中国油气产业专利发展态势分析

Analysis on the Development Trend of Patents in China Oil & Gas Industry

摘要:

油气产业的发展与其科技发展水平有着很强的关联性,专利信息是体现技术进步的重要指标。通过分析我国油气产业专利发展态势,可对产业技术的发展进行深入的了解。本文使用Derwent Innovation数据库,改进DWPI手工代码分类方法,对中国油气产业进行专利分布结构分析,专利申请趋势分析及未来专利发展预测。结果显示,近年来由于行业主营业务收入下降,油气勘探与开采业和油气加工行业各技术领域的年专利申请量呈下降趋势。国内储运业务的快速发展使得油气储运行业专利的未来发展趋势较好。

Abstract:

There is a strong connection between the development of oil gas industry and the industry’s technology development. Patent information is an important measure of technological trends. Therefore, we can have an in-depth understanding of the development of China’s oil gas industry technology through the analysis of the current situation of China’s oil gas industry patent development. By using Derwent Innovation Patent Database and an improved DWPI manual code classification, we applied the methods of patent distribution structure, patent application trends and future patent development forecast to analyze the oil gas industry’s patents. In recent years, owing to the industry’s main business income decline, the number of annual patent applications shows a downward trend in oil gas exploration and mining industry, as well as in oil gas refining industry. With the rapid development of domestic storage and transportation business, the development trend of oil gas storage and transportation industry patents is promising.
