The results of t-test analysis show that the performance of stores with partnership system is significantly better than that of stores with non partnership system. In descriptive statistics and t-test statistical analysis, it is found that the impact of turnover rate on performance income is positively correlated between enterprises with partners and enterprises without partners. However, the comparative analysis of the two groups of data shows that in the enterprises that adopt the partnership system, the performance income decreases more with the increase of the turnover rate, but the decline is more gentle compared with the enterprises that do not adopt the partnership system.

Therefore, it can be deduced that the enterprises adopting the partner system are stronger than other enterprises in dealing with the adverse impact of employee turnover on the performance.It shows that the partnership system can enable enterprises to maintain stable performance income in the face of personnel change.
