摘要
近期,一些学者开始运用网络传播方法研究价格波动关联效应.但在构建价格波动关联网络过程中网络是对称的,与实际价格波动关联情况有较大差距.文章为克服网络对称的问题,将原包含240种消费品的对称价格波动关联网络划分为30个部门子网络(局域网),然后运用上述部门间投入产出消耗系数把30个子网络连接起来形成新的价格波动关联效应网络.该方法可有效地克服研究价格波动关联效应遇到的网络对称难题,为探索价格波动网络传播机制提供了新的思路和方法.
Recently, some scholars began to study the effects of price volatility associated with the use of network communication methods.But the constructed price volatility network often encountered symmetric problem, Correspondingly, there was a wide gap on price volatility associated effect between the actual and the constructed network. In order to overcome the problem of network symmetry, the paper splitted the original price volatility associated symmetrical network into 30 sub-network, then inked the 30 sub-networks to form a new network by using input-output relations. This new method can effectively overcome network symmetrical problem, and Provide new ideas and methods of the formation mechanism on network.
