The invention relates to an industrial capability docking technical method based on a
knowledge graph, and the method comprises the steps: obtaining a demand which comprises a category, a yield, a deadline, a
performance index, and a demand flow direction, wherein the demand flow direction is inflow or outflow, inflow is input from the target enterprise, and outflow is output to the target enterprise; determining sub-graphs meeting categories, yields, deadlines and performance indexes in the requirements from the
knowledge graph; determining a target enterprise from the sub-graph according to the demand flow direction in the demand; wherein the
knowledge graph comprises first-level points and second-level points, the first-level points are in one-to-one correspondence with the positions of the industrial chains, the second-level points are in one-to-one correspondence with the enterprises, and the edge between the two first-level points represents the flow relation of the two first-level points in the industrial chains; wherein the edge between the two second-level points represents the business relationship of the enterprises corresponding to the two first-level points, the attribute of each second-level point is the attribute of the corresponding enterprise, and the weight of the edge between the second-level points is determined according to the attribute of the corresponding enterprise of the second-level points.
