摘　　要：能源行业绿色低碳转型是实现“双碳”目标的必然要求。依据技术生命周期理论研究中国能源行业绿色低碳技术发展阶段,采用BERTopic模型和余弦相似度计算方法对相关专利进行数据挖掘,分析各个发展阶段的技术主题、技术方向及动态演化规律。结果显示:中国能源行业绿色低碳技术的萌芽期、发展期和成熟期的主题数量分别为6个、12个和15个;萌芽期技术方向较为单一,发展期技术主题涵盖5个技术方向,成熟期涵盖4个技术方向;动态演化过程受到技术进步、政策导向等因素影响而体现出明显的时代特征。The green and low-carbon transformation of the energy industry is an inevitable requirement to achieve the goal of"double carbon".Based on the technology life cycle theory,this paper studied the development stage of green and low-carbon technologies in China's energy industry,adopted the BERTopic model and cosine similarity calculation method to conduct data mining of related patents,and analyzed the technical theme,technical direction and dynamic evolution law of each development stage.The results show that there are 6,12 and 15 topics in the germination,development and maturity stages of green low-carbon technologies in China's energy industry,respectively.The technical direction in the embryonic stage is relatively simple,the technical theme in the development stage covers 5 technical directions,and the mature stage covers 4 technical directions.The dynamic evolution process is influenced by technological progress,policy guidance and other factors,and reflects the obvious characteristics of the Times.

关 键 词：能源行业 绿色低碳技术 主题挖掘 动态演化 BERTopic模型
