Critical productivity of enterprises

Critical productivity of an enterprise: marginal productivity is the first derivative of the production function, which refers to the output increased by each unit of production factors (such as labor and capital) in various industries.

When the marginal productivity is too low or close to zero, it means that the development scale of the industry is close to saturation, and human and material resources should be transferred to other industries. When only one factor of production is variable (such as capital), marginal productivity is marginal product.
