Theme Mining and Dynamic Evolution Analysis of Green and Low-Carbon Technology in China's Energy Industry Based on BERTopic Model
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 devel-opment 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.
