Abstract Home ownership is the usual form of tenancy in Spain and is particularly widespread across all social classes for different historical and cultural reasons. In this context, multiple property ownership (MPO) is not limited to the wealthy. It takes on different forms that have different explanations. Statistics reveal the existence of millions of second homes, private rented properties and a vast number of vacant houses, all of which are illustrative of a complex residential environment. This paper aims to quantify and analyse the types of multiple property in Spain from the demand side, focusing on individual and household owners, drawing on a variety of quantitative data sources. On the aggregate level, the number and type of multiple properties varies depending on geographical factors (coast versus inland; rural versus urban) and the characteristics of the buildings. On the micro level, we have used individual variables to model the demand-side determinants of single property and MPO. This reveals that the relevant variables are not the same for the two groups. MPO in Spain is not only linked to socioeconomic status and savings capacity, pointing to the need for more differentiated explanations.

西班牙多重财产所有权的需求侧决定因素

摘要 拥有房屋是西班牙常见的租赁形式，由于不同的历史和文化原因，它在所有社会阶层中尤为普遍。在这种情况下，多重财产所有权 (MPO) 不仅限于富人。它采取不同的形式，有不同的解释。统计数据显示，存在数以百万计的第二套住房、私人出租物业和大量空置房屋，所有这些都说明了复杂的居住环境。本文旨在从需求侧量化分析西班牙多重房产的类型，重点关注个人和家庭业主，借鉴多种量化数据来源。在总体层面上，多个物业的数量和类型取决于地理因素（沿海与内陆；农村与城市）和建筑物的特征。在微观层面，我们使用个别变量对单一财产和 MPO 的需求侧决定因素进行建模。这表明两组的相关变量并不相同。西班牙的 MPO 不仅与社会经济地位和储蓄能力有关，还表明需要更多差异化的解释。
