Evaluation on the Operation Efficiency of Medical Device Enterprises Under the Background of Digital Transformation —Empirical Analysis Based on DEA-Malmquist

Based on the panel data of 15 listed medical device companies in the Yangtze River Delta region of China from 2015 to 2020, this paper uses the DEA-BCC model and the Malmquist index to measure their operating efficiency. The results show that from a static point of view, the average comprehensive efficiency, the average technical efficiency, and the average scale efficiency of the listed medical device companies in the Yangtze River Delta region are 0.916, 0.947 and 0.965 respectively. The operating efficiency is affected by both the pure technical efficiency and the scale efficiency. From the dynamic point of view, the operating efficiency of listed medical devices companies in the Yangtze River Delta region is fluctuating; The digital transformation of medical device enterprises is still in the initial stage. Based on the above research, this paper puts forward some countermeasures and suggestions, such as strengthening the independent innovation ability of Chinese medical device enterprises, accelerating the process of digital transformation, and increasing the government's support.
