Abstract:Low carbon technology innovation and application are the essential guarantee for China to achieve a low carbon development path with Chinese characteristics. It is necessary to reasonably make planning of the roadmap of China’s low carbon technology development,which covers making clear the key technology fields,identifying development path of key technologies and the supportive policies required,exploring policies and measurements for technological innovation. As a whole,it is necessary by increasing national and local R&D investment to create perfect scientific and technological innovation system,and establishing the strategies such as putting enterprises/businesses at the position of the new main body,to further enhance China’s low carbon technology self-innovation ability. As for actual technologies,key low carbon technology of energy supply,transportation,building and industrial fields in China now are challenged by technological R&D,as well as cost or market. It is necessary to correctly identify technological characteristics,to formulate policies and measures suitable for development stage of technology in China today,and remove the key barriers for low carbon technology development by policy innovation.
