The design and the evaluation of sustainable tourism policies require involving all the actors in the decision-making process. One of the critical aspects at the regional level is the absence of a clear definition of instruments and methodologies able to involve all the actors and to meet different policy targets. The aim of this study is to assess the economic and environmental impact of the tourism carrying capacity by proposing a framework able to deal with multiple variables. To this end, a social accounting matrix is built for a local area composed by four municipalities within the Sardinia region (Italy), and then it is used as a reference frame to implement the extended multisectoral model. Such an approach will provide results, on visitors flow recorded in the Asinara National Park, in terms of value added and CO2 emissions changes.

可持续旅游政策的设计和评估需要所有参与者参与决策过程。区域层面的一个关键方面是缺乏能够让所有参与者参与并满足不同政策目标的工具和方法的明确定义。本研究的目的是通过提出一个能够处理多个变量的框架来评估旅游承载能力的经济和环境影响。为此，针对撒丁岛地区（意大利）内的四个自治市组成的当地区域构建了一个社会核算矩阵，然后将其作为参考框架来实施扩展的多部门模型。这种方法将提供有关在阿西纳拉国家公园记录的游客流量的附加值和二氧化碳排放变化方面的结果。
