The Regional Difference And Cause Analysis Of Chinese University Scientific Research Investment Efficiency

Today,with the rapid growth of science and technology,innovation in science and technology has played a pivotal role in ensuring economic growth,improving people’s livelihood and ensuring major national security.In China,institutions of higher learning,as one of the main places to carry out exploratory and creative scientific research activities,are the main power source to promote the rapid development of local scientific research,technology and social economy.Therefore,under the background of implementing innovation-driven development strategy and regional coordinated development strategy in the new era,it is of great significance to accurately understand the status quo and regional differences of scientific research efficiency of colleges and universities,which are the core force of scientific research,in order to comprehensively improve the input-output efficiency of scientific research of colleges and universities.Taking Chinese universities as research objects,this research analyzes the current situation of input and output of scientific research from horizontal and vertical perspectives.Then,under the framework of stochastic frontier analysis,the output efficiency of basic knowledge and applied knowledge of Chinese universities is measured,and the Thiel index method is used to reveal the regional differences in the efficiency of scientific research input-output.Finally,the QAP method is used to identify the causes of regional differences between basic knowledge output and applied knowledge output efficiency from four aspects: policy support intensity,capital input,human input and scientific research competitiveness.The research results show that the input-output efficiency of university research varies greatly in different regions.From the perspective of eight comprehensive economic zones,the lowest output efficiency of the two types is in the Great Northwest region,while the highest output efficiency is in the eastern coastal region,and there is a spatial aggregation effect between the high output efficiency regions.From the change and decomposition of the total Thiel index of scientific research efficiency,it is found that the Thiel index of the eight regions of various knowledge output is decreasing year by year,indicating that the equilibrium of regional scientific research efficiency has been improved,and narrowing the gap of scientific research efficiency of universities within the region is the key factor to achieve balanced development.The further analysis of the causes of the differences in scientific research efficiency shows that: for the regional differences in the output efficiency of basic knowledge,the differences in the total amount of human capital input and the title structure of researchers are the main causes of the differences in the output efficiency of basic knowledge,and the reduction of the differences in local scientific research funds will not promote the balanced development of the output of basic knowledge.For applied knowledge,regional differences in policy support become the decisive force for regional differences in scientific research efficiency.Finally,it is suggested that we should broaden the source of funds and optimize the allocation structure of scientific research funds.Create a loose and free funding system for scientific research projects;Formulate research support policies according to local conditions,taking full account of differences between different regions;We will establish an effective talent incentive mechanism and optimize the professional title structure of scientific researchers.
