Forecast and Analysis of Renewable Energy Technology Development Trend Based on Knowledge Graph and Patent Data

Abstract

The development and utilization of renewable energy is an important part of national strategy. In this study, Cite Space was used to analyze the Knowledge Graph of relevant research literature and define the research hotspots and the key technologies in the field of renewable energy. Then, the domestic and foreign related patent data in the field of renewable energy were retrieved through the database of Wanfang, and Logistic model was used to make a comparative analysis of the life cycle of relevant technologies in this field, so as to predict the current development stage and future development trend of China's renewable energy technology.
