影响知识产权密集型产业创新效率的因素差异分析

大力发展知识产权密集型产业是形成产业整体竞争优势的重要举措，提升区域知识产权密集型产业创新效率有助于推动产业转型升级和提升经济就业贡献。研究以浙江省33个知识产权密集型产业为样本，基于创新价值链开展创新效率评价和关键因素识别，发现生产规模和发明专利申请量是影响创新效率的关键因素且发挥正向影响，政府资金对创新效率发挥消极影响，而研发经费内部支出、消化吸收经费支出和有研发活动企业数等影响作用不显著。这说明区域知识产权密集型产业发展存在研发投入产出不匹配的短板，为提升知识产权密集型产业创新效率提供了针对性的对策建议。

Study on the difference influence factors of innovation efficiency of regional intellectual property intensive industries

mproving the innovation efficiency of regional intellectual property intensive industries helps to promote industrial transformation and upgrading, to advance economic and employment contribution. The study takes 33 intellectual property intensive industries in Zhejiang Province as samples, based on innovation value chain, to evaluate the innovation efficiency and identificate its key factors. The research conclusion shows that the production scale and the amount of invention patent applications are the key factors affecting the efficiency of innovation, which plays a positive effect, the government funds plays a negative impact on the innovation efficiency. There are three non-significant factors, namely R&D expenditures, expenditure on digestion and absorption, number of enterprises with R&D activities. This shows that the development of regional intellectual property intensive industries has a short board，which does not match the R&D input and output, and provides some suggestions for improving the innovation efficiency of intellectual property intensive industries.
