摘要
本文研究投资的综合经济效益。由于一项投资不仅带来直接效益,而且往往也促进了其他领域的发展,带来间接效益。我们把直接效益与间接效益之和称为综合效益,讨论它的一些重要性质。我们的主要结论是:综合剩余模式的形状比较复杂,这种复杂性可能是人们难以认识和评估综合效益的部分原因。
We study the comprehensive benefit of investment. Some investment not only bring direct benefit for itself, but also create oppotunity for the development of other fields, obtsining indirect benefit,We call the sum of direct benefit and indirect benefit as comprehensive benefit, and analyze some of its crucial properties. The main results are: 1) the form of the comprehensive pattern of surplus(CPS) is complicated, which can partly explain the difficulty to evaluate the comprehensive benefit. 2) the average profit of CPS is equal to weighted average of direct pattern of surplus and indirect pattern of surplus.
