Research On The Competitiveness And Influencing Factors Of Knowledge-intensive Business Service Trade In China,USA And Japan

In the context of rapid economic development,the proportion of service trade in the international trade is increasing gradually and it becomes increasingly important,especially in the knowledge-intensive business service trade.With the progress of technology and the adjustment of international industrial structure,the rapid growth of the knowledge-intensive business service becomes the typical feature and trend of contemporary world economic development.The competitive advantage of knowledge-intensive business service trade has become the key factor in the high-end international competition in a country or region.As a competitive country in economy and trade,knowledge-intensive business service trade has become an important part of trade between two countries.Therefore,the comparative analysis of the competitiveness of service trade between two countries and the comprehensive study of the influencing factors help to promote further economic cooperation between China and the United States as well as Japan.Besides,this is of great guiding significance to further optimize the structure of China’s service trade and improve its competitiveness.Based on the theory of competitive advantage and Diamond Model,four factors affecting the competitiveness of service trade are chosen,namely,human capital,R&D investment,development of service industry and goods export to build the measurement model of service trade competitiveness.Starting from four dimensions,that is,competitiveness index of export scale,competitiveness index of export structure,competitiveness index of export effectiveness and competitiveness index of export efficiency,this article will set up an evaluation system and calculate the proportion of each dimension by using principal component analysis.Through proper allocation of proportion,the comprehensive competitive advantage index will be established.By analyzing the competitive advantage and influencing factors of knowledge-intensive business servicetrade of China,the United States and Japan comprehensively,countermeasures will be extracted to improve the development of knowledge-intensive business service in China.
