Research On The Influence Mechanism Of U Pstream Monopoly On Enterprise Innovation

With the continuous transformation of the global economic structure,technological innovation has become a necessary way for enterprises to gain a competitive advantage in market competition.Innovation is the primary driving force for development and a strategic support for building a modern economic system.The report of the Nineteenth National Congress clearly pointed out that by 2035,China will rank among the top of innovative countries.However,at present,China's scientific and technological foundation is still weak,and its scientific and technological innovation capabilities,especially its original capabilities,are still far from the world's strong science and technology countries.Core technologies in key areas are still largely controlled by others.At present,under the background that market competition has basically been achieved in China's downstream industries,and the degree of upstream monopoly is still high,corporate innovation will be affected by upstream monopoly under the role of vertical correlation.Therefore,it is of great research value to study how upstream monopolies affect the innovation of downstream enterprises and analyze the impact mechanism.This article theoretically analyzes how upstream monopolies affect corporate R&D innovation through corporate profits and corporate exports,and puts forward research hypotheses accordingly.Utilizing the database of Guotai'an listed companies and China's input-output table in 2012,the fixed-effect model is used to empirically study the impact of upstream monopoly on the number and structure of patent innovations in enterprises and the channels of influence,and further study the differences between enterprises with different technological levels The effect of different levels of downstream government subsidies and downstream market concentration on this effect.The research results show that:(1)the higher the degree of upstream monopoly facing a company,the lower the number of patent innovations;(2)the upstream monopoly suppresses the number of innovations in invention patents and utility model patents,but the impact on design patents is not significant(3)upstream monopoly has weakened corporate innovation through the two channels of suppression of corporate profits and corporate exports;(4)the inhibitory effect of upstream monopolies on corporate innovation varies between industries with different technological levels.Upstream monopoly can significantly affect the R&D and innovation of non-technical enterprises,but the impact on the R&D and innovation of technological enterprises is not significant.(5)The greater the downstream government subsidy,the higher the market concentration,and the weaker the inhibition of upstream monopoly on corporate innovationAt the end of the article,based on increasing competition in the upstream industry and increasing R&D subsidies for downstream enterprises,the paper proposes policy recommendations from the perspective of the government and enterprises,and proposes future research prospects.
