The second credit value for the carbon ordering party may be determined by the following formula:
βn=[J×d+βn-1]/2，J=0.2,0.4,0.6,0.8,1
Wherein, beta n represents the credit value of the carbon purchasing party after the nth transaction, J represents the evaluation value of the carbon purchasing party, and different evaluation grades have different values. When beta n-1 is used to represent a first credit value for a carbon buyer, beta n may represent a second credit value for a carbon seller.
S4-B-2: and if the second credit value of the carbon purchasing party is lower than the second credit value threshold value, prohibiting the carbon purchasing party from carrying out the carbon transaction after the carbon transaction is completed.
The second credit threshold is the lowest credit value of the carbon purchasing enterprise for carrying out the transaction on the carbon transaction platform, and when the second credit value of the carbon purchasing party is lower than the second credit threshold, the carbon transaction platform can prohibit the carbon purchasing party from carrying out the carbon transaction.
In this embodiment, the credit value of the carbon purchasing party after the carbon transaction is performed may be adjusted according to the evaluation level of the carbon purchasing party. And when the credit value of the carbon purchasing party is too low, namely when the second credit value of the carbon selling party is lower than the second credit value threshold, prohibiting the carbon purchasing party from carrying out carbon transaction, and ensuring the transaction credit environment of the carbon transaction.
