From the perspective of commodity classification, the import of resource commodities in August continued the month-on-month improvement trend since June, but there was also a corresponding differentiation, in which the recovery of industrial raw materials was strong and crude oil and natural gas were relatively weak. Specifically, the import of iron ore and concentrate has increased for three consecutive months, and the year-on-year growth rate has turned from negative to positive; Imports of copper ore, aluminum ore and concentrate increased significantly year-on-year and quarter-on-quarter; The year-on-year growth rate of coal and lignite imports turned from negative to positive, and the cumulative year-on-year decline narrowed; Imports of crude oil and natural gas increased for two consecutive months, but the year-on-year decline was still above 10%. ? Wei Gang, chief economist of Hengtai Futures, said in an interview with the reporter of Futures Daily that overall, the demand for bulk resource products continued to improve in August, and the industrial production boom continued to pick up.
