With the competition of Chinese enterprises shifting from scale orientation to high-quality orientation, it is critical to enhance the level of business-finance integration. In practice, many enterprises lack the conceptual understanding of business-finance integration as well as the support of research method, which leads to the difficulty of implementing business-finance integration. This study attempts to establish the model of relationships between business-finance integration and enterprise value, analyze which process factors are worth paying attention to, and help enterprises improve the level of business-finance integration in both theory and practice.This study uses the research methods of case and empirical analysis to draw four main conclusions: (1) business-finance integration can facilitate the realization of enterprise value directly because business development has a stronger sense of purpose under the guidance of financial indicators, and financial resources are effectively allocated based on business needs; (2) business-finance integration can facilitate the realization of enterprise value through internal operations because the efficiency of operation process is increased, customer satisfaction is enhanced, and ultimately financial performance is improved; (3) business-finance integration can facilitate the realization of enterprise value through the upgrade of organizational capacity, because the internal communication, work ideology, and operational platforms are more aligned in the organization, and the enterprise value is realized under the liberation of organizational capacity; and (4) digitalization level can facilitate the integration of business and finance to play a greater role, because digitalization makes operation and management more efficient and stable. The innovation of this study is reflected in two aspects: (1) based on the mechanism of value transmission, the model of business-finance integration and enterprise value creation is established, which enriches the theory of business-finance integration; and (2) the identification of the logical relationships among business-finance integration, operation, organization, value realization, and digitization provides a decision-making framework and basis for industry-finance integration.
