Abstract

According to financial indicators of inputs and outputs of 15 listed companies on cloud computing information security concepts for 5 consecutive years since 2013 and based on the DEA Algorithm, this paper compared and analyzes features of comprehensive technical efficiency & scale efficiency and pure-technology efficiency & scale efficiency. The result demonstrates a decrease in comprehensive technical efficiency & pure-technology efficiency and an increase in scale efficiency. Besides, this paper makes a conclusion that the polarization of corporate scales, technologies and comprehensive efficiency in this industry is relatively serious and puts forward relevant suggestions to improve the invalid ratio of DEA.
