Comparative Study of Input-Output Efficiency on College Scientific Research

This paper deals with studying input-output efficiency of scientific research in colleges and universities by using the method of principal component analysis. A mathematical model including multiple scientific research input-output indicators of colleges in 31 provinces, autonomous regions and municipalities directly under the central government are built to make further quantitative analysis and comparative studies. As a result, higher input doesn´t lead to higher output or higher input-output efficiency. Effective operational mechanisms should be set up to ensure the close correlation between input and output and to improve input-output efficiency.
