煤炭企业专利技术研发热点与前沿的可视化分析 ——以中国神华为例

随着煤炭开采面临环境污染与资源枯竭的双重挑战形势日益严峻,以专利为表征的技术进步将在煤炭企业的创新发展中扮演重要角色。文章以中国神华能源股份有限公司收录在德温特世界专利索引数据库中2004-2018年间的专利为数据源,在对其专利数量、类型、技术生命周期进行基本统计分析后,运用CiteSpace着重对研发热点与前沿进行了可视化研究。结果发现,中国神华专利数量在15年间快速攀升并长期处于技术发展期,但其发明专利占比相对偏低。通过聚类分析和词频探测识别出专利研发的热点为计算与控制、废水废气处理等技术领域,预测未来几年中国神华专利研发重点仍在数字计算机领域,将不断提高设备的智能化程度。这将为中国神华乃至全国煤炭行业明确专利技术研发方向提供一定的参考价值。

Visualization Analysis of the Hot Spots and Frontier in the Field of Coal Enterprises" Patents Technology :Taking the Case of China Shenhua Energy Company Limited

With the coal mining facing the dual challenges of environmental pollution and resource exhaustion, the technological progress represented by patent will play an important role in the innovative development of coal enterprises. This paper takes the patents of China Shenhua Energy Company Limited(CSEC) from 2004 to 2018 in the World Patent Index database of Derwent as the data source. After the basic statistical analysis of the number, type and technology life cycle of the patents, the visualization research of research hotspots and frontiers is carried out with CiteSpace. The results show that the number of patents of CSEC has been rising rapidly in the past 15 years and is in the stage of technology development for a long time. But the proportion of invention patents is relatively low. Through cluster analysis and word frequency detection, the hot spots of patent research and development are identified as computing and control, waste water and waste gas treatment and other technical fields. It is predicted that CSEC"s patent research and development in the next few years will still focus on the digital computer field, and constantly improve the degree of intelligence of equipment. This will provide reference value for CESC and even the whole coal enterprises to clarify the direction of patent technology.
