国际产业价值链视角下的世界平衡性网络演化

伴随经济全球化和区域经济一体化不断加深,国际产业价值链的分工和转移对世界经济平衡性演化结构的重塑产生重要作用。基于WIOD数据,运用社会网络分析法构建测度指标体系对国际经济网络的特征进行探索,引入熵值指标和借鉴最优分割理论对国际经济网络演化路径进行分析,研究结果表明：世界经济网络联系呈现不断增强的趋势,以2001年作为转折点,世界经济空间网络由南北两个极端的格局逐渐向有序、平衡的发展阶段迈进,其中,中国对世界网络平衡性演化的影响在逐步加强。

With the deepening of economic globalization and regional economic integration, the division of labor and transfer of international industrial value chains play an important role in the reshaping of the evolutionary structure of the world economy. Based on the WIOD data, the social network analysis method is used to construct the measurement index system to explore the characteristics of the international economic network. The entropy index and the optimal segmentation theory are introduced to analyze the evolution path of the international economic network. The results show that the world economic network links are presented. With the trend of increasing, with 2001 as a turning point, the world economic space network has gradually moved from an extreme pattern of north and south to an orderly and balanced development stage. Among them, China"s influence on the evolution of world network balance is gradually strengthening.
