摘要:
“开展种源‘卡脖子’技术攻关,打好种业翻身仗”亟需探明当前粮食作物生物育种技术领域的专利创新布局和竞争态势。依据专利导向的产业竞争情报分析框架,以核心专利数据(不包含中国港澳台地区)为基础,从整体环境、技术布局和机构竞争3个方面剖析了粮食作物生物育种技术领域的全球创新布局及竞争态势。结果表明,领域内技术创新活跃,中国核心专利量位居前列,但与美国相比有很大差距;北美、欧洲和中国是全球主要技术布局地,尤以美国最为集中,中国发明的专利主要布局在国内,全球竞争能力不足;基因组重测序技术、分子标记辅助育种、抗性技术和杂交技术等是领域热点技术;突变或遗传工程、改良基因型的方法是领域内“主导-成熟型”技术,各主要国家和地区均进行了重点布局,我国在“新兴-成长型”技术领域具备相对优势;跨国种子公司的技术和市场竞争覆盖了全球主要国家和地区,技术布局主题广泛,因此,我国亟待培育有国际竞争力的本土创新研发机构。上述结果为政府及科研部门制定该领域技术创新引导政策,以及开展前瞻性研发布局和优化竞争决策提供参考。
