Introduction  The proposal of the "dual carbon" strategy has given new requirements and connotations to the reduction of energy consumption intensity and the "dual control" of the total amount. On the premise of adhering to the priority of energy efficiency, we should fully consider the stage of regional development and reasonably ensure the "dual control" indicators are decomposed and implemented layer by layer.

  Method  Taking the decomposition of the "dual control" indicators of energy consumption in the "14th Five-Year Plan" of a certain city as an example, this paper selected quantifications that could reflect the economic level, energy consumption volume, energy-saving potential and the completion of the energy-saving goals of the "13th Five-Year Plan" indicators of each district and county (city) and built a combined weighting assignment model based on the combination of hierarchical analysis and objective weighting to calculate the weight of each indicator, obtaining the "dual control" indicator distribution results, and then used clustering analysis to carry out the differentiation of the indicator system and cluster aggregation.

  Result  By comparing the results of combination weighting and clustering analysis, the regional energy consumption intensity reduction target decomposition algorithm based on multi-indicator combination weighting and clustering analysis can obtain basically consistent results.

  Conclusion  Based on the results of the above two methods, the actual economic development and government management needs, the energy consumption management targets of different levels are obtained, which takes into account regional development differences, conforms to the national "14th Five-Year Plan" energy consumption "dual control" system requirements and decomposition principle, and has the characteristics of replicability and promotion.
