The research and development, promotion, and application of advanced green and low-carbon technologies are crucial in promoting the timely achievement of carbon peak and carbon neutrality goals. In order to further promote green and low-carbon technological innovation and industrial transformation, and cultivate and strengthen new driving forces for green and low-carbon development, recently, the National Development and Reform Commission and other departments jointly issued the "Implementation Plan for Green and low-carbon Advanced Technology Demonstration Project" (hereinafter referred to as the "Plan"), proposing the overall idea, main goals, key directions, and guarantee measures for carrying out green and low-carbon advanced technology demonstration. Data shows that from 2016 to 2022, the total number of global green and low-carbon technology invention patents authorized reached 558000, of which 178000 were granted to Chinese patent holders, accounting for 31.9%, with an average annual growth rate of 12.5%, significantly higher than the overall global level of 2.5%. China has become an important contributor to global green and low-carbon technology innovation. The demonstration of green and low-carbon advanced technologies is of great significance, as it plays an important role in accelerating the application and promotion of green and low-carbon advanced applicable technologies, improving the policy environment for supporting the development of new industries and formats, and promoting the formation of new competitive advantages in related industries. "Ren Xianguang, director of the National Energy Conservation Center, analyzed that the significance of the" Plan "introduced this time mainly includes the following three points: firstly, the implementation of the green and low-carbon advanced technology demonstration project is to implement the Central Committee of the Communist Party of China Important measures taken by the State Council for decision-making and deployment. The second is to carry out demonstration of green and low-carbon advanced technologies, which is a powerful means to break through the bottleneck of the industrialization application of advanced technologies. The demonstration of green and low-carbon advanced technologies is a key tactic for large-scale promotion and application. Ren Xianguang stated that the "Plan" clarifies the key directions for the demonstration of green and low-carbon advanced technologies, focuses on the forefront of green and low-carbon technology innovation, and includes advanced and applicable technologies that are basically mature but have not yet been commercialized in the key demonstration scope, providing a path for promoting market-oriented applications. The goal and task set in the "Plan" revolves around the carbon peak and carbon neutrality '1+N' policy system, which not only proposes technological demonstrations in the energy and industrial fields, but also includes technological demonstrations in the construction and transportation fields. It includes the demonstration and application of advanced and applicable technologies for carbon reduction at the source and in the process, as well as the demonstration of carbon sequestration technology at the end. The demonstration content basically covers various key areas of green and low-carbon industries. "Ren Xianguang analyzed. In addition, the "Plan" also specifies the guarantee measures for promoting the demonstration of green and low-carbon advanced technologies, and proposes specific work requirements. Ren Xianguang summarized the following four aspects: first, strengthening financial support. A sound financial incentive mechanism is a strong guarantee for promoting the implementation of technological demonstration. The plan proposes to strengthen departmental and local linkage, and comprehensively use investment, finance, and other methods to support the construction of demonstration projects. For demonstration projects belonging to fixed assets investment projects, actively support qualified demonstration projects by making overall use of the existing investment channels within the central budget, and include qualified green low-carbon advanced technology demonstration project infrastructure construction projects into the scope of local government special bond support. The second is to strengthen financial and tax policy support. Adhering to the combination of an effective market and a promising government, highlighting the dominant position of enterprises in technological innovation, can effectively guide various enterprises to actively participate in innovation and investment in green and low-carbon fields, and greatly stimulate market vitality and social creativity.
