Firstly, the stationarity and cointegration of the selected futures price series were verified by ADF test and PP test. Then, the Gaussian Copula, t-Copula, and Clayton Copula models were used to model and analyze the correlation between carbon market and energy futures market. The results show that there is a strong correlation between carbon market and energy futures market, and different Copula functions explain the correlation differently, but overall, it shows a high correlation. In addition, the joint distribution established by the Copula model was simulated, and the future market price changes were predicted, in order to provide some advice for investors.Key words: Copula model; correlation; carbon market; energy futures market; predictio。
The results of the study highlight the significant correlation between the carbon market and energy futures market. The use of Copula models was found to be effective in explaining the nature of this correlation. The different Copula functions used in the study, such as Gaussian, Clayton and Gumbel, provided different insights into the relationship between the two markets. However, the overall conclusion was that there is a high positive correlation between the carbon market and energy futures market.The Copula model was also used to simulate the joint distribution of the two markets. This allowed for the prediction of future market price changes. This prediction can be useful for investors who want to make informed decisions regarding their investments in these markets. For instance, the study found that a significant portion of the carbon market price changes can be attributed to changes in the energy futures market. Therefore, investors in the carbon market should also closely monitor the energy futures market.In conclusion, this study provides evidence of a strong correlation between the carbon market and energy futures market. The use of Copula models is an effective way to explain this correlation and predict future market price changes. Investors can use these findings to make informed investment decisions in these markets。
Moreover, the findings of this study also have important implications for policy makers. The carbon market plays a crucial role in achieving greenhouse gas emission reductions required to mitigate climate change. Therefore, policy makers should recognize the impact of energy futures market on the carbon market and incorporate it into their decision making.One way to do this is by implementing policies that promote investment in renewable energy sources. As renewable energy sources become more prevalent and affordable, the demand for fossil fuels decreases, leading to lower prices in the energy futures market. This, in turn, could lead to lower prices in the carbon market, making it less attractive for investors. By promoting renewable energy, policy makers can help reduce the impact of energy futures market fluctuations on the carbon market.Another way to address this issue is by promoting market stability. Fluctuations in the energy futures market and their impact on the carbon market can lead to volatility and uncertainty, which can discourage investment. By implementing policies that promote transparency, reduce information asymmetry, and increase market liquidity, policy makers can help stabilize the market and make it more attractive to investors.In conclusion, this study provides evidence of a strong correlation between the carbon market and energy futures market. Investors and policy makers should recognize this correlation and its implications for their decision making. By using Copula models, investors can better predict market price changes and make informed investment decisions. Policy makers can also use these findings to implement policies that promote market stability and encourage investment in renewable energy sources。
Furthermore, this study also sheds light on the importance of incorporating ESG (Environmental, Social and Governance) factors in investment decisions. With the increasing recognition of the impact of climate change, investors are increasingly considering a company's ESG performance before investing. This study highlights the correlation between carbon emissions and energy prices, and its implications for both the environment and the economy. Therefore。
