New technologies such as digital twin and big data etc., have triggered people's new thinking on manufacturing mode. Therefore, this paper proposes a new model of big data manufacturing services driven by digital twin, combining with the important content of manufacturing services in the "Made in China 2025" plan. First of all, the research progress of intelligent manufacturing, digital twin and manufacturing service mode at home and abroad is reviewed. Secondly, an open architecture and operation logic of big data manufacturing mode driven by digital twin is proposed. Thirdly, the enabling technology of big data manufacturing service mode is studied from three aspects: the two world driven by digital twin and its description, the combination of digital twin and big data, and the model establishment and optimization of big data manufacturing service mode. This new manufacturing service model has theoretical and practical significance for promoting the transformation and upgrading of traditional manufacturing enterprises and promoting the comprehensive competitiveness in the new international competitive environment.
