Introduction   The current distribution quota system is mainly used in the feasibility study of the distribution network project to the construction of the construction cost of the construction drawing design phase. The essence of the distribution quota system is the valuation model of "quantity and price integration" ; the integrated unit price of the distribution network bill of quantities is still fixed. The pricing method determines that, in essence, the fixed pricing model is still used, and the pricing of the distribution list has not yet reached a mature market environment. In order to adapt to the characteristics of the socialist market economy in the new era, promote the orderly competition and healthy development of the power grid engineering construction market, promote the transformation of the management functions of the engineering cost industry, meet the needs of the entire process of cost data management, and increase the participation of all parties involved in the international construction. The ability to compete and optimize and improve the current pricing system for distribution network projects is necessary and urgent.

    Method   This paper summarized the applicability and limitations of the current distribution network engineering pricing system and combines with the current distribution network cost management and market economy development needs to explore and try to optimize the structure of the distribution network pricing system.

    Result   After comparison and optimization of distribution network cost, the optimized pricing system structure is more in line with the needs of current market economy development.

    Conclusion   This work provides some guidance for further study on the optimization of distribution network engineering.
