The traditional chemical industry brings the environment pollution has been very serious, hazardous waste are produced worldwide each year up to 3-4 Million tons, this situation only cause harm to the environment, but also threaten the survival of mankind. Technical innovation is an effective solution to this problem,first of all, we construct the endogenous economic growth model to analyze the low-carbon economic growth, from the results we can get that: if the technical innovation has a sufficiently high efficiency, economy can overcome the constraint of non-renewable energy consumption, achieve green chemistry and low-carbon economy growth. Therefore, technological innovation is the fundamental way to solve the problems of environment and resources, and also the essence to develop low-carbon economy. China should better use financial factors to promote the low-carbon economic growth and change the economic growth model
