全球价值链视角下大湄公河次区域服务业竞争力研究

Research on the Competitiveness of Service Industry in the Greater Mekong Sub-region from the Perspective of Global Value Chain

利用亚洲开发银行编制的投入产出表ADB-MIRO(2018),基于KPWW贸易增加值核算方法,对GMS服务业的全球价值链参与程度、地位指数和基于增加值的显示性比较优势指数进行测算,引入增加值等全球价值链相关变量,实证分析了GMS服务贸易竞争力的影响因素。研究结果表明,中国服务业GVC参与程度较弱、地位指数处于全球价值链上游、服务业整体及细分产业竞争优势不明显,GMS整体及各国在全球价值链中基于前向分解的服务业部门的增加值出口贸易(lnvax_f)是NRCA指数的重要影响因素,且对不同国家影响程度各不相同。

Using the input-output table ADB-MIRO(2018)prepared by Asian Development Bank,and based on the KPWW trade value-added accounting method,this paper calculates the global value chain participation degree,position index and value-added based demonstrative comparative advantage index of GMS service industry,introduces value-added and other global value chain related variables,and empirically analyzes the influencing factors of GMS service trade competitiveness.The results show the weak GVC participation of China’s service industry,the upstream position of the status index in the global value chain,and the implicitness of its competitive advantage in the whole service industry and the segment industry.The value-added export trade()of the whole GMS and other countries in the global value chain based on the forward decomposition of the service sector is an important influencing factor of the NRCA index,and its impact on different countries is different.
