资本配置效率的研究是一个非常有价值的课题,按照新古典经济学的观点,在完全竞争的市场条件下,资本配置的帕累托最优的充分必要条件是,各个项目之间的边际成本之比处处等于相应的价格之比,即各项目之间的边际收益率处处相等。如果项目A的边际收益率大于项目B,那么增加项目A的投资,同时减少项目B的投资,可以实现资本
The research on the efficiency of capital allocation is a very valuable subject. According to neoclassical economics, under the perfectly competitive market conditions, the Pareto optimality of capital allocation is the necessary and sufficient condition that the marginal cost between the various projects Ratio is equal to the ratio of the corresponding price, that is, the marginal rate of return among the projects are the same everywhere. If the marginal rate of return for project A is greater than for project B, capital is increased by increasing investment in project A while reducing investment in project B
