Abstract: The system of non-prosecution for enterprise compliance has come into being in an era of optimizing the business environment, moreover, the micro-transformation of the concept of legal protection, the new development of the policy of temper justice with mercy, and the re-understanding of the nature of unit crime also provide legitimate support for the non-prosecution system of enterprise compliance. However, the smooth operation of the non-prosecution system of enterprise compliance is still restricted by the connecting problem of Investigation and prosecution, which cannot be ignored. The poor connection between investigation and prosecution will seriously weaken the role of the non-prosecution system in optimizing the business environment. The main reason for the poor connection between investigation and prosecution lies in the inherent drawbacks of the current "pipelined justice" system. In order to solve this problem, we should try to turn to the mode of "problem-solving justice", construct the cooperative relationship of investigation and prosecution with the support supervision as the core element, and properly handle the task of removing reasonable suspicion.
