Abstract: The 14th Five Year Plan points out to “accelerate the development of services such as research and development design, industrial design, inspection and testing certification”, and “to build an innovation and service complex to form an emerging industry growth engine with complementary advantages and reasonable structure”. It can be seen that building a service chain that matches the industrial innovation chain and driving the fusion of innovation chain and service chain (dual-chain) in emerging industries is crucial for facilitating efficient matching between innovation demands and service supplies and enhancing industrial innovation capability. Digitalization propels changes in dual-chain entities and diversifies the dual-chain fusion models, accelerating the dual-chain fusion process and presenting new evolutionary characteristics and structures. Drawing on the 6C theoretical framework and using the new energy vehicle industry as a vertical case study, this study explores the dual-chain fusion mechanism in emerging industries driven by digitalization. The findings show that the process of dual chain fusion in emerging industries follows a causal logic of external context (driven by digitalization) - fusion behavior (structural adaptability adjustment, supply-demand relationship connection, flexible functional configuration) - fusion result (improvement of industrial innovation capability). The dual-chain fusion has gone through three evolution stages of “fusion exploration→fusion interaction→fusion upgrading” (Change). The dominant elements and combination modes of digital driven context in the three stages of fusion are different, presenting an evolutionary feature of “guided→interactive→pioneering” (Context). Under the drive of digitalization, the dual chain entities undergo strategic updates and sequentially carry out structural adjustments of “digital shaping chain→digital strengthening chain→digital expansion chain” (Construct). As an important support and promotion condition for fusion behavior, it guides the formation and reshaping of the “complementary efficiency cross-border” relationship connection mode (Cooperation). With the evolution of linkage modes, the types and goals of cooperation between dual chain entities have dynamically changed, resulting in the formation of a “single point→modular→ecological” functional configuration for dual chain fusion (Configuration). This not only supports the strategic progression of dual chain entities, but also provides timely feedback for relationship linkage, promoting the optimization of chain network structure. In the continuous deepening of dual chain fusion, emerging industries have successively formed digital driven distributed, fused, and cross-border innovation capabilities (capability), promoting the upgrading of the dual chain fusion network to an ecosystem of “innovation service” cross-border docking and intelligent collaboration, and accelerating the development of new quality productivity. This study uncovers the black box of digital-driving mechanisms and process of dual-chain fusion in emerging industries, to make up for the shortcomings of existing research in exploring the mechanism of dual chain fusion from a static perspective, and the 6C theory is combined with the multi-agent, multi interaction, and multi-stage evolution characteristics of complex systems, providing a suitable framework and inspiration for the evolution research of more types of complex systems in the future. and also provides insights for the strategic planning of dual-chain fusion in industries and the cooperative practices of dual-chain entities.
