Stainless steel square tube is currently in the process of industrial structure adjustment. If it encounters a sharp fall in steel market prices due to overcapacity, it might be difficult to sufficiently emphasize and call for a unified production cut or output restriction across the entire industry. Recent policy awareness or policy indications show that advanced productivity projects and their products possessed by some state-owned large and super-large national key backbone steel enterprises may not easily reduce production during future industrial structure adjustments. This could mean that companies or capacities will achieve "survival of the fittest" based on their ability to withstand market pressure, gradually creating an effective competitive environment where market truly optimizes resource allocation. Relevant industry organizations may not "require" the entire industry to implement a unified "production cut" as they did in the past, but instead may take this opportunity to work towards creating a true market "survival of the fittest" environment to balance supply and demand as well as capacity.
