一、问题的提出在市场经济中,若单从经济效益而言,资金投资的目的是为了货币的不断增值,也就是说资金是具有时间价值的,其具体表现形式为利息和利润。而在实际评价计算时,为了简便起见,一般是采用间断复利公式计算。但是,从理论上说,资金的时间价值应该是指资金连续性地增值,而非间断性的,即计息时间应是连续的,而不是区间性的。虽然二者的差距不会很大,然而,我们在建立一个较为复杂的技术经济数学模型时, First, the issue raised In a market economy, if from the economic benefits alone, the purpose of capital investment is to continuously add value to the currency, which means that the capital is a time value, and its specific form of performance for the interest and profits. In the actual evaluation calculation, for the sake of simplicity, is usually calculated using the intermittent compound formula. However, in theory, the time value of funds should refer to the continual appreciation of capital, rather than the continuity, that interest-bearing time should be continuous rather than intervalal. Although the gap between the two will not be great, however, when we establish a more complex technical and economic mathematical model,
