基于整体网分析法的中国服务贸易国际竞争力分析

文章采用联合国贸发会议统计数据库服务贸易数据,基于服务贸易进出口关系,构建六个服务贸易关联网络,选取整体网分析法中的点度中心性指标、中间中心性指标和基于CONCOR算法的核心-边缘结构性指标,对中国服务贸易在2008年金融危机前后10年间的国际竞争力状况及其变化进行了研究。分析显示:金融危机后全球各经济体间的服务贸易往来愈加密切;中国在全球服务贸易网络中的竞争力总体偏低但地位有所上升,且进口地位优于出口地位;金融危机后中国在国际服务贸易网络中的权力地位快速提升,渐由半边缘地带转向核心地带,对其他经济体的影响力增强,尤其是东亚和东南亚等周边区域。总之,中国在全球服务贸易网络中的竞争力正在由弱转强。

An Analysis of International Competitiveness of China’s Service Trade Based on Whole Network Analysis

Based on the service trade data from United Nations Conference on Trade and Development( UNCTAD) in 2007, 2009 and 2016 as well as the import and export relationships of service trade, this paper constructs six service trade related networks and selects degree centrality index, betweenness centrality index and core-periphery structure index which is on the basis of CONCOR algorithm to study the international competitiveness of China’s service trade in the 10 years before and after the 2008 subprime crisis. The research shows that after the financial crisis, service trade among the world’s economies becomes increasingly close. Besides, China’s competitiveness in the global service trade network is generally weak, while the position of the region to which China belongs rises, and it has a stronger influence on import than export. Furthermore, after the financial crisis, China’s power in the international service trade network increases rapidly and its position gradually changes from the semi-marginal zone to the core zone, which enhances its influence on other economies, especially in the surrounding regions such as East Asia and Southeast Asia. In short, China is becoming more and more competitive in the global service trade network.
