Climate policy and China's external balances

To explore the impact of the China Carbon Emissions Trading Exchange (CCETE) on international trade and capital flow, we develop a two-country dynamic general equilibrium model with asymmetric climate policies. We use targets of decreasing carbon emissions intensity to simulate the strengthening of the CCETE policy. We find that the strengthening of climate policy improves China's trade balance and current account. We also find that output and carbon emissions of the rest of the world with a less stringent climate policy increase (known as carbon leakage) in the short run, but decrease (known as positive externalities of climate policy) in the long run. These findings suggest that China could benefit from more stringent climate policy due to the improvement of its external balances, and the world could also benefit due to the mitigation of climate change . • This paper explores impact of the China Carbon Emissions Trading Exchange (CCETE) on international trade and capital flow. • Targets of decreasing carbon emissions intensity is used to simulate the strengthening of the CCETE policy. • Strengthening the climate policy is found to improve China's trade balance and current account. • Output and carbon emissions of the rest of the world increase in the short run, but decrease in the long run.
