Within the theoretical framework of construction grammar,the paper explores the principle by which causer argument is realized.Different from English resultatives which follows the semantic coherence principle strictly,causer argument in Chinese resultatives can fuse with verb’s agent,combine with verb’s theme,or be contributed by construction solely.As long as an entity has the ability to affect another entity and make it change state,no matter what semantic relation it has to the verb in V position,or whether they have semantic relation,it can be expressed as causer in Chinese causative resultatives.In order to emphasize the causer,it should be noun phrase with complex modifier or high degree of definiteness.
