With the development of large-scale national construction to a certain historical stage, the reduction of cement demand is inevitable, and the scale of production capacity and supply capacity can not be synchronized with the decline of demand in the short term. In particular, the cement industry has suffered from serious overcapacity for more than a decade. Although the state has made great efforts to resolve the contradiction of excess capacity and achieved certain stage results, due to the continuous shrinkage of market demand in recent years, the "involution" dilemma faced by the industry has become increasingly prominent, and overcapacity is still a "roadblock" restricting the high-quality development of the whole cement industry.
