Migrant workers’ wage deposit system has been actively explored and innovated in terms of diversifying payment methods，dispersing payment subjects，optimizing payment mechanism and standards and implementing differentiated management models in different regions by focusing on key industries. These reforms have achieved remarkable results，which are conducive to building a unified market，promoting fair competition，and further reducing the burden on enterprises. Meanwhile，imbalances of the reform still exist. The reform progress varies in different places；the corporate burden is relatively heavy in some regions；bank letter of guarantee and other non-cash payment methods have not been fully launched which resulted in inequality；the refund system of wage deposit needs to be optimized. It is suggested that regions with slow reform progress should consider the advanced areas as a benchmark，to speed up the reform progress，and further reduce the payment burden for enterprises；the eligible localities are allowed to phase out the wage deposit paid by enterprises by categories；further improve non-cash payment mechanisms such as bank letter of guarantee to improve coverage and fairness；continue to optimize the refund mechanism of wage deposit and further relieve cash flow pressure for enterprises.
