Data envelopment analysis is an efficiency measurement
method proposed by Charnes, Cooper and Rhodes in 1978, including CCR model
efficiency analysis and BCC model efficiency analysis, which is used to
evaluate the relative efficiency of decision-making units. The measured
efficiency value is the most favorable result of the evaluated unit under
objective circumstances.
This article applies data envelopment analysis method
to evaluate the performance of listed companies in Taiwan's tourism industry.
After analysis, it was found that the total efficiency of the six tourism
industries including Huayuan, No. 1 Store, Gourmet KY, Wangpin, Xiongshi, and
Holaday is effective, while the total efficiency of the three tourism
industries including Farglory, Phoenix, and Xintiandi is not Effective, but
technical efficiency is still effective. Except for the tourism industry whose
total efficiency is effective, its returns to scale remain unchanged. Two
tourism industries, such as Guobin and Jinghua, have diminishing returns to
scale because their return to scale value is >1 and should reduce their
business scale. The returns to scale of other tourism industries are all
Increasingly, it is recommended to expand the scale of operations.
