This paper proposes the Gravitational Virtual Particle Realization Field Theory, which attributes the gravitational interaction to the synergistic effect of the realization and transmission of virtual gravitons in the vacuum and the spacetime structure. The theory is based on the most primitive and essential definitions of physics: the change in momentum equals the product of force and action time, and the change in energy equals the product of force and action distance, which fundamentally ensures the self-consistency of momentum and energy transmission. This paper assumes that the propagation and interaction laws of gravitons are completely equivalent to those of photons: when an object is at rest, gravitons are mainly reflected and can transfer nearly double the momentum; when an object moves at a high speed close to the speed of light, the absorption ratio of gravitons increases significantly and the reflection ratio decreases, the momentum transfer no longer exhibits the double characteristic, and the reflection and absorption ratios change continuously with the moving speed of the object, thus realizing a physical picture consistent with reality both quantitatively and qualitatively. This theory does not presuppose the objective and real existence of gravitons: gravitons can be understood as real particles, or as dense regions of energy fluctuations in the gravitational field. Regardless of the existence of their ontology, the model is completely self-consistent in both mathematical and physical logic. The theory can naturally eliminate ultraviolet divergence, quantitatively derive the gravitational constant G from the perspective of micro-interactions, be compatible with Newtonian gravity, special relativity and general relativity, and realize the underlying unification of gravitational and electromagnetic interactions, thus forming a complete, closed and quantitatively testable quantum gravity framework.
