Abstract: Based on the PP-SFA model, the paper measures the output efficiency of patent-intensive industries in China, and analyzes the influencing factors affecting the output efficiency of patent-intensive industries. Also, the dynamic evolution trend of patent-intensive industries is analyzed by using the spatial-temporal evolution model with the characteristic of speed. The research results show that the output efficiency of patent-intensive industries in China is at a general level, and there is still space for improvement. The output efficiency of different patent-intensive industries is obviously different and the development is unbalanced. For the factors affecting the output efficiency of patent-intensive industries, government support, R&D investment intensity, competition level, and R&D external funds all have positive effects on output efficiency, but R&D investment intensity has the most significant effect of all. In terms of spatial-temporal evolution, the output efficiency of patent-intensive industries in China shows a fluctuating trend. The research results provide theoretical support for the efficiency improvement of patent-intensive industries, and provide suggestions for the development of patent-intensive industries.
