Research on the internalization and governance mechanism of ecological value in marine ranching:analysis framework based on dynamic optimal control
摘要
Abstract
To address the increasing pressure on marine fishery resources,this paper develops a dynamic optimal control model for marine ranching that internalizes its ecological value.The model transforms the value of ecosystem services into the resource's"shadow price"to quantify the difference between the social optimum and the open-access equilibrium.The study finds that,compared to the open-access equilibrium which leads to resource overexploitation,the socially optimal path exhibits a"high stock,low effort"characteristic.The steady-state equilibrium analysis further indicates that the optimal resource stock is positively related to ecological preferences and negatively related to the social discount rate.Furthermore,this paper demonstrates that Pigouvian taxes and Individual Transferable Quotas(ITQs)can effectively correct market failures.The core mechanism requires that the optimal tax rate or the equilibrium quota price must be equal to the resource's shadow price,thereby fully internalizing the externality.This research not only provides a theoretical framework for the governance of public resources in marine ranching that integrates economic efficiency and ecological value,but also reveals the central role of the shadow price in dynamic policy design,offering an operational scientific basis for achieving sustainable management.关键词
