（一）客体要件

本罪侵犯的客体是国家重点保护的珍贵、濒危野生动物的管理制度。本罪的对象只能是国家重点保护的珍贵、濒危野生动物及其制品。

（二）客观要件

本罪在客观方面表现为违反野生动物保**规，收购、运输、出售珍贵、濒危野生动物及其制品的行为。

所谓收购，是指未经有关部门批准以金钱作价，购买珍贵、濒危野生动物及其制品的行为；所谓运输，是指未经批准，私自运输珍贵、濒危野生动物及其制品的行为；所谓出售，是指未经批准，以牟利为目的出价售卖珍贵、濒危野生动物及其制品的行为，至于是否已实际获得利益，并不影响犯罪的成立。

无论行为人实施的是其中一种行为，还是同时实施数种行为，均可构成本罪。

定罪标准目前尚无明确的规定，在新的司法解释出台之前，可以参照林业部、公安部《关于陆生野生动物刑事案件的管辖及其立案标准的规定》。

（三）主体要件

本罪的主体为一般主体，即凡是达到刑事责任年龄具有刑事责任能力的人，均可构成本罪。前段时间也可成为本罪主体。

（四）主观要件

本罪在主观方面表现为故意，过失不构成本罪。实践中，由于一些非专业人员对野生动物领域了解不多，因而通常对何种动物为野生动物的认识不够，也因此对该种动物制品缺乏认识，在这种情况下实施了非法收购、运输、出售自己认为是珍贵、濒危野生动物及其制品的，一般不以本罪论处；如果行为人实施了非法收购、运输、出售自己认为不是珍贵、濒危野生动物及其制品的，而事实上确实是珍贵、濒危野生动物及其制品，亦不宜以本罪论处。

The so-called acquisition refers to the purchase of precious and endangered wild animals and their products at the price of money without the approval of the relevant departments; The so-called transportation refers to the unauthorized transportation of precious and endangered wild animals and their products; The so-called sale refers to the act of selling precious and endangered wild animals and their products without approval for the purpose of making profits.

Whether the actor performs one of the acts or several acts at the same time, it can constitute this crime.

（3） Main elements

The subject of this crime is the general subject, that is, anyone who reaches the age of criminal responsibility and has the ability of criminal responsibility can constitute this crime. It can also be the subject of this crime in the previous period.

（4） Subjective element

The subjective aspect of this crime is intentional, and negligence does not constitute this crime. In practice, because some non-professional personnel do not know much about the field of wild animals, they usually do not know enough about what kind of animals are wild animals, and therefore do not know enough about this kind of animal products. In this case, those who illegally purchase, transport and sell what they think are precious and endangered wild animals and their products are generally not punished for this crime; If the perpetrator illegally purchases, transports and sells wild animals and their products that he considers not to be precious or endangered, but in fact are precious or endangered wild animals and their products, it should not be punished for this crime.
