摘要： 当多个动产抵押权竞存、一般动产抵押权与浮动抵押权竞存、动产抵押权与质权竞存时，不区分“善意恶意”，统一按照公示的先后顺序决定优先顺位。动产抵押权人与担保物买受人竞存时，若买受人属于“正常交易中的买受人”，无论抵押权是否登记，也无论买受人是否知道抵押权，买受人都无负担地取得标的物所有权；若买受人并非“正常交易中的买受人”，则仅在抵押权未登记，且买受人善意时，买受人无负担地取得标的物所有权；若抵押权已经登记，无论买受人是否为善意，抵押权都优先。现行的所有权保留制度与动产抵押制度存在冲突，未来有必要建立所有权保留的公示制度。

Abstract: When the coexistence of several chattel mortgages occurs, or the coexistence of chattel mortgage and floating charge occurs, or the coexistence of chattel mortgage and pledge occurs, priority should be made without considerations of publicity sequences, without distinction of bona fide and mala fide.When the coexistence of chattel mortgagee and the buyer of guaranty occurs, (1)if the buyer is in ordinary course of business, the buyer could obtain the ownership of the object without any burdens, no matter whether mortgage has been registered and whether the buyer knows the existence of the mortgage；(2)if the buyer is not in ordinary course of business, only when the mortgagee made no registration and in bona fide, the buyer could obtain the object without any burdens；if the mortgagee made registration before the possession of the object by the buyer, no matter whether the buyer is in bona fide, mortgagee enjoys the priority.Due to the conflict of the ownership reservation and chattel mortgage, therefore it is necessary to establish a complete registration system.
