摘要
本文基于动态面板数据模型,采用Blundell和Bond(1998)提出的系统广义矩估计及Windmeijer(2005)的两步估计标准差的小样本纠正方法,对我国农产品价格波动对通货膨胀的影响进行研究。结果表明:农产品价格波动对通货膨胀的影响呈显著下降趋势,通货膨胀预期对实际通货膨胀的形成作用逐步加强。
Based on dynamic panel data model,the article applies the system GMM estimates by Blundell and Bond (1998) and finite sample correction for the variance of linear efficient two-step GMM estimators by Windmeijer (2005) to study the impact of price fluctuation of agricultural products on inflation.The results show that the impact of price fluctuation of agricultural products on inflation presents significant downward trend,while the impact of inflation expectations on the actual inflation' formation is getting strong.
