In order to predict the demand for important mineral resources in Liaoning Province during the 14th Five Year Plan period，based on the development and utilization of mineral resources during the 13th Five Year Plan period, the method of demand trend analysis is adopted to track the industrial chain, collect development and utilization data of upstream and downstream production links or consumption data of downstream product end markets, and predict the actual demand and guarantee capacity of iron ore, coal, gold mine, magnesite, flux limestone, and boron ore during the 14th Five Year Plan period. The results show that the demand for iron ore ranges from 183.75 million to 191.1 million tons/a, coal from 179.92 million to 191.35 million tons/a, gold from 8.11 million to 8.92 million tons/a, magnesite from 30.48 million to 33.81 million tons/a, limestone for flux from 14.96 million to 15.4 million tons/a, and boron from 4.16 million to 5.39 million tons/a in the next 5 years. The guarantee degree of magnesite and flux limestone is relatively high, which can achieve supply-demand balance. Gold ore requires a large amount of imports, and the guarantee degree of iron ore, coal, and boron ore is insufficient. It is necessary to further strengthen the exploration of deep and peripheral mineral resources, strengthen mining capacity construction.
