The basis of industry is raw materials. The price increase of raw materials directly affects the subsequent industrial development, so product prices will also rise. In the last period of time, some raw materials have risen, especially some metal materials, such as copper, aluminum and iron, which have risen by 38%, 37% and 30% respectively. This kind of increase is still very obvious. Affected by the increase in raw material prices, some industrial products have also begun to experience price increases. In addition, not only the price of metal materials has risen, but the prices of some non-metallic materials have also begun to rise. The more obvious ones are glass and plastics, which have risen by 35% and 30% respectively. This kind of increase is also very large in the past. , So the price of various raw materials has risen by more than 30%. Who is behind it and what is the impact?
