Abstract Objective To study the current situation and influencing factors of innovation efficiency of pharmaceutical enterprises, and provide a scientific basis for improving the innovation efficiency of pharmaceutical enterprises. Methods The number of personnel and expenditures in pharmaceutical enterprises’ research and development were used as input indicators, and the number of patent applications was used as output indicators, the stochastic frontier production function model was used to calculate and compare the innovation efficiency of three types of pharmaceutical enterprises in chemical drug manufacturing, Chinese patent medicine manufacturing, and biological drug manufacturing from 2009 to 2019. Results The overall innovation efficiency of pharmaceutical enterprises showed a fluctuating upward trend. The elastic coefficients of the number of research and development personnel and the number of research and development expenditures were 25.285 (P < 0.01) and -9.164 (P < 0.01), there was a phenomenon of insufficient human investment and excess capital investment. The scale of enterprise innovation subject, the scale of research and development personnel, and the scale of research and development expenditure were the promoting factors of patent output efficiency, but the enthusiasm of enterprise research and development showed a restraining effect. Conclusion The overall innovation efficiency of pharmaceutical enterprises shows an upward trend, but there are problems such as insufficient research and development investment, low allocation efficiency, and uneven industry development. It is urgent for all relevant parties to increase the investment intensity of research and development resources in the pharmaceutical enterprises and optimize the allocation, improve industrial policies to achieve systematic management, and encourage pharmaceutical companies to change their operation and management thinking to improve management quality.
