论文分析表明：在偏好、个人劳动能力和个人收入的随机冲击的影响下，如果市场是完善的，整个经济系统存在收入和财富分配的稳定不平等状态，而且，这种稳定的不平等状态与初始的财富分配的不平等和一次性的产权配置都是无关的。
The traditional methods of times series can not be used for the unit root process . but economic phenomenon has long term equilibria relationship between each other , so we can seek cointegration for the multi - unit root process . if they have cointegration relationship , there must be long term equilibrium among them while other factors act as short - term impact
对于具有单位根过程的经济指标数据，传统的时间序列方法不能使用，但是经济现象往往又表现出它们之间具有的长期均衡关系，因此，对于多个单位根过程，可以寻求它们之间的协整关系，如果经济指标之间具有协整关系，则它们之间就具有长期均衡关系，而其它因素的作用只是短期随机冲击而已。
