Abstract: Based on the evolutionary game theory,the paper revealed two main challenges in the process of substitution from self-sufficiency to labor division.One is the co-ordination problem for labor division.The other one is that the strategy of self-sufficiency risk dominates the strategy of labor division.After that,the paper explored how the people in the reality solved those problems.And at last drew the conclusions that the co-ordination problem can be automatically resolved by the natural selection for the survival of the fittest,and depending on the establishment of some institutions such as urban and fair,the problem of risk domination could be resolved.
