国际侦查合作的执行主体是一个相对独立的理论范畴,与其上位理论范畴──国际侦查合作主体既有联系又有区别。形成这一理论范畴的现实原因是,国际侦查合作的微观运行层面表现为得到授权的国家机关就具体的国际犯罪或跨国犯罪案件进行侦查、开展合作的过程。根据性质不同,将国际侦查合作执行主体分为警察机关、检察机关、行使侦查权的其他机关及非侦查机关,并对其逐一进行理论探讨。 The executive subject of international investigation and cooperation is a relatively independent theoretical category, which has both the connection and the distinction with the subject theory of its own - the subject of international investigation cooperation. The realistic reason for forming this theoretical category is that the microscopic operational level of international investigation and cooperation is manifested in the process of cooperation and investigation conducted by authorized state organs in cases of specific international crimes or transnational crimes. According to their different nature, the executive bodies of international investigation cooperation are divided into police organs, procuratorial organs, other organs that exercise investigative powers and non-investigation organs, and conduct theoretical discussions one by one.
