Abstract: One major outcome of digital economic development is the emergence of a digital adjustment mechanism. This mechanism has gradually permeated corporate investment and business operations while remaining inherently a market mechanism. From an economic perspective, it is essential to analyze its formation process and market effects on the basis of clarifying its connotation and extension. The core research questions are as follows:What underpins the formation and expansion of the digital adjustment mechanism? To what extent and in what scope can the application of Artificial General Intelligence (AGI) expand such a mechanism? What correlations exist among the digital adjustment mechanism, AGI technology spillovers, and corporate investment and operation? By what means does the digital adjustment mechanism change the inherent content of market mechanisms? What influences will AGI technology spillovers exert on the efficiency of corporate production and operation, and in what respects can such influences provide a theoretical foundation for the development of digital economics? Can economics treat the digital adjustment mechanism as the 'invisible hand' that guides the operation of the digital economy, and explore how AGI technology spillovers promote the integration of the mechanism into market mechanisms?With the rapid progress of AGI machine learning and artificial neural network technologies, economic research should focus on the evolution of AGI technological levels, so as to clarify and verify the impacts of the digital adjustment mechanism on corporate investment and business activities. Economic studies on digital adjustment mechanisms in the context of AGI technology application can offer a theoretical analytical perspective for constructing the theoretical system of digital economics.
