中文摘要:采用ARMA 模型,对中国农产品生产价格指数(1979-2010)时间序列进行了建模分析.结果表明,ARMA(5,1)模型是平稳的且是可逆的.对2011-2013的中国农产品生产价格指数GPIFP进行了短期预测.预测结果分别是112,102和108.采用ARMA模型进行农产品生产价格指数的分析与预测,能较好地反映其动态变化,对促进我国农产品价格市场和谐发展具有重要的参考价值.

Analysis and Early-warning on GPIFP of China Based on ARMA Model
Abstract:This article mainly discussed how to construct the model of ARMA for the economic time series of GPIFP of China (1979-2010) and how to forecast GPIFP value in short-term.The empirical analysis shows that the ARMA(5,1) model was stable and reversible. The ARMA model was used to predict the GPIFP in the next three years (2011-2013), which shows the prediction results are 112, 102, 106 respectively. At the sane time the ARMA model can reflect effectively the dynamic change in GPIFP. It has important reference value to the harmonious development of the agricultural product price market in China.
