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.

摘要： 基于PP-SFA模型对我国专利密集型产业产出效率进行测度，分析影响专利密集型产业产出效率的影响因素，并利用具有速度特征的时空演化模型分析专利密集型产业效率动态演化趋势。研究结果表明：我国专利密集型产业产出效率处于一般水平，仍有可提升空间，不同专利密集型产业间产出效率存在明显差异且发展不平衡。对于专利密集型产业产出效率影响因素，政府支持、研发投入强度、竞争程度、研发外部经费均对产出效率具有正向影响，但研发投入强度的作用效果最为显著。在时空演化方面，我国专利密集型产业产出效率呈现波动变化趋势。研究结果为专利密集型产业产出效率提升提供了理论支撑，并为专利密集型产业发展提供建议参考。
