Abstract
Illegal mining activities on offshore sands have recently increased
dramatically in China owing to the strong demand of the construction industry and restriction of river sand mining. By studying
the loss mechanism of marine sand resources, this study proposes
a simplified linear programming model to quantitatively analyse
the control effects related to resource loss and law enforcement
costs. To accurately simulate the effectiveness of law enforcement
activity, a set of variables is designed in the model to describe
the severity of illegal mining and enforcement skills of the officers. Subsequently, based on different settings of law enforcement capability, the model can not only make reasonable
projections for sand losses but also provide a minimum cost solution for marine sand control for government agencies. Finally,
various regulatory measurements and suggestions are discussed
to improve the effectiveness of the government’s regularisation
and cost optimisation for law enforcement.
