| With the continuous innovation and comprehensive application of the new generation of information and communication technology(ICT),the global digital trade develops rapidly and becomes a new driving force to promote economic growth.At the same time,The deepening division of global value chain,the changes in the global competitive environment and market demand make it urgent to improve the quality and efficiency of the manufacturing industry.Various countries have formulated relevant industrial policies to promote manufacturing servitization and building competitive advantage.Digital trade can effectively reduce costs,improve efficiency,optimize allocation of global resources and supply chain management,promote the development of service trade,which has a profound impact on the global division and the construction of competitive advantage.With the rapid development of digital trade,the manufacturing industries of various countries are also undergoing the transformation and upgrading of digitalization,servitization and intelligence.From this point of view,the following thoughts arise:Is digital trade affect the servitization and international competitiveness of manufacturing industry?The discussion of this issue has certain theoretical and practical significance for the development of digital trade and the formulation of relevant policies,the path selection of manufacturing servitization and international competitiveness promotion.The current research on digital trade focuses on the development process and characteristics,trade rules and governance,and analysis of typical enterprise.There is a lack of literature exploring the economic effects of digital trade from theoretical and empirical levels.At the same time,the existing researches on the factors influencing of manufacturing servitization and international competitiveness have ignored the background of the rapid development of global digital trade.Based on this,this dissertation studies the impact of the development of digital trade on the manufacturing servitization and international competitiveness,and uses the mediation effect model to explore the logical relationship between the three.This dissertation systematically analyzes the influence of digital trade on trade cost,resource allocation efficiency,service trade development and consumption upgrading,and then the influence on manufacturing servitization and international competitiveness.In previous studies,questionnaire surveys,cross-section data or typical enterprise data were used to evaluate digital trade.This dissertation constructs an evaluation system to systematically and comprehensively evaluate the development of digital trade.In addition,from the perspective of global value chain export competitiveness,value-added RCA index,value-added export technical sophistication index and position of global value chain are choosed as indicators to measure the international competitiveness of manufacturing industry,and make comparative analysis among countries and industries based on different dimensions.Then,this dissertation empirically tests the impact of digital trade on manufacturing servitization and international competitiveness of manufacturing industry;and uses mediation effect model examine the logical relationship between the three.Finally,some suggestions are given.This dissertation consists of nine chapters.Chapter 1 is the introduction,which briefly introduces the research background,purpose and significance,research ideas,methods and innovation points of this dissertation.Chapter 2 is a literature review.Chapter 3 is the definition of connotation,logical framework and theoretical analysis.Chapter 4 measures digital trade,manufacturing servitization and international competitiveness of manufacturing industry from different perspectives and makes international comparative analysis.Chapter 5 empirically studies the impact of digital trade on manufacturing servitization,and analyzes the difference of domestic service input and foreign service input.Chapter 6 from the perspective of comparative advantage,selects panel data of multinational industries to empirically study the impact of digital trade on manufacturing RCA,and uses the mediation effect test to explores the relationship among digital trade,manufacturing servitization and manufacturing RCA.And further explored the impact of manufacturing servitization on manufacturing RCA.Based on the perspective of technology upgrading,Chapter 7 explores the impact of digital trade on manufacturing export technical sophistication,and uses the mediation effect test to examines the relationship among digital trade,manufacturing servitization and manufacturing export technical sophistication.Based on the perspective of global value chain upgrading,Chapter 8 empirically studies the impact of digital trade on the position of global value chain of manufacturing industry,and analyzes the relationship among digital trade,manufacturing servitization and the position of global value chain based on mediation effect model.Chapter 9 summarizes the research conclusions and points out policy suggestions and research prospects.This dissertation discusses the relationship between digital trade,manufacturing servitization and international competitiveness of manufacturing industry from the perspectives of international comparison,typical facts,theoretical derivation and empirical test.The main conclusions are as follows:Firstly,logical and theoretical research shows that the development of digital trade is conducive to the improvement of manufacturing servitization and international competitiveness of manufacturing industry,and manufacturing servitization is one of the ways for digital trade to improve the international competitiveness of manufacturing industry.Secondly,the development of global digital trade shows a good growth trend,and the development level of digital trade in developed countries is better than that in developing countries,but major developing countries show great development potential.During the sample period,China's manufacturing servitization and international competitiveness of manufacturing industry have been improved,but there is still a big gap compared with developed countries.Thirdly,the development of digital trade contributes to the improvement of manufacturing servitization,and the promotion effect of domestic service input is greater than that of foreign service input,which has certain guiding significance for the development of domestic producer service industry and global industrial integration.In addition,based on the differences of digital trade structure,country type,service input type and quality,manufacturing factor intensity and technology level,the impact of digital trade on manufacturing servitization is also different.Finally,digital trade has significantly promoted the international competitiveness of manufacturing industry,and manufacturing servitization is one of the effective ways for digital trade to enhance the international competitiveness of manufacturing industry.This dissertation measures the international competitiveness from different perspectives.Theoretical and empirical results show that digital trade has a significant impact on manufacturing RCA,export technical sophistication and position of global value chain,and mediation effect shows that manufacturing servitization is one of its influence ways.The influence of digital trade on the international competitiveness of manufacturing industry is obviously different based on country type,factor density and technology level of manufacturing industry.This dissertation enriches and expands the research on the economic effect of digital trade,the factors influencing of manufacturing servitization and international competitiveness of manufacturing industry.It provides support and reference for the development of digital trade and related policy making,and has certain enlightenment for the development of China's digital trade,the promotion of manufacturing servitization and international competitiveness of manufacturing industry. |
