Characteristics of spatial correlation network for corn markets
指标 | 公式 | 含义 | |
---|---|---|---|
整体网络 | 网络密度 | | 反映玉米市场空间关联网络的紧密程度,网络密度越大,省际玉米市场之间的联系就越紧密。 |
网络关联度 | | 反映玉米市场空间关联网络的稳健性和脆弱性,关联度越高,网络越稳定。 | |
网络等级度 | | 反映玉米市场空间关联网络的等级结构,等级越高,越多省份在玉米市场关联网络中处于从属和边缘地位。 | |
网络效率 | | 反映玉米市场空间关联网络的效率,效率越低,玉米市场空间关联网络越稳定。 | |
个体网络 | 度数中心度 | | 反映一个地区在玉米市场空间关联网络中的影响力,中心度越大,市场影响力越大。 |
中间中心度 | | 反映一个地区在玉米空间关联网络中的“中介”或“桥梁”作用。 | |
接近中心度 | |
