Abstract: Solving the problem of climate change must depend on technology innovation. Technology innovation is seen not only as a technological problem, but also as an interaction course among science, engineering, economic factors and institutions. According to the framework of "technological regime" we can identify three types of innovations: incremental innovation, disruptive innovation and radical innovation. Radical innovation and part of disruptive innovation are locked-in to the hydrocarbon energy system, so adjustment of current policies is necessary. Obviously, governments including China's have begun to adopt new policy instruments due to the complexity of technology innovation.

Key words: technological regime, climate change, innovation, policy
