The features of some cultural goods allow them to be exhibited in a unified form in one location or separated for display in two or more locations. The aim of the present article is to understand whether the decision to expose a cultural good in two different cities instead of the same location could generate benefits for both. To do so, the case of the Giants of Mont’e Prama is analysed. This recognised heritage complex of archaeological stone statues was found in Sardinia (Italy) in 1974 and first displayed in 2014. Since 2014, interest in these statues has increased among both residents and tourists. Moreover, the location of the exhibition was the subject of a strong discussion among historians and politicians. Historians preferred to display all the statues together in Cabras, where they were found. However, politicians and other authorities decided to divide the statues between Cabras and Cagliari, the regional capital, thus separating the collection into two exhibitions. This analysis is carried out to capture potential spill-over effects in visitors’ behaviour and identify which exposition causes visits to the other. The results indicated that the exposition system is a win–win solution, and the negative effect of overtourism is not observed.

一些文化产品的特征使它们可以在一个位置以统一的形式展示或在两个或多个位置分开展示。本文的目的是了解决定在两个不同的城市而不是在同一地点展示一种文化产品是否可以为两者带来好处。为此，分析了“蒙特普拉玛巨人”案。1974年在撒丁岛（意大利）发现了这种公认的考古石像文物，并于2014年首次展出。自2014年以来，居民和游客对这些石像的兴趣不断增加。此外，展览的地点是历史学家和政治家之间激烈讨论的主题。历史学家宁愿将所有雕像一起陈列在卡布拉斯，在那里被发现。然而，政治家和其他当局决定将雕像分为地区首都卡布拉斯和卡利亚里，从而将藏品分为两个展览。进行此分析是为了捕获访问者行为中的潜在溢出效应，并确定哪个博览会引起了另一个访问。结果表明，博览会系统是一个双赢的解决方案，并且没有观察到过度旅游的负面影响。
