Prediction method of carbon emission trading price based on claim rights

Predicting carbon emissions trading prices is of great significance for improving market transparency. Therefore, this paper proposes a carbon emissions trading price prediction method based on claim rights. Firstly, a factor analysis model to determine six factors that affect the price of carbon emission rights is constructed, including the ratio of industrial added value, coal price, maximum temperature, closing price, natural gas closing price, and policy. Then, a transfer rate matrix is constructed based on Markov functions, and a carbon emission rights option price prediction model is constructed using claim rights. Finally, the influence parameters are substituted into the prediction model, and the European call option method is used to determine the equivalent consideration expectations, achieving the transaction price solution. The results show that the prediction error of this method is only +0.0014 yuan/ton, with an accuracy of 96%, indicating that this method can improve the prediction effect of transaction prices.
