Abstract: Medical device companies of SSE STAR Market are of great significance in breaking through key core technologies, improving independent innovation ability and enhancing international competitiveness. However, no scholar has studied the innovation efficiency of these companies. In this paper, a three-stage DEA model is firstly used to conduct a cross-sectional analysis of the innovation efficiency of 35 medical device companies of SSE STAR Market in 2021. Then the DEA-Malmquist index model is used to dynamically analyze the change of their innovation efficiency from 2019 to 2021 by eliminating the environmental factors and random error interference in stage two. The results of the three-stage DEA model show that the innovation and development of medical device companies of SSE STAR Market in 2021 is mainly driven by management and technical factors. Without considering the influence of environmental factors and random errors, the overall innovation efficiency of medical device companies is underestimated. The results of DEA-Malmquist index model show that the overall innovation efficiency of medical device companies of SSE STAR Market kept improving during 2019 to 2021. Among concerned efficiencies, the utilization efficiency of innovation resources improved, the pure technological efficiency improved significantly but the technology was not fully utilized, and the innovation input exceeded the optimal investment scale. Generally, the innovation efficiency of medical device companies of SSE STAR Market improved from 2019 to 2021, but the overall innovation efficiency was still low. The increase of provincial per capita GDP, government subsidies and asset-liability ratio is not favorable to the reduction of the redundancy of capital and manpower input of enterprises in the process of technological innovation. Enterprises should be encouraged to transfer low-value production to provinces with lower production costs. At the same time, medical device companies in cities with relatively low per capita GDP should be encouraged to seek financing from SSE STAR Market.

Key words: SSE STAR Market, medical device companies, innovation efficiency, three-stage DEA, DEA-Malmquist index
