According to recent recession of Macau's economy，some residents would doubt the sustainability of Macau public pension system，even though Macau SAR Government has already introduced various measures，including voluntary central provident fund，diversifying the financing mechanism and increasing the“symbolic”contribution amount of public pension system，to convert Macau's public pension into a long-term sustainable system.The public's doubt also triggers the argument over contribution ratio between employer and employee.For the sake of exploring the issue of building sustainable public pension system and the contribution arrangement，the paper is to analyse the contribution arrangement of OCED countries and to use the results of 2015 telephone survey of Macau residents' opinion on Macau's public pension system.According to patterns of the contribution arrangement of OCED countries，there is no unified contribution arrangement，but the higher total contribution would lead to higher employers' contribution rates over employees'.The finding could echo Macau's employers' concern about the trend. Macau Government can reference to Mainland China's public pension system for integration between Macau and Mainland China，as well as，she can develop retirement finance market for industrial diversification and ease the issue of“Asset Rich，Cash Poor”.
