摘要
在文献[1]的基础上,给出了企业预期寿命的形式定义,建立了预期寿命的数学模型,并导出了预期寿命的一般数学表达式。同时通过实例计算对模型的具体求解进行了分析。
On the basis of Reference[1], this paper presents the mathematical definitionand the mathematical model of the firm's expected life. This model is a randomwalk with an absorbing barrier and a reflecting barrier. For discrete profit distri-butions the model can be analyzed by the difference equations. For continuousprofit distributions the model usually leads to fairly complicated mathematicalproblems. To illustrate this, the paper gives realistic examples.
