[目的]揭示我国鸡饲料市场价格的波动特征和规律。[方法]选用HP滤波、ARCH类模型,运用2001—2016年我国蛋鸡和肉鸡饲料月度市场价格统计数据,分析我国蛋鸡和肉鸡配合饲料市场价格的波动特征和规律。[结果](1)肉鸡饲料价格整体高于蛋鸡饲料价格,但两种饲料价格波动走势相似,总体波动呈“W”型,都经历4个阶段,大致分别呈“V”“U”“/”和倒“U”型,两种饲料价格波动率序列均具有明显的“右偏、尖峰、厚尾”特征,且都不服从正态分布; (2)两种饲料价格均存在显著的ARCH效应,且两者价格波动率具有明显的集聚效应,持续性特征比较明显,价格冲击对两者价格波动的影响持续时间长; 两种饲料市场均不存在“高风险高回报”特征; 两者价格波动具有显著的非对称性,且价格上涨信息引发的波动比价格下跌信息引发的波动要大。[结论]我国蛋鸡和肉鸡配合饲料市场价格的波动特征和规律相似且一致。 |

Abstract: |
The purpose of this paper is to reveal the fluctuation characteristics and rules of the market price of chicken feed in China. Based on the monthly market price statistics of domestic egg chicken and broilers feed from 2001 to 2016, it mainly used HP filtering and ARCH model to analyze the formula feed market price fluctuation characteristics and rules of egg chicken and broilers. The results showed that (1)Broilers feed prices was higher than egg chicken feed prices, but the price fluctuation trend of them was similar and the overall fluctuation presented "W" type, and had roughly experienced four stages, which were roughly "V", "U", "/", "U" type, both feed price volatility series had obvious "right shift, peak, thick tail" characteristics, and neither obey normal distribution. (2) Both feed prices fluctuation existed the ARCH effect, and the price volatility of them had obvious accumulative effect and sustainability features of them was obvious, and the impact of price shock to price fluctuations was long, and both feed markets didn′t have the features of "high risk, high return and low risk and low return", and both price fluctuations had significant asymmetry, and the price fluctuations were caused by price increase information was larger than that caused by price drop information. The conclusions is that fluctuation characteristics and rules of egg chicken and broilers formula feed market prices are similar and consistent. |
