边际收入等于边际成本 marginal revenue equals marginal cost
当收入函数、成本函数为连续可微函数,边际收入等于边际成本,即边际利润等于零时,利润最大;但在离散情况下,上述结论不一定成立,并给出反例。
In this paper I get the profit be maximum, as the revenue function, cost function are continuous differential and the margin revenue equals margin cost, that marginal profit equals zero.
It's where the marginal revenue is equal to the marginal costs.
