In the 2016 edition of Archives Law, the proportion of soft law clauses was 45.12%, while in the 2020 edition of Archives Law, the proportion of soft law clauses reached 79.33%, up 34.21%. In practice, although soft law clauses may lead to the weakening of the enforcement of Archives Law, they also have their "rationality" and "inevitability". This "rationality" and "inevitability" can be proved from the three dimensions of direct motivation, indirect motivation and substantive motivation. After reviewing the operation of the 2020 edition of Archives Law, it can be found that the soft law clauses do not have enforcement power, but there are unique endogenous enforcement mechanisms and exogenous enforcement mechanisms. Facing the future, in order to improve the "landing" effect of the 2020 Edition of Archives Law, we should focus on the soft law clauses and achieve the established legislative purpose by "improving" the soft law clauses. Specifically, we should optimize the external enforcement mechanism of "soft law clauses" by building a "joint enforcement mechanism"; Take "legislative participation and balance of legal interests" as the specific path to stimulate the self implementation potential of "soft law clauses".
