Study on the System Dynamics Model of Low Carbon City Development

Low-carbon economy has received extensive attention from all walks of life, as a new change of human economic development mode.In order to promote the sustainable development of the future society, economy, energy and environment, this paper designs a system dynamics model for the development of low carbon cities based on the urban low carbon economic indicators.Vensim software is adopted to test the system dynamics model, through the calculation of relative error between actual value and simulation value, and the model can be considered to be effective.Combined with the development of low carbon economy in Nanjing in the next 5 years, the development of low carbon economy in the city is simulated, and the feasible path of low carbon city construction is obtained.
