专利视角下全球可控核聚变行业发展态势研究
Research on the Development Trend of Global Controlled Nuclear Fusion Industry from the Perspective of Patents
摘要
Abstract
Based on three decades of global patent data,This study conducts a systematic analysis of the controlled nuclear fusion industry from the dimensions of temporal evolution,geographical distribution,innovation entities,and technological composition.It reveals that the global controlled nuclear fusion industry is in its early growth stage,with no stable competitive landscape yet established,though showing signs of transitioning toward a mid-growth phase.Fluctuations in patent concentration indicate the industry is undergoing a new round of technological transformation.In the competitive landscape,a tripartite structure has formed among China,the United States,and Japan.China,despite its late start,has achieved rapid catch-up growth,leading globally in total patent volume.Its market size exceeds the combined total of Japan and the United States,with Chinese innovation entities accounting for approximately 42%of the global total.However,significant shortcomings remain:99%of China's patents are concentrated in the domestic market,while U.S.companies dominate the majority of high-value patents.The technological development follows a pattern of"thermonuclear fusion leadership with diversified technological coordination."Research hotspots focus on core systems such as stellarators,blankets,and vacuum vessels,while non-resonant and high-harmonic technologies represent potential future directions.Based on these findings,this study recommends that China implement a strategy of"quality enhancement,global patent protection,diversified collaboration,and international competition-cooperation"to transform its quantitative patent advantage into industrial core competitiveness.关键词
