The Effect On Technology Progress Of The ICT Industry Of China By The Trade Friction Between China And America

The China-US trade war between 2017 and 2019 has had a big impact on the economy of China,the United States and the world.Although the two countries have reached the agreement,given the contradictions between China and the United States in terms of the differences of economic structure,policy and culture,national development strategies and dynamic comparative advantages,this article considers that the trade friction between the two countries is inevitable and long-standing.Focusing on the intensification of trade frictions between China and the United States,the United States has adopted a series of trade sanctions and trade restrictions to hinder the technological progress of Chinese ICT industry.At the same time,China is in a critical period of industrial structure adjustment and economic development to improve quality and efficiency,and technological progress plays an important role in it.At present,most of the academic circles research on the impact of increasing trade frictions is limited to qualitative analysis and trade impact.Quantitative analysis and research on the impact of industrial technology progress are relatively few.Therefore,it is of theoretical and practical significance to study how the trade friction affects the technological progress of Chinese ICT industry and formulate policies based on the analysis results.Based on the perspective of the current situation,this paper first uses DEA model and statistical methods to analyze the technological progress of Chinese ICT industry,the measures taken by the United States to Chinese ICT industry,and how the trade friction affects the current technological progress of Chinese ICT industry.Secondly,from the perspective of theoretical analysis,this paper analyzes the reasons why the trade friction affects the technological progress of Chinese ICT industry with a technology innovation game model,learning by doing model,technology introduction model,and intermediate product import model.Finally,based on the data of1991-2018 total factor productivity growth of Chinese ICT industry and the trade restriction intensity of US-China ICT industry,the impulse response function and variance decomposition are used to analyze how the trade friction affects the technological progress of Chinese ICT industry through PVAR model.It is concluded that the trade friction between China and the United States will have a negative impact on the technological progress of Chinese ICT industry in the short term,and have a positive impact on the technological progress of Chinese ICT industry in the long term.Based on the conclusions of this study,the following suggestions are given.Enterprises should strengthen trade compliance,diversify importing countries,and increase the intensity of independent R&D.The industry should effectively innovate,conduct differentiated R&D,and build supply chains.The state should formulate countermeasures,set up response mechanisms,and improve the environment of R&D.
