Abstract: Scientific research instrument and equipment are the basic conditions and important means of scientific and technological innovation. In recent years, with the strong support of the state for the“double first-class”subject construction, the number of large-scale instrument and equipment in universities has been increased. Therefore, how to use and manage instruments scientifically and improve the open sharing rate of large-scale instrument and equipment has become an urgent problem for domestic universities. This paper discusses the problems existing in the open sharing of large-scale instrument and equipment based on the new large-scale instruments purchased by the analysis and testing center of Jiangnan University. It is proposed to build an open sharing and efficiency-enhancing system of large-scale instrument and equipment in university by means of the sharing benefit evaluation database of large-scale instrument and equipment, the digital sharing resource platform, the perfect personnel training system and the development of new functions of instrument and equipment, give full play to the resource advantages of large-scale instrument and equipment in university and assist the scientific and technological innovation of the country and society.

Key words: Large-scale instrument and equipment, Open sharing rate, Efficiency-enhancing system, Colleges and universities, Science and technology, Innovate
