Abstract:  A clarification of “impact mechanism for directed technological change on green growth under pollution control” can provide reference for different economic systems in the world to implement a new and more sustainable green growth reform. Based on re-distinguishing the forms of directed technological change and re-constructing the endogenous relationship between non-renewable resource and directed technological innovation, this paper propose a non-linear optimal control model in which both the objective function and the possible constraints can fully embody the characteristics of inclusive, sustainable and equilibrium in green growth. Findings will be summarized from the results of the steady state calculation in the infinite horizon problem and the model simulation. Firstly, the key dynamic element of green growth is technological innovation and the capital space of which should be adequate. Secondly, non-renewable resource is not necessary to drive green growth. Finally, environmental policies should be implemented to guide the carbon abatement technology rather than the production technology.
