It took iFLYTEK and Neusoft as the research objects to explore the inherent mechanism of smart solution development through building digital capabilities. When developing smart solutions， enterprises face dual pressures from both demand and technology dimensions. In this situation， enterprises follow a demand-oriented cognitive and technology-oriented design logic of action to build digital capabilities to promote the development of smart solutions. The development process of smart solutions based on digital capabilities is characterized by differences driven by technology and business needs. The development mechanism is refined into the tandem complementary and the parallel orchestration mechanism to build the required digital capabilities . The former emphasizes the cooperative and complementary relationship of “lips and teeth”， and is realized through behaviors of unique complementarity and enhanced complementarity . The latter emphasizes the connection and interaction of “echoing each other” between the core enterprises and the participating subjects， and is realized through interactive and integrated orchestration behaviors. The findings supplements the theoretical gap caused by the insufficient exploration of smart solution development in previous studies， and contributes to the continuous deepening of the understanding of digital innovation implementation path by refining the internal logic of enterprises’ smart solution development through building digital capabilities.
