Abstract: New quality productivity is green productivity. Therefore, as a key deployment to accelerate the national green energy transformation, the dual carbon strategy and new quality productivity have a significant coupling and symbiotic relationship. The development of new quality productivity explores new space for core technologies’ green innovation of dual carbon strategy, and the implementation of dual carbon strategy creates a new foundation of the green economic policy system for new quality productivity. By deconstructing the symbiotic unit, symbiotic mode, symbiotic interface and symbiotic environment, this paper put forward the symbiotic path of dual carbon strategy and new quality productivity from four dimensions: aggregating the symbiotic unit and stimulating the deep participation motivation of multiple actors; creating the symbiotic mode and promoting the reciprocity between dual carbon strategy and new quality productivity; strengthening the symbiotic interface and opening the transmission and synergy channel between green and low-carbon development and new quality productivity; creating the symbiotic environment and building the institutional advantages of green economic policy system, so as to promote both the dual carbon strategy and the systematic improvement of productivity.
