The invention relates to a heat bridge dispersive built-in heat insulation concrete structural system. The system comprises a bearing concrete structural layer, a heat insulation material layer and a concrete protective layer from the inside to the outside; reserved holes are formed at regular intervals along the longitudinal and transverse directions of the heat insulation material layer; transverse steel bars in the holes are connected with steel bars in the bearing concrete structural layer and the concrete protective layer, and the steel bars and the cast concrete form a tension bridge; and an inner heat insulation material layer which is slightly greater than the reserved hole is fixed inside the bearing concrete structural layer corresponding to the reserved hole. The system can disperse heat bridge effect, balance heat transfer of a building envelope structure and remarkably reduce the heat bridge effect, and has good heat insulation performance; the built-in heat insulation layer of the system is safe
