| 摘 要： | 运用随机微分方程的理论和知识,对随机R＆D模型中人口不确定性进行相关的研究.研究发现：模型能够得到随机状态下全局稳态均衡存在的条件,也能保证该均衡点的唯一性;同时如果期望的人口增长率满足一定的条件,其改变不会影响经济增长的长期趋势.

| Abstract: | This paper analyzes population growth uncertainty in stochastic R＆D model by using stochastic differential equations. Based on this research, the condition of global equilibrium existence can be found, and solution uniqueness can be guaranteed. Meanwhile, if the expected population growth rate satisfies some demands, its change will not affect the long-term trend of economic growth. |
