作为共同侵权行为的类型之一,共同危险行为不同于共同加害行为、无意思联络的数人侵权行为。对于数人侵权但又无法查明具体侵权人这类案件的处理,我国还未以制订法的形式予以确认,又受到很多因素的限制,许多案件不能得到合理的解决。因此,研究共同危险行为的相关问题至关重要。 As one of the types of joint infringement, the common dangerous behavior is different from the joint infringement and the unintentional connection of several human rights violations. For the cases of several cases of infringement, but unable to identify specific infringers, our country has not yet confirmed it in the form of formulation of laws and is subject to many factors. Many cases can not be solved reasonably. Therefore, it is of crucial importance to study the relevant issues of common dangerous behaviors.
