参考:
the production process for a specific good or service exhibits economies of scaleover a range of output when average cost (i.e., cost per unit of output) declines over that range. if average cost (ac) declines as output increases, then the marginal cost of the last unit produced (mc) must be less than the average cost. 1 if average cost is increasing, then marginal cost must exceed average cost, and we say that production exhibits diseconomies of scale.
