Coastal management involves multiple possible actions at various spatial scales. Yet, what determines in practice the scale and scope of coastal management? To address this question we investigate two possible explanations for the scale and scope of coastal management regimes: an economic explanation, focusing on the costs and benefits of widening the scale and scope of such management regimes, and an environmental explanation, focusing on the environmental issues and threats. To test these explanations, we analyze the relations between the economic and environmental dimensions and the scale and scope of coastal management in 17 Mediterranean countries using the co-plot method based on The Mediterranean Action Plan data.

While we do find wider scale and scope of coastal management in countries with higher disposable income, these do not seem to be clearly and directly related to the intensity of specific economic activities that are more sensitive to environmental degradation or to level of pollution in coastal zone.

沿海管理涉及在各种空间尺度上的多种可能的行动。但是，在实践中，什么决定了沿海管理的规模和范围？为了解决这个问题，我们研究了两种有关沿海管理制度规模和范围的可能解释：一种经济解释，侧重于扩大此类管理制度的规模和范围的成本和收益；以及一种环境解释，侧重于环境问题。和威胁。为了检验这些解释，我们使用基于地中海行动计划数据的协同绘图方法，分析了17个地中海国家的经济和环境维度与沿海管理规模和范围之间的关系。

虽然我们确实发现，在可支配收入较高的国家中，海岸带管理的规模和范围更广，但这些似乎与特定的经济活动的强度并没有直接的关系，而这些活动对环境退化或沿海地区的污染水平更为敏感。
