The Impact of Exchange Rate on China’s Carbon Price: From the Perspective of Regional Differences
Wang Qian & Lu Jingjing (Jilin University)
Abstract:Exchange rate impacts carbon price by changing energy relative price,import and export.Carbon pricing not only affects low carbon transition but also influences abatement cost and development rights of emitters.In the context of speeding up of financial market’s opening up and the increasing of exchange rate volatility,the impact of foreign exchange market on carbon is a key factor for the success of the national unified carbon market and the regional balance development in mitigation.Based on an EGARCH-Copula model,we find the impacts of RMB exchange rates on the carbon prices of six pilot carbon markets in China has significant regional differences.The impact on the carbon prices in Tianjin is negative,but positive in the other five carbon markets; RMB exchange rate has a strong impact on the carbon prices in Beijing,Shanghai and Shenzhen,but weak in Tianjin,Hubei and Guangdong;RMB exchange rate has strong upper tail correlation with the carbon prices in Beijing and Shanghai,but strong lower tail correlation with the carbon prices in Guangdong.Therefore,the design of the national unified carbon market should take regional differences into account; establish a response mechanism and improve the carbon price management by considering the regional heterogeneity of external impacts of exchange rate market on carbon market, and strengthen the role of RMB in energy pricing and promote the carbon financial innovation.
