价格波动网络传播模型：研究价格波动关联效应的新方法

摘要

学者们利用经济计量模型、一般均衡模型、投入产出价格影响模型或者它们相结合的方法研究商品价格波动对其它商品的影响。但由于运用上述模型，特别是投入产出价格影响模型，来研究价格波动关联效应存在拆并投入产出表困难，导致研究大样本商品之间的价格波动关联影响非常困难。引入网络传播视角，将价格波动关联效应视为网络节点之间服从某种规律的传播行为，建立了价格波动网络传播模型并对广东价格波动关联效应进行了研究。研究表明：利用网络传播模型研究价格波动关联效应方便有效，模型可为研究消费品价格波动情况提供新的视角和方法。%In recent years , the scholars have used econometric model , general equilibrium model , input-output price influence model or their combination models to study price volatility associated effect .How-ever , it is very difficult in demolishing and reorganizing input-output table to study price volatility associ-ated effect based on the price influence model .To overcome the above difficulty , price volatility network propagation model is established by introducing network communication perspective , i.e.price volatility correlation effects are regarded as network nodes propagation behavior .The study shows that the price volatility network propagation model is more convenient and effective on studying price volatility associat -ed effect .This new method provides a new perspective for the study of price volatility associated effect .
