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.

Taking the Derwent Innovations Index database as the data source, selecting China, the United States, Japan, South Korea and Germany as the comparative research objects, this paper analyzes the overall trend of image understanding technology in the five countries by patent metrology, and adopts the technology competitiveness model to evaluate the technical competitiveness of the five countries. The results show that China is far ahead in the number of patent applications, but the average cited frequency of patents is far lower than those of the United States and Japan. At the same time, the United States almost occupies all the highly cited patents of image understanding technology. Owing to a large number of image understanding technology patents, China's technical strength is slightly ahead of the United States, becoming the first. However, the technology impact index of China is below the expected value, far lower than those of the United States and Japan. The results indicate that China possesses plenty of image understanding technologies which commonly lack of influence. Overall, Japan, South Korea and Germany fall behind China and the United States in terms of technical strength, but each has its own advantages in a certain sub technical field. Japan's technology impact index of scene recovery technology is far higher than those of China, South Korea and Germany. South Korea's image perception and interpretation technology patents account for a large proportion in the world; Germany's technology impact index and patent sharing index of spatiotemporal technology are at the top level in the world. To enhance China's international competitiveness in the field of image understanding technology, it is suggested that China should promote the in-depth development of image understanding technology, promote the balanced development of various sub technologies in the field of image understanding technology, strengthen international cooperation in the field of image understanding technology, and innovate the government service system, so as to create a good environment for technology development.
