基于专利数据的风能核心技术识别及趋势分析*

Identification and Research of Core Technology in Wind Energy Based on Patent*

摘要:

[目的/意义]为识别风能领域的核心技术,探测风能领域的技术发展趋势,找出中国和发达国家在风能领域的技术差距,从而加速我国风能技术创新。[方法/过程]本文以中外专利数据库服务平台CNIPR作为数据源,利用社会网络分析方法对中国、美国和欧洲的共线网络图进行对比分析；然后将共线阈值和时间序列进行结合,划分四个阶段对中国、美国欧洲共线网络图进行对比分析。[结果/结论]识别出中国、美国和欧洲的核心专利领域,推测出中国风能领域未来的技术走向会集中在风能装置零件、部件和附件以及风能照明装置或系统两个方面,美国和欧洲则依然集中在风力发电机等核心领域。

Abstract:

[Purpose / Significance] The paper aims to identify the core technology and detect the development tendency in wind energy, finding the technological gap between China and developed countries to accelerate China"s wind energy technology innovation. [Method / Process] Taking patent database CNIPR as patent data source and using the social network analysis method, this paper takes a contrastive analysis with collinear network among China, America and Europe. Also, the paper combines threshold and time series, taking an analysis with the collinear network between China and Europe in four stages. [Result / Conclusion] Core technology of China, America and Europe are identified, and the paper predicts that the future technology of wind energy in China will focus on the parts and assemblies of wind energy device and lighting device, while America and Europe will still focus on the wind motor.
