摘　　要：讨论了生产和政府开支信息的随机波动对经济的影响.通过建立随机经济增长模型,得出在不同效用函数下资本和消费的最优增长轨道,以及随机增长率的表达式.并且分析了随机波动,政府开支资本比与随机增长率的相关性.Influence on economy from stochastic fluctuation of production and government expenditure is discussed. Optimization growth orbit of capital and consumption and the expression of stochastic growth rate are abtained under different utility functions by establishing stochastic economic growth model. The relativity of stochastic growth rate and stochastic fluctuation, as well as ratio of government expenditure to capital, is also analysed.
