Research On Technology Innovation Input And Enterprise Performance Based On DEA

Technology innovation investment is a high-investment and high-risk investment activity,which will have a crucial impact on enterprise performance.Many scholars discuss the relationship between technology innovation input and enterprise performance,as well as the influencing factors of technology innovation activities from different angles and levels.Most of them adopt the methods of theoretical and empirical analysis,and seldom study the cases Based on the theory of Data envelopment analysis and bench-marking,this paper discusses the relationship between technological innovation input and firm performance in the computer,communication and other electronic equipment manufacturing industry from the perspective of Technological Innovation Efficiency And through the comparative analysis of cases for practitioners to provide relevant decision-making.First of all,through the collection of literature on the concept of technological innovation input and enterprise performance,related theoretical development and literature at home and abroad to provide a theoretical basis for this paper.Secondly,58 listed companies in the computer,communication and other electronic equipment manufacturing industry of China's growth enterprise market were selected as research samples from 2015 to 2017,and the corporate factors were extracted as substitute indicators by using factor analysis method The efficiency Coefficient method is used to deal with the negative value in order to meet the requirement of input and output index in DEA model.The research object is analyzed from comprehensive efficiency,pure technical efficiency,scale efficiency,projection theory.Finally,using the Data envelopment analysis method to measure and evaluate the relative effectiveness ofmultiple inputs and outputs,and combining with the bench-marking theory,the bench-marking entity is selected as the bench-marking enterprise in the DEA efficient decision making unit The non-DEA effective decision-making unit selects the company to carry on the case contrast analysis,separately from the technical innovation input and the enterprise's profit ability,the development ability,the debt-paying ability,the operating ability four aspects to find out the enterprise performance existence question,propose the improvement direction,according to the research result put forward the related policy and the suggestion.
