摘要：

《民法典》完善了动产抵押的变动规则，扩张了动产担保的类型。在多种制度供给下，为了协调动产担保不同制度的法律适用，减少冲突，需要区分交易类型和动产类型进行分析。正常经营活动中的买受人无需关注动产上的权利负担，无论该负担是否登记，无论买受人善意与否，其物权取得均不受影响；正常经营活动以外的买受人则负有谨慎的注意义务，明知特定动产可能担保或者未查询登记，将会承受不利的后果。不同的动产类型可以适用的担保方式不同，法律效果也有差异，相对于经营主体较为固定的设备或者消费者的消费品，可以设立所有权保留、融资租赁或动产价款担保；针对经营主体以流通为目的的存货，更适宜设立“浮动”式担保。

Abstract:

The Civil Code of China perfected the rules of change for chattel mortgage and expanded the types of secured transactions.Under the supply of multiple systems，in order to coordinate the legal application of different systems of secured transactions and reduce conflicts，it is necessary to distinguish between transaction types and movable property types for analysis.Buyers in normal business activities do not need to pay attention to the burden of rights on movable properties，regardless of whether the burden is registered or not，regardless of whether the buyer is in good faith or not，the acquisition of property rights will not be affected；buyers outside of normal business activities otherwise have a duty of care，knowing that certain movable properties may be guaranteed or not inquired about registration，will suffer adverse consequences.Different types of movable property can be applied to different transactions methods，and their legal effects are also different.Compared with the relatively fixed equipment or consumer goods of the operating entity，ownership retention，financial leasing or purchase money security interests can be established；for the operating entity for the purpose of circulation inventory，it is more appropriate to establish a“floating”charge.
