摘要
分析了一类经济投资方程的定态解特性，并计算了此类投资方程的定态解稳定性性质．通过计算发现，投资构形的稳定性与人们的投资心理和战略决策幅度有很大的关系．随着参数的变化，投资方程的定态解可能出现稳定焦点、稳定节点、不稳定焦点、不稳定结点以及鞍点等几种情况．
The characteristic of the state solution of economical investment equation is analyzed and its state solution is calculated. The stability of investment structure has a close relation to people's investment choice and strategic choice amplitude through calculation. The state solution of investment equation may be stable focus, stable node, unstable focus, unstable node or saddle point according to the parameters.
