The Impact Of US Export Control Of High-Tech Products On Innovation Of Chinese High-Tech Enterprises--An Empirical Study

Trade sanctions have always been an important issue in Sino-US bilateral relations.For a long time,the United States has initiated trade sanctions against China out of political and security considerations,especially in recent years.In the field of high technology,the United States has distorted the bilateral trade pattern between China and the United States by means of export control.The research question of this paper is:What kind of impact does the US high-tech product export control have on the innovation of chinese high-tech enterprises?This paper intends to analyze this influence through empirical research,and puts forward suggestions for high-tech innovation path under the new international political and economic situation.This article is divided into six parts.The introduction part introduces the background of the study.Among the many literatures on how trade sanctions policies affect the economy of sanctioned countries,although a certain number of literatures are from the micro perspective of enterprises,there is a lack of empirical research on sanctions incidents between China and the United States.Using data available in China,this paper also conducts research from a firm perspective.At the same time,in the Chinese academic circles,articles that study the US’s export control of high-tech products to China often focus on the horizontal comparison perspective of industries and countries,and mainly conduct research on trade data levels around issues such as trade volume and import and export trade margins.This study links enterprise innovation with trade sanctions,supplementing a new research perspective,and the conclusion of the empirical test also provides new empirical evidence for this field.The second part of the article explains and explains the concepts related to the topic of the thesis,enumerates different classification methods of high-tech products,and explains the reason why this article chooses the classification method of the National Bureau of Statistics.In addition,the second part also explains the relevant theories,involving leapfrog model,‘learing by importing’ theory and so on.The third part of this article reviews the history of US technology regulation on China.The process of U.S.technological control over China can be divided into six stages,among which the more important stage of influence is after the disintegration of the Soviet Union,when the political basis for joint resistance to the Soviet Union was lost between China and the U.S.,and the U.S.needs to re-examine its political and economic strategy toward China.In recent years,the United States has intensified its control over Chinese companies,increased the number of companies under control,and made relevant legal amendments for my country.This part analyzes the trade situation of ten major high-tech industries through G-L index and Brüelhart index.Through the analysis of the trade volume of high-tech products imported and exported by the United States to China from 2003 to 2013,it is found that the special time point of 2010 can be used as an exogenous shock time.The fourth and fifth parts of the article are carried out around the empirical research.This paper adopts the DID(difference in differences)method,sets the research time from 2007 to 2012,and takes 2010 as the policy occurrence year.After analyzing the policy effect,the parallel trend test and placebo test necessary for the DID method are supplemented.Next,this article distinguishes between whether the enterprise is a Chinese funded enterprise,whether it is a large-scale enterprise,and whether it is a processing enterprise,and studies the policy effects reflected in the nature of the enterprise.Finally,a mechanism test was conducted in the empirical section,and after explaining the impact mechanism using descriptive language,a simple econometric verification was conducted on the mechanism.The sixth part of this article is the conclusion,which indicates that strengthening technology export controls in the United States will inhibit the improvement of innovation capabilities of high-tech enterprises in China,and Chinese enterprises,larger enterprises,and general trade enterprises will be more significantly negatively affected.Based on empirical results,policy recommendations were proposed from two perspectives.The innovation of this article lies in conducting empirical research on the impact of US high-tech product export controls on China from a micro perspective of enterprises.The amount of data studied is relatively large horizontally,and the choice of policy research timing is unique.The main drawback of this article is that due to data availability issues,it is not possible to observe the impact of policy effects over a longer period of time.
