Abstract: In order to investigate the impact of different policy options on the energy industry, based on the energy, economic, environmental, policy and social factors, based on the DPSIR theory, a simulation model of the energy industry development system from the perspective of low carbon economy is constructed. And taking Shaanxi Province as the research object, the model parameters and main equations are determined. The research results show that the extensive development of Shaanxi Province can still maintain a certain economic growth rate, but it has strong dependence on coal consumption and is obviously affected by resource constraints. The development of new energy industry has the most obvious effect on the environment. Taxation policies can be used to compensate for the cost difference between traditional and new energy sources, while economic and industrial policies have less impact.
