Research On The Impact Of RCEP’s Information Infrastructure On The Export Domestic Value-added Rate Of China

In the process of the evolution of the international division of labor,international trade has experienced international division of labor among industry and intra-industry trade,and now the new internal division of labor in products has been fully reflected in the global value chain.It is precisely because of the continuous decomposition of the cross-border production process that the trade in intermediate goods has surged,and the export domestic value-added rate(DVAR)that based on the value-added trade accounting have become more accurate methods to measure the profit of the foreign trade.At the same time,information and communication infrastructure has the advantage of spanning space,which can realize the rapid sharing of information resources on a global scale,more effectively promote the allocation of production factors such as capital and technology,improve the degree of modularity,reduce communication costs,and facilitate the participation of countries with cost advantages international trade.The Regional Comprehensive Economic Partnership(RCEP),which will come into effect in 2022,means that the flow of factors among member countries will be smoother,and information and communication infrastructure will play an increasingly important role in foreign trade.This article mainly consists of five sections.In the first part,the research context and the importance of this article will be explained,and the literature research methods will be used to summarize the relevant national and international research literature.In the second part,this article explains proper noun,introduces the relevant theories from the theoretical level,and derives the formula for the impact of information infrastructure on exports,mathematical model of domestic value-added rate to clarify the impact path.The third part builds an indicator system about information infrastructures by the method of principal component analysis(PCA),and uses statistical description and comparative analysis methods to analyze the RCEP national information infrastructure and my country’s export domestic added value.The fourth part uses the panel data analysis method from the empirical level to empirically study the impact of information infrastructure on the domestic value-added rate of exports.The fifth chapter summarizes the main conclusions of the article,and presents evidence-based policy recommendations according to the existing issues.The article mainly draws the following conclusions:(1)From 2007 to 2019,the development level of RCEP national information infrastructure has generally improved,and it is generally higher than the world average level.The information infrastructure of member countries has unbalanced development.The development of Southeast Asia is lagging behind,but the growth trend is more obvious.(2)During the sample period,China’s total export value to RCEP member countries and its domestic added value of exports continued to grow,and the growth rate of domestic addedvalue of exports was faster than the total export,and the rate of domestic added value of exports showed an upward trend,the domestic value-added rate of exports to Cambodia,Brunei and Singapore is above average.(3)In the composition of the domestic value-added rate of China’s overall export of RCEP,the value-added rate of exports in the form of final products for final consumption and the value-added rate of exports in the form of intermediate products account for the vast majority.(4)The improvement of information infrastructure has a significant role in promoting the domestic value-added rate of exports,and the impact on the domestic valueadded rate of exports in the form of final products is significantly greater than the impact on the domestic value-added rate of exports.The effect of information infrastructure on returned domestic value-added rate is not significant.China should continue to leverage its advantages of information and increase investment in information infrastructure projects in Southeast Asia;establish an international network cooperation platform to create a smoother trading environment;connect with new areas of the digital economy and build a high-level information network.
