At present, with the adjustment of the structure of the steel industry, the steel logistics industry is also engaged in integrating. Steel logistics resource integration is an important problem to be solved. Based on previous research on steel logistics resource integration, this paper proposes a new research perspective on steel logistics resources integration: supply-demand network of steel logistics. This paper analyzes characteristic of supply-demand network of steel logistics, proposes connotation of steel logistics resources integration based on supply-demand network of steel logistics, which is integrating supply organization and demand organization of steel logistics service as a whole network, restructuring and optimizing allocation of steel logistics resources by the means of constructing steel logistics service supply chain, and integrating steel logistics service supply chain and steel products supply chain into an integrated steel supply chain. This new research perspective has great significance to expand the range and boundary of steel logistics resources and realize the linkage and win-win of logistics industry and steel industry.
