Its dimension is u×1. '1' means that the unit needs to be modified in that year, and '0' means that the unit does not need to be modified in that year. If all elements of are 0, then regenerate Otherwise, continue the calculation. The unit with the number '1' in the corresponding technology application matrix M12 initial,y Randomly select one '0' and convert it to '1' to obtain the temporary technology application matrix For the rows where all technical transformations are completed (i.e., rows where all technologies have been applied, all elements in the row are '1'), skip the row and continue to transform other rows. In this way, the first temporary technical transformation matrix can be obtained.

If the carbon reduction potential value after the second technological transformation is completed is less than the industry carbon emission gap value in the target year, this indicates that the current carbon emissions do not meet the standards. At this time, it is necessary to restart the process of "determining the second temporary technological transformation matrix based on the initial technological matrix" to explore a better technological transformation plan. If the carbon reduction potential value after the second technological transformation is completed is greater than or equal to the industry carbon emission gap value in the target year, it means that the carbon emissions meet the standards. In this case, the total investment and operating costs required for the second technological transformation are accurately calculated based on the second temporary technological transformation matrix. Then, based on the total investment and operating costs required for the second technological transformation and the carbon reduction potential value after the second technological transformation is completed, a specific algorithm is used to determine the second emission reduction cost.
