中文摘要:

[目的/意义]我国污水处理行业地区创新发展和产学研创新产出不均衡现象较为突出，解构专利产出驱动因素，揭示其时空演变特征，为促进行业创新区域均衡发展提供决策依据。[方法/过程]基于专利文本分析、LMDI分解模型和空间自相关分析方法对我国2000―2023年污水处理行业产学研专利授权量的空间动态演变及驱动因素进行分析，并探讨主要驱动效应在省区尺度的空间差异特征。[局限]受数据所限，没有开展研发经费投入、区域经济水平等因素影响下的驱动效应分析。[结果/结论]研究表明2015年开始专利数量增幅明显增大，2020年达到峰值，C02F1/00、C02F1/28分类下的专利申请量增幅显著。节能环保产业规模效应和污水处理行业份额效应是驱动产学研专利授权量增加的主要因素。产学研内驱效应有明显差别，企业内驱效应在研究期内正负交替，院校和科研单位在大部分时期以负效应为主，研究期末表现出明显的正效应。企业和院校的内驱效应在省区空间尺度上呈现显著聚集特征。

英文摘要:

[Objective/Significance] The imbalance between regional innovation development and Industry-University-Research Institute innovation output in China’s sewage treatment industry is quite prominent. Deconstructing the driving factors of patent output, revealing its spatiotemporal evolution characteristics, and providing decision-making basis for promoting regional balanced development of industry innovation. [Methods/Processes] Based on the patent text analysis, LMDI decomposition model, and spatial autocorrelation analysis method, this paper analyzes the spatial dynamic evolution and driving factors of Industry-University-Research Institute patent authorization in China’s sewage treatment industry from 2000 to 2023, and explores the spatial differences of the main driving effects at the provincial scales. [Limitations] Due to data limitations, no analysis was conducted on the driving effects of factors such as research and development funding investment and regional economic level.[Results/Conclusions] Research has shown that since 2015, the number of patents has increased significantly, reaching its peak in 2020. The number of patent applications under categories C02F1/00 and C02F1/28 has also increased significantly. The scale effect of the energy-saving and environmental protection industry and the share effect of the sewage treatment industry are the main factors driving the increase in the number of patent authorizations. There should be a significant difference in the internal driving effect of Industry-University-Research Institute. The internal driving effect of enterprises alternates between positive and negative during the research period, while the negative effect is mainly observed in universities and research institutions during most of the period. At the end of the research period, there is a clear positive effect. The internal driving effects of enterprises and universities exhibit significant clustering characteristics at the provincial scale.
