基于H-P滤波及回归模型的江苏省粮食供需平衡分析
利用EViews6.0计量学分析软件,对江苏省过去21年的粮食供给和需求变动情况进行了统计分析,应用H-P滤波方法建立了粮食需求与供给的预测模型,结果显示,模型拟合精度非常高;对未来5年粮食供需的结果表明,粮食供需基本平衡,但是,随着人们粮食需求的不断增加,粮食安全将面临挑战,因此,提出了相应的对策建议以缓解粮食供需矛盾。...

Bibliography: | 36-1124/S LIU Xiao - chuan , ZHANG Pei - qi, ZHU Li - qun, BIAN Xin - min ( 1. College of Resources and Environmental Sciences, Nanjing Agricultural University, Nanjing 210095, China; 2. College of Agronomy, Nanjing Agricultural University, Nanjing 210095, China) By using metrological analysis software EViews6.0, the author analyzed the grain supply - demand balance during the past 21 years in Jiangsu province, and established the grain supply and demand prediction model based on the application of H- P fil- ter method. The results showed that the simulative precision of the established model was very high. The predictive results of the grain supply - demand in the future 5 years indicated that the grain supply and demand was basically balanced; however, along with the con- tinuous increase in grain demand by the people, the food security would face a huge challenge. Therefore, the author put forward the relevant advices for alleviating the contradiction between grain supply and demand. Grain supply - demand bal |
