中文摘要：

个体企业要想生存与发展，必须跟随企业种群演化的步伐，这就需要企业适时对适当的要素进行变革。所以确定企业变革时点和要素非常关键。企业在长期的发展中，形成指导自身行为的“基因”，即惯例，随着外界环境的变化，企业需要改善自身惯例库，即发生变革。企业通过对自身适应能力的实时监控，确定变革时点；将自身惯例与种群中优秀的惯例对比，通过基于遗传算法的种群学习，确定变革的惯例要素，用种群中优秀的惯例替代不适惯例，为变革指明方向，从而不断适应外部环境的变化。

英文摘要：

In order to adapt to environmental changes, enterprise group learns continuously and achieves its own evolution. If individual enterprises want to survive and develop, they must follow the pace of the evolution of enterprise group, and make the simultaneous evolution, which requires enterprises a timely and appropriate change, so how to define the time point of change and the elements of change is crucial. Enterprise group learning provides us with inspiration and enlighten. development, enterprises ＂gene＂, which guides their acts, are formed, that of the external environment, enterprises need to improve their routines, In their long-term survival and is the routines. With the changes which need enterprise changes. Enterprises determine their time point of changes by detecting their own ability to external environment. Then, enterprises contrast their own routines with excellent routines in enterprise group, through the group learning based on genetic algorithm, identify the elements of change, and choose the excellent routines enterprise group taking the place of the poor ones. Then change direction is defined so as to continuously adapt to changes in the external environment.
