Research On The Impact Of R & D Investment Jump On Enterprise Innovation Performance

In the context of a new round of scientific and technological revolution and the accelerated advancement of world industrial reform,as the first driving force to lead social and economic development,the innovation is crucial to the sustainable development of a country.The innovation behavior of enterprises is closely related to the investment of R&D funds.So it is undoubtedly a necessary way for enterprises to increase the investment of R&D funds,If companies want to improve their market position and get competitive advantage in the current competitive environment.However,in the digital economy,the research on the relationship between R&D investment jump and enterprise innovation performance,it is still in its infancy and cannot meet the urgent need for high-quality development of the current social economy.Therefore,the research on this issue has also become one of the research focuses of the current academic discussion and research.Based on relevant theories and the relationship between R&D investment jump and enterprise innovation performance,this paper introduces application of digital technology as an intermediary variable between R&D investment jump and enterprise innovation performance.This paper selects listed companies in the electronic equipment manufacturing industry and software and information technology service industry of Shenzhen and Shanghai A-shares as the research object,selects 520 listed companies’ panel data from 2015-2021,and uses STATA16.0software for data processing and empirical analysis.Firstly,the paper carries out descriptive analysis to judge whether the data is reasonable.Secondly,the paper carries out relevant analysis to preliminarily judge the relationship between variables,Before the regression analysis,multiple linear analysis,F test and Hausman test are carried out to determine the model of regression analysis.Finally,the main effect of R&D investment jump on enterprise innovation performance and the intermediary effect between application of digital technology are tested by the individual fixed effect model of multiple regression.At the same time,the substitution variable is used for robustness test.The empirical results of this study show that different states of R&D investment jump have different effects on enterprise innovation performance;The jump in R&D investment will promote the application of digital technology of enterprises;Application of digital technology has a positive impact on enterprise innovation performance;Application of digital technology plays an intermediary role between R&D investment jump and enterprise innovation performance.Based on the above analysis,this paper has important practical implications for enterprise R&D investment management and enterprise digital technology application,as follows:whether enterprises need to maintain stable R&D investment depends on the specific situation;Enterprises should pay attention to application of digital technology in R & D investment jump to enterprise innovation.
