The Study On The Promotion Of Global Value Chain Upgrade By Economic And Trade Cooperation Of "The Belt And Road"

"One Belt One Road" is that,under the new economic norm,China actively adapts to the new changes of the structure of international economic and trade,and is engaged in economic and trade cooperation with Asian-European-African bilateral trade,two-way direct investment and international financial cooperation,so as to promote the sustained and rapid growth of the national economy along the Belt and the new opening strategy of transformation and upgrading of value chain.Policy communication,facilities connectivity,trade flow,capital integration,popular connection are the key content to build "One Belt One Road",and the cooperation of trade,investment and financial to promote the transformation of value chain along the Belt is regarded as the top priority.In the new era of rapid growth of the global value chain competition pattern,acceleration of the reconstruction of the global economic and trade system and rapid rise of the new production organization mode,how to realize the transformation and upgrading of the national value chain along the Belt through building economic and trade cooperation becomes a major theory and practice waiting to be solved between countries.According to the structure of "total-sub-total" arrangements,the paper comprehensively use the research methods of induction and deduction,statistics and comparison,theory and practice.First of all,through the combing of the relevant literature research to defy the connotations and the concept and systematically elaborate the theoretical logic and the analysis framework of how the economic and trade cooperation promotes the upgrade of value chain.Secondly,try to give the inherent mechanism of logical self-consistency from the six chapters,and use the theoretical model and empirical analysis to demonstrate that the economic and trade cooperation promotes the value chain upgrade.Finally,put forward the path selection for the Belt to upgrade the value chain though the economic and trade cooperation.The conclusions of the research mainly include:Firstly,the status of global value chain are very different among countries along the Belt.The intra-product specialization,trade liberalization and the deepening and accelerating effect on intra-product specialization together constitute an important mechanism to promote the upgrading of value chain.Secondly,the difference between heterogeneity demand and network supply is very prominent,and the theoretical analysis and empirical test results support the development mechanism of heterogeneous demand and the network supply internally and cooperatively promoting the upgrade of national value chain.Thirdly,a set of systematic investment facilitation index system is used to study the index and comprehensive level of investment facilitation along the Asia-Europe and Africa countries.The timing and regional differences of the investment facilitation level are very prominent along the Belt.The empirical results show that the factor endowment structure,investment facilitation and so have a significant positive effect on the value chain upgrade.Fourthly,the study method of mathematical model combined with the empirical test shows that the two-way FDI can accelerate the promotion of the development of the value chain of the host country and the home country through the double technology spillover and its technology transmission efficiency.Fifthly,the construction of mathematical model proves that the direct or the indirect financial development can promote the upgrading of value chain,the currency internationalization,financial market efficiency and other countries have a significant positive impact on the value chain upgrade,and the financial cooperation can promote the value chain to upgrade the development mechanism.Overall,the paper aims to grasp the core issue of the economic and trade cooperation promoting the national value chain along the Belt in order to give the logical self-consistent transformation mechanism on the value chain from trade,investment and finance.Finally,put forward the choice of path with theoretical and evidence support on this basis.The innovation of the paper is reflected in the following aspects:First,in different mechanisms or the role of the path,the paper gives the core logic of the upgrade of national chain by using the systematic and innovative thinking and almost all statistical data of countries along the Belt which,to a certain extent,can overcome the subjective.Second,based on the principle of modular division,the paper for the first time builds up a theoretical framework which shows that the heterogeneous demand and the network supply collaboratively promote the transformation and upgrading of the value chain and from a quantitative point of view confirms this important development mechanism.The third is to build a system of investment convenience measurement system for the first time which comprehensively describes the Asian-European and African investment facilitation level,and brings it into the analysis framework of value chain upgrade.Fourthly,it reveals the dual technology spill mechanism of investment cooperation to promote the upgrading of value chain.Bring the integration of monetary internationalization and financial efficiency into the analysis framework of financial cooperation promoting the value chain.The innovative conclusions are of great theoretical significance and practical value to foreign trade policy of foreign countries.
