In the investigation practice, the investigation mode is always an important research object that runs through
the investigation process and decides whether the investigation can realize its value. It can not be denied that the
investigation mode with investigation as the center has played an important role in the specific historical period, but
with the criminal situation becoming more and more complex, the investigation mode with investigation as the center
of the investigation is the arrest of the confession file, the trial is empty, the investigation power is short of restriction,
and the criminal suspect has not been given the necessary and effective means of relief. The reform of the investigation
mode centered on trial came into being. Under the doctrine of trial centralization, the transformation of investigation
mode from “offering to evidence” to “offering to evidence ”,“ pursuing the quantity of solving cases” to “pursuing the
quality of solving cases ”,“ attaching importance to the combination of restriction” and “attaching importance to the
contract and light cooperation” has provided a good direction for the benign development of the investigation mode in
our country under the new changes in the new period.
