气候变化背景下中国潜在颠覆性低碳技术识别及其分布特征研究——基于专利被引次数的POT模型

Study on the Identification and Distribution Characteristics of Potential Subversive Low Carbon Technology in China under the Background of Climate Change—Pot Model Based on the Number of Times of Citations

颠覆性低碳技术创新是深入实施创新驱动战略,推动全社会低碳转型的重要手段。基于EPO与USPTO联合公布的CPC-Y02低碳专利分类,首次采用POT模型对中国2004~2013年264,444件低碳技术专利的被引次数进行分析,识别潜在的颠覆性低碳技术,并分析技术的领域与地域分布特征。结果显示,中国潜在颠覆性低碳技术专利共计306件,约占申请总量的千分之一;此类技术专利主要集中于建筑业、污染处理、产品生产、交通、能源等5个与经济社会发展高度相关领域,而在温室气体处理这一高技术领域则存在明显短板;地域上约60%颠覆性技术专利产生于北京、江苏、广东、山东、上海等5个东部省市,且呈现出较其他一般专利更为集聚的特征。

Disruptive low-carbon technological innovation is an important means to further implement the in-novative driven development and promote the low-carbon transformation of the whole society. Based on the CPC-Y02 classification jointly published by EPO and USPTO, the POT model is used for the first time to analyze forward citation number of 264,444 low-carbon patents in 6 fields and the potential disruptive low-carbon technology in China from 2004 to 2013. Furthermore, the regional distribution characteristics of patents are analyzed. The results showed that 306 potential disruptive low-carbon technologies are selected, accounting for about 1/1000 of the total low-carbon patent applications. At present, these patents are mainly concentrated in the areas of construction, commodity production, transportation, energy and so on, highly related to economic development in China. But there are obvious shortages in the high-tech domain of greenhouse gas treatment. These patents geographically concentrate on 5 eastern provinces and cities, including Beijing, Jiangsu, Guangdong, Shandong and Shanghai, and show a more concentrated feature than other general patents.
