products,a powerful measure to ensure the development of fishery economy,and the core of promoting high-quality development of aquaculture industry.Based on monthly data from January 2015 to January 2023,this study uses VAR model,impulse response function,and variance decomposition method to explore the impact of aquatic feed price fluctuations on aquaculture costs.The results showed that there is a cointegration relationship between the fluctuation of aquatic feed prices and aquaculture costs,that is,the fluctuation of aquatic feed prices is an important factor affecting aquaculture costs,and the linkage relationship between the two exists for a long time.The response period for the impact of aquatic feed prices on aquaculture costs is about two years,and in the second year,the contribution rate of aquatic feed prices to aquaculture costs is about 6.884 9%.The study indicates that the high contribution of aquatic feed prices to aquaculture costs proves that fluctuations in aquatic feed prices are an important factor affecting aquaculture costs.关键词
