全球价值链视角下中国服务业竞争力的再评估

Reevaluation of China's Service Industry Competitiveness in the Global Value Chain

基于WWZ(2014)分解模型和世界投入产出数据库(WIOD)的数据,从国外及国内增加值两个角度分别采用相对出口贡献指数和三种显示性比较优势指数对中国服务业及其细分行业在全球价值链中的竞争力进行再评估。研究发现:各区域在中国服务业出口中的相对贡献程度指数值总体上大于1;除金融业外,各区域对中国其他各细分行业和整体服务业的相对出口贡献指数均值都大于1;在研究期间,中国服务业的三种显示性比较优势指数都呈现上升趋势,表明中国服务业的国际竞争力在加强。但TRCA和NRCA都明显高估了中国服务业的国际竞争力,并且三种显示性比较优势指数之间的差值随着时间的移动越来越大。

Based on the decomposition model of WWZ （2014） and the data from the world input -output database （WIOD）, this paper measures the competitiveness of China＇s service industry and its sub - industries in the global value chain from both the outer and inner China perspectives. Furthermore, it compares this new evaluation with the traditional ＂total value＂. It finds out the following results：The relative contribution of each region to China＇s service sector exports is greater than 1 ;There are significant differences in the relative exports contribution index of different regions to china. Besides the financial industry, the other sub - industries of the service industry and the overall service industry＇s relative exports contribu- tion index is greater than 1 ;During the research period, the three types of comparative advantage index of China＇s service industry show a rising trend, which indicates that the international competitiveness of China＇s service industry is strengthened. However, TRCA and NRCA have signifi- cantly overestimated the international competitiveness of China＇s service industry, and the differences among the three types of comparative advan- tage index are larger and larger within the time.
