边际产值 meaning in Chinese

value of marginal product
vmp

The changes of output elasticity of agricultural investment and marginal output indicate that institutional changes affect the agricultural investment effect
农业投资产出弹性和边际产值变化表明：制度变迁影响了农业投资绩效。
Recall from that lecture that the optimal allocation of fertilizer involves balancing the different fertilizers so the price of each fertilizer equals the marginal value product of that fertilizer
肥料的最佳分配应考虑不同肥料之间的平衡，使每一种肥料的价格都等于该肥料的边际产值。
Thus , for instance , in the example above , it may be the case that increased use of potash will increase the marginal value products of nitrogen and phosphate , thereby requiring an increase in their use as well
比如，在上述例子中，增施钾肥可能会增加氮肥和磷肥的边际产值，因而氮肥和磷肥的用量也需要提高。
Since the quantity of any one fertilizer influences the marginal value product of the other fertilizers , the optimal quantity of a particular fertilizer connot be chosen independently of the other fertilizers
由于任何一种肥料的用量均会影响其他肥料的边际产值，因此，一种肥料的最佳用量不能在不考虑其他肥料的情况下单独选定。
