The Visualization Analysis on Present Research Situation and Trend of Tackling Overcapacity of Energy

As the pillar industry in the national economy, energy is facing a serious problem of overcapacity. Therefore the visualization study is demonstrated to more clearly understand the situation of tackling overcapacity of energy. The data source is based on the 4527 articles included in China National Knowledge Infrastructure database from 2000 to 2016, whose topics are all tackling overcapacity of energy. The tool SATI for statistical analysis of articles information is used to have frequency statistics of keyword and literature source, and to generate keywords co-occurrence matrix. Then the softwares of Ucinet and Netdraw are utilized to further draw the keyword co-occurrence of knowledge mapping for articles visualization, and to analyze the hotspots and tendencies in the area of tackling overcapacity of energy. From the research trend, tackling overcapacity of energy will be the hotspot for a period in the future. The paper is expected to provide the corresponding theoretical reference for the researchers in the field of tackling overcapacity of energy.
