Research About The Effect Of Technological Innovation On The Dual Margin Of China's High-tech Product Export Growth

Since the beginning of the 21st century,China's exports of high-tech products have continued to grow,and the export of high-tech products has become one of the important engines of China's foreign trade exports.Despite this,the added value of China's high-tech product exports has not really improved.China's high-tech industry has a low level of overall technological innovation.The key core technologies and high-end equipment have a high dependence on foreign trade.High-tech products participate in the international division of labor and continue the "two outside" mode.The high-tech industry is still at the low end of the global value chain,and has not yet formed a complete industrial chain.It can be seen that technological innovation has played a key role in the continuous evolution of high-tech product exports from continuous and extensive growth to value-added exports.In theory,technological innovation can promote the growth of the number and variety of high-tech products by increasing the production efficiency of high-tech products,creating new products,and improving product quality,thereby enhancing its international competitiveness.Based on the heterogeneous enterprise trade theory,this paper systematically examines the impact of technological innovation on the dual margin of China's high-tech product exports.The research in this paper not only helps to enrich the heterogeneous enterprise trade theory,but also provides new ideas for China to enhance the international competitiveness of high-tech product exports and foster new competitive advantages.It can also provide decision-making reference for accelerating the construction of innovative countries.This paper takes China's data on the export of high-tech products from 132 economies as a sample,systematically analyzes the status of China's technological innovation and the export of high-tech products,and the dual margin impact mechanism of technological innovation on the export of high-tech products.The econometric model is used to empirically study the impact of technological innovation on China's high-tech product exports,and the heterogeneity of this effect in different economic development economies.The main contents and conclusions of the full text are as follows.The first chapter is the introduction.It mainly expounds the research background and significance of this paper,and combs the contribution of the extensive and intensive margins to the growth of export,the impact of technological innovation on the dual margin of export growth.Based on the literature related to the dual margin impact of technological innovation on the growth of high-tech products,this paper proposes the research content,ideas and research methods,as well as the innovation and deficiency of the research.The second chapter is the theoretical basis and mechanism analysis.Firstly,combing and summarizing the theories related to the research of this paper,including the theory of technological innovation,the new trade theory,the new factor theory of international trade,the theory of competitive advantage and the theory of heterogeneous enterprise trade.Secondly,from the three channels of improving production efficiency,creating new products and improving product quality,the paper analyzes the impact mechanism of technological innovation on the extensive and intensive margins of high-tech products export.The third chapter is the status quo of China's technological innovation and the export of high-tech products.Firstly,from the two aspects of technology input and output,the development of China's technological innovation from 2003 to 2017 is analyzed.The results show that the absolute level of China's technological innovation has been increasing in recent years.The fluctuation is relatively large,that is,the increasing trend of China's technological innovation level is not stable.Secondly,the dual margin changes of China's exports of high-tech products to the world,different types of economies and major high-tech products trading partners were measured and analyzed.It is found that,on the one hand,whether it is exporting to the world,or exporting to different types of economies,or exporting to major trading partners,the extensive margin of China's high-tech products exports is higher than the intensive margin.The growth rate of intensive margin is higher than extensive margin,which means that the growth of China's high-tech product exports in recent years is more driven by the intensive margin;on the other hand,China's growth rate of the extensive and intensive margins of high-tech products exports to developing economies is less than the growth rate of the extensive and intensive margins exports of high-tech products in developed economies,indicating that the growth of China's high-tech products exports is driven by the growth of exports to developed economies.The fourth chapter is the empirical research on the technological innovation affecting the dual margin of China's high-tech product export.This chapter adopts the FGLS estimation method of panel data.Firstly,it empirically studies the effect of technological innovation on the extensive and intensive margins of China's high-tech product export intensive from the overall sample level.Secondly,according to the difference of economic development degree,the overall sample is further divided into two sub-samples of developed economies and developing economies,and the heterogeneity of technological innovations on the dual margin effects of high-tech products is examined.Finally,the replacement technology innovation is adopted.the model conclusions are tested for robustness.It is found that,on the one hand,technological innovation can significantly promote the extensive and intensive margins growth of China's high-tech products,but this effect has obvious heterogeneity in different types of economies.In the sample of developed economies,technology Innovation has no significant impact on the extensive and intensive margins.In the sample of developing economies,the impact of technological innovation on the extensive and intensive margins is significant.On the other hand,in addition to technological innovation,relative economic scale,trade costs,labor productivity of high-tech industries,multilateral resistance,external shocks,and the signing of free trade agreements have a certain impact on the dual margin of China's high-tech product exports,and impact effects also show some heterogeneity in different types of economies.The fifth chapter is conclusions and policy recommendations.On the basis of summarizing the conclusions of the full-text research,This paper from the increase of high-tech industry R&D investment,and constantly enhance the ability of independent innovation,attach importance to technology introduction,technology to promote independent research and development capabilities,improve the productivity of high-tech products,to promote the construction of free trade zones and trade facilitation.To solve the deep-seated contradictions that restrict trade development,it puts forward policy recommendations to further promote China's technological innovation and improve the competitive advantage and the dual margin growth of high-tech products.The innovation of this paper is mainly reflected in two aspects:Firstly,combining technological innovation with the dual margin of export,and studying the impact of technological innovation on the growth of China's high-tech products export from the perspective of the extensive and intensive margins.It provides a new perspective for studying the relationship between innovation and exports.Secondly,on the basis of empirical analysis of technological innovations on the extensive and intensive margins effects of China's high-tech products exports,the paper further studies the heterogeneity of this impact effect among trading partners of different types of economic development.
