本文研究了在古诺博弈中建立具有内生最低参与水平的区域渔业管理组织（RFMO）对跨界渔业合作可能性的影响——在两种情况下，RFMO 成员的合规执行无成本和成本高昂。 RFMO存在的最低参与水平是渔业国在谈判建立RFMO时一致选择的。结果表明，合作程度的提高导致稳态鱼类资源量和渔业总租金均呈递增趋势。最小参与水平的均衡是盈利联盟的最小合作水平。如果建立了具有内生最低参与水平的 RFMO，则 RFMO 稳定在最低参与水平的均衡状态。此外，与无需成本即可执行的 RFMO 相比，需要昂贵执行成本的 RFMO 通常在最低参与水平的平衡下涉及更高的合作水平。因此，如果区域渔业管理组织在执行成本高昂的情况下形成内生的最低参与水平，则不仅会导致稳态鱼类资源水平更高，而且还可能提高参与者的租金。最后，生物经济参数和参与跨界渔业的国家数量对区域渔业管理组织在何种情况下进行成本高昂的执法是否值得产生重大影响。
This paper examines the effect of establishing a regional fishery management organisation (RFMO) with an endogenous minimum participation level on cooperative possibilities in straddling stock fisheries within the Cournot game in both cases – costless and costly enforcement for compliance of RFMO's members. The minimum participation level for the existence of an RFMO is unanimously chosen by fishing countries when negotiating the establishment of the RFMO. The result shows that an increase in cooperation level leads to an increase with an increasing rate in both steady-state fish stock and total rent of the fishery. The equilibrium of the minimum participation level is at the smallest cooperative level for a profitable coalition. If an RFMO with an endogenous minimum participation level is established, the RFMO is stable at the equilibrium of the minimum participation level. Furthermore, an RFMO that requires costly enforcement typically involves a greater cooperative level at the equilibrium of the minimum participation level than an RFMO that could be enforced without cost. Consequently, if an RFMO forms with an endogenous minimum participation level in the case of costly enforcement, it not only results in a higher level of steady-state fish stock, but it also may improve the rent of a participant. Finally, the bio-economic parameters and the number of countries involved in straddling stock fisheries have a significant effect on circumstances under which an RFMO with costly enforcement becomes worthwhile.
