Abstract:In this paper,DEA model and Malmquist index are combined to study the management efficiency of provincial natural science funds. The results show that the average efficiency of technology management is 0.895,the average of comprehensive management efficiency is 0.849,and the average of scale management efficiency is 0.956. There is a certain gap between the efficiency of technical management and the efficiency of comprehensive management. The efficiency of technical management is the main factor affecting the management efficiency of provincial natural science funds in China. The effectiveness of DEA calculation shows that the management efficiency of natural science funds in seven provinces is DEA effective level,while that of Shanxi,Hebei,Xinjiang and Liaoning is relatively low. From 2015 to 2019,the technical management efficiency of provincial natural science funds in China will decrease,and the main factor affecting the efficiency of comprehensive management is the efficiency of technical management. This paper proposes to clarify the functional positioning of provincial natural science funds, carry out project funding based on the characteristics of regional development, and establish an efficiency-based project performance evaluation system.
