The carbon emission economic development level indicators of each region are constructed based on the regional GDP, and the carbon absorption ecological protection level indicators of each region are constructed based on the corrected carbon absorption numbers of each region. The output data module is responsible for determining the weight distribution of the carbon emission economic development level index and the carbon absorption ecological protection level index, and then calculating the balance between these two indicators. According to the preset division criteria of economic development and ecological protection balance, the specific carbon balance status of each region is output.
