Carbon emissions cap or energy technology subsidies? Exploring the carbon reduction policy based on a multi-technology sectoral DSGE model

J. Gu, Y. Li, et al.

This research conducted by Jianping Gu, Yi Li, Jingke Hong, and Lu Wang delves into the effectiveness of various carbon reduction policies in China. By employing a dynamic stochastic general equilibrium model, the study uncovers compelling insights indicating that subsidy policies may lead to more effective long-term emission reductions compared to carbon caps, with fossil fuel subsidies demonstrating noteworthy cost-efficiency.

Abstract
This paper investigates the effectiveness of different carbon reduction policies in China using a multi-technology sectoral dynamic stochastic general equilibrium (DSGE) model. The study compares a carbon emission cap policy with fossil fuel and renewable energy technology subsidy policies. Findings suggest that subsidy policies are more effective for long-term emission reduction, with fossil fuel subsidies proving more cost-efficient. The paper also analyzes the impact of various economic shocks on macroeconomic growth and pollutant emissions under each policy scenario.
