过程与公式	描述与说明
$W j = (A i - N i) (X i - V i) (A i + N i - 2 V i) X i + A i V i + N i V i - 2 A i N i$	将政治、经济、社会3个维度17个指标标准化处理，式中：A_i、N_i、V_i分别代表指标X_i的最大值、最小值与均值；W_i代表标准化后的指标值。其中正向指标标准化后的数值为W_i；负向指标标准化后的数值为-W_i。
$W = ∑ i ≠ j i, j (W i + 1) (W j + 1) 2 n (n - 1$	以标准化的指标W_i计算3个维度的风险综合指数，式中：W_i、W_j为第i、j个分项指标（i、j = 1, 2, 3, …, n，i ≠ j）n为指标个数；W为综合指数值，其介于0~1之间，取值越大代表风险越高。
$W C a b = W P a b × α + W E a b × β + W S a b × γ$	式中： $W C a b$ 、 $W P a b$ 、 $W E a b$ 、 $W S a b$ 分别表示a年份b国家的综合地缘风险、政治风险、经济风险、社会风险指数；α、β、γ为权重取值分别为0.4、0.3、0.3，为作者根据梳理的各类资料数据主观赋权得到。
