【摘要】：目前諸多社團劃分算法往往面向一般意義的復(fù)雜網(wǎng)絡(luò),針對具體問題應(yīng)用時需要篩選和改進。為了提高國際貿(mào)易網(wǎng)絡(luò)社團劃分的準確性與合理性,考慮現(xiàn)實國際貿(mào)易主體平等、聯(lián)系普遍、流量懸殊、市場依賴、貿(mào)易組織重疊、社團相對穩(wěn)定和貿(mào)易波動等特性對社團劃分的影響,提出一種引入貿(mào)易依賴度權(quán)重的派系過濾算法。將該算法應(yīng)用于海上絲綢之路貿(mào)易社團劃分,通過檢驗算法結(jié)果的社團結(jié)構(gòu)可辨識性、模塊度Q值、現(xiàn)實契合度和可解釋性,驗證了該算法的有效性。
[Abstract]:At present, many community partition algorithms are often oriented to the general meaning of complex networks, and need to be screened and improved in the application of specific problems. In order to improve the accuracy and rationality of the division of international trade network associations, we should consider the equality of international trade subjects, the universality of links, the disparity of flows, the dependence of the market, and the overlap of trade organizations. Based on the influence of the characteristics of relative stability and trade fluctuation on the division of associations, a factional filtering algorithm based on trade dependency weight is proposed. The algorithm is applied to the maritime Silk Road trade community division. The validity of the algorithm is verified by verifying the identifiability of the association structure, the Q value of modularity, the practical agreement and the interpretability of the algorithm.
