Research on the Evaluation of Supporting Ability of “Double-First Class”University Libraries Based on the Principal Component Analysis and Cluster Analysis

Abstract

Based on the data at the end of 2016 and selecting 12 variables such as building area and paper resource purchase fee, this paper uses principal component analysis and cluster analysis to evaluate the support ability and overall strength of 42 universities and colleges under “double-first class” construction. At last, ranking and classifying the university libraries according to the research results. This study has shown that the number of staff members, the purchase fee of electronic resources, paper resources, literature resources, the number of published paper and the number of paper resources are the main factors affecting the construction of university libraries. The gap in support ability among university libraries in the same region, different provinces and cities, and different types are obvious; the imbalance of libraries' own strength leads to their inefficiency; the strength of university libraries does not match the strength of scientific research. It is recommended that universities and colleges should allocate funds reasonably, increase the investment and attention in libraries, and strengthen exchanges and cooperation between university libraries in and between regions.
