绿色技术创新是实现绿色发展和碳中和的关键驱动力,正成为全球新一轮工业革命和科技竞争的重要新兴领域。本文调研梳理了主要国家和地区发布的促进绿色技术创新的战略规划,并基于全球绿色技术领域PCT专利的计量和文本聚类方法,分析了国际绿色技术的研发态势。结果表明,全球主要国家十分重视绿色技术战略布局,在工业、能源、交通等多个领域提出研发和应用推广规划。当前主要的发展趋势是降低关键绿色技术成本和进一步推动规模化应用。从专利分析结果看,2000年以来,全球绿色技术研发经历了快速增长、缓慢衰退和回升三个阶段;从技术领域看,能源领域是绿色技术研究最多的领域,专利数量占比达30.4%;美日德在绿色技术领域的研发处于领先地位,是绿色技术PCT专利主要技术来源国,中国绿色技术PCT专利申请数量虽然在不断增加,但仍与领先国家存在一定差距。对此,本文提出三点建议: 1)抓住全球绿色复苏大趋势,完善绿色技术发展配套政策,进一步加强宏观布局和系统谋划,使之成为新的经济增长点; 2)促进绿色技术在工业、交通、建筑、农业等多领域的发展和推广应用; 3)加快构建可再生能源、氢能等多元清洁低碳能源体系,全面推进能源转型。 |

Green technology innovation is a key driving force for achieving green development and carbon neutrality, and it is becoming an important emerging field in the new round of global industrial revolution and technological competition. This paper investigates the strategic layout of promoting the development of green technologies recently released by major countries and regions, and analyzes the development trend of international green technology by using patent measurement and text clustering based on PCT patents. The results show that major countries in the world have attached great importance to the strategic layout of green technologies,and proposed R&D and application promotion plans in industries,energy, transportation and other fields. The current main trend is to reduce the cost of key green technologies and further promote large-scale applications. According to the results of patent analysis,since 2000,global green technology research and development had experienced three stages: rapid growth, slow decline,and rebound. From the perspective of technology, green technology in the energy field is the most studied area,with patents accounting for 30.4%. The United States, Japan and Germany are leading the field of green technologies research, and are the main green technology PCT patents application countries. Although the number of PCT patent applications of green technology in China is increasing, there is still a gap between China and the leading countries. Based on the analysis, this paper puts forward three suggestions: 1) grasp the global trend of green recovery, improve the green technology development supporting policies,and strengthen the top-level design to make it a new economic growth point; 2 ) promote the development and application of green technology in industry, transportation,construction,agriculture and other fields; 3) accelerate the establishment of renewable energy, hydrogen and other clean low-carbon energy system, and comprehensively promote energy transformation. |
