Can Enterprise's Technology Innovation Promote The Domestic Value-Added Ratio Of Export?

With the continuous development of international trade and the deepening of the international division of labor,the value creation chain of product production(R&D,design,production,marketing,logistics,etc.)has been split into all the world,international trade is no longer entirely dominated by final products,which leads to a country's exports of products are not entirely produced by the country.It also contains a lot of intermediate and semi-manufactural imported goods from abroad.In this context,the trade in value-added statistics mode came into being,and the export domestic value-added ratio is an important way to show this index.According to the existing research results,compared with developed countries and some developing countries,Chinese enterprises' export domestic value-added ratio is relatively low,so it is particularly important to study how to improve the domestic value-added ratio of enterprises,which is directly related to a country's position in the global value chain,real trade gains.The Xi Jinping's report at 19 th CPC National Congress clearly point the implementation of innovation-driven development strategies and the establishment of innovative countries.Under this background,this paper draws on the existing mathematical model,deduces the theoretical expression of the influence of enterprise technological innovation on the domestic value-added ratio of export,and finds that the technological innovation of enterprises promotes the export domestic value-added ratio of enterprises by increasing the relative price of imported intermediates and the quality of intermediate inputs,and then according to the different heterogeneity of enterprises,the relevant hypotheses of this paper are put forward.This paper combines the Chinese Industrial Enterprises Data and Chinese Customs Trade Data in 2000-2006,calculates the relevant indexes,and further analyzes the annual trends of the two core indexes of enterprise technology innovation and export domestic value-added ratio of enterprise.By using the bidirectional fixed effect model and controlling the clustering robust standard,the influence of enterprise technological innovation on the domestic value-added ratio of export,and the effect of heterogeneities on this influence are investigated,then the relevant robustness test is carried out.It is found that:(1)The technological innovation of enterprises can significantly promote the export domestic value-added ratio;(2)The impact of technological innovation on the domestic value-added rate of exports is effected by the heterogeneity of enterprise ownership,while the impact of technological innovation on the value-added rate of domestic exports is not significant for stateowned enterprises,while the impact of technological innovation on the value-added rate of domestic exports is significant for other ownership types of enterprises;(3)the impact of technological innovation on the domestic value-added rate of exports is affected by industry heterogeneity.The technological innovation of enterprises in high-tech industries has the strongest effect on promoting the domestic value-added rate of exports;(4)Because of the regional heterogeneity caused by the difference of economic development and system construction level in different regions,enterprises in eastern regions have the strongest effect on promoting the domestic value-added rate of exports.(5)The heterogeneity of trade modes leads to that the technological innovation of processing trade enterprises has the strongest effect on the domestic value-added rate of exports compared with other trade modes;(6)The impact of technological innovation of enterprises on the domestic value-added rate of exports is effected by the heterogeneity of scale,and the effect of technological innovation of larger enterprises on the domestic value-added rate of exports is lower than that of smaller enterprises.Enterprises' technological innovation promotes the domestic value-added rate of exports.The above findings provide a new perspective for promoting the improvement of export domestic value-added ratio and expanding trade profits,and provide the necessary policy basis for the implementation of China's innovation-driven development strategy under the background of deepening the division of labor within international trade products.
