The recognition of common benefits debt is related to the realization of the concept of fair distribution in the bankruptcy law, and the determination of the total benefits of debt depends on the “common benefits standard”. Scholars essentially adopted the “absolute procedure standard” to identify common benefits debt; the debt must be of common benefits as long as it happens after the application for bankruptcy is accepted. However, the “absolute procedure standard” ignored the complexity of reality so that the setting purpose of the common benefits system has a risk of being unattained. And the use of “double standard” not only can make up for the defects of the “absolute procedure standard”, but also is in line with the concept of strict control of the priority of discharge. The wrong academic choice of “absolute procedure standard” results in the unscientific provisions of China's empirical law. “Double standards” are needed to eliminate the false elements of the common benefits so that the common benefits debt can truly be of the essence of common benefits.
