Commercial Bank Technology Finance Input Efficiency Evaluation Study

Since the 21 st century,China's economy has developed rapidly.At present,the economic development model has entered the critical period of the "new normal" of the "three-phase superposition".Science and technology have advanced by leaps and bounds,and innovation has been driven to accelerate the development of science and technology enterprises.And finance is taking an increasingly important position.In2019,with the establishment of the Shanghai Municipal Science and Technology Bank,it demonstrated the state's strong support for science and technology finance investment,and encouraged enterprises to independently innovate and promote technological progress by increasing policy support for technology-based enterprises.Finance is one of the important driving forces for the advancement of science and technology.Commercial banks are the main source of funding for science and technology finance.Therefore,the issue of the investment and efficiency of commercial banks in science and technology is increasingly concerned by the academic community.The research content of this paper mainly includes five parts: introduction,theoretical basis,measurement method introduction,empirical research and countermeasures.In the introduction part,it includes the background introduction,combing the research significance,sorting out the relevant literature research,understanding the current development of science and technology finance,completing the data collection and finishing,and researching the measurement method of the scientific and technological financial investment efficiency of commercial banks based on the theory of relevant research.The model was transformed,and the empirical research on the efficiency of commercial banks' financial investment was conducted.The reasons were analyzed and relevant countermeasures and suggestions were proposed based on the conclusions.In theory,this paper summarizes the connotation of science and technology finance and the status quo of technology finance development at home and abroad.It sorts out the theory of financial innovation,the theory of capital allocation efficiency,the theory of input-output efficiency,and provides a theoretical basis for studying the efficiency of investment in science and technology finance of commercial banks.Introduced the relevant methods of scientific and financial efficiency evaluation,and built a comprehensive index system for the efficiency of commercial banks' financial investment.This paper explains the reasons for using the three-stage DEA and Malmquist index methods,and explains the meaning of each index.In the empirical part,this paper takes the commercial bank's technology financial investment and scientific and technological output as the starting point.Firstly,it constructs the three-stage DEA model and the Malmquist model to evaluate the performance of commercial banks' financial investment.Then,according to the principle of index selection,select the amount of technology loans,the number of enterprises that issue technology loans in the current period,and the technology equity pledge loans as input indicators,and select the sales revenue of high-tech new products and the turnover of technology contracts as output indicators,from 2012 to2016.The China Science and Technology Statistical Yearbook,CSMAR Database,and EPS Data Platform collect relevant data.Then use the three-stage DEA model and Malmquist model to analyze and evaluate the performance of commercial banks' financial investment in science and technology.Based on the empirical analysis,it is concluded that the comprehensive efficiency value of commercial banks' financial investment is low,which is basically affected by scale efficiency.However,it is less affected by pure technical efficiency and is greatly affected by environmental variables.Finally,based on the empirical results,it proposes countermeasures to improve the performance of commercial banks' financial investment in science and technology: innovative commercial banks' investment in science and technology finance,improvement of policy support for technology-based enterprises,support for multi-channel financing of technology-based enterprises,and improvement of technological innovation enterprises.Investment Environment.
