Mixed-use development in Christchurch, New Zealand: Do you want to live there?

Christchurch, one of New Zealand’s major cities, has been dealing with a housing shortage after a series of major earthquakes struck in 2010 and 2011, causing extensive damage to the city. Consequently, two distinct types of housing development appeared in the suburban areas of Christchurch: low-density single-use neighbourhoods and higher-density mixed-use neighbourhoods. The latter type is relatively new for Christchurch suburban areas where low population densities dominated prior to 2011. Thus, this study aimed to investigate the preferences of the residents of Christchurch and its surrounding districts for living in mixed-use neighbourhoods. Specifically, it sought to identify the weights that those residents place on the costs of house purchase and transport, versus neighbourhood costs associated with mixed-use development, when purchasing a residential property in the suburban areas of Christchurch. For this, a stated preference survey was developed, using the efficient design method, and mixed-logit models were estimated using the data. The results show that most of those residents prefer to live in low-density single-use neighbourhoods rather than in higher-density mixed-use neighbourhoods, and are sensitive to increases in the land price, density of development and diversity of land use in the areas. 新西兰主要城市之一克赖斯特彻奇 （基督堂市） 2010 和 2011 年经历了一系列地震灾害， 对城市造成广泛损坏，此后一直面临住房紧缺。随之而来的，克赖斯特彻奇郊区出现了两 种截然不同的住房开发类型：低密度单一用途街区和高密度混合利用街区。在 2011 年之 前，克赖斯特彻奇郊区以低人口密度为主导，后一种类型相对而言是新来的事物。本研宄 旨在考察克赖斯特彻奇及周边地区居民对于在混合利用街区居住的偏好。具体而言，本文 希望厘清这些居民在克赖斯特彻奇郊区购买住宅物业时，对购房和交通成本相比与混合利 用相关的街区成本所做的权衡。为此，我们运用有效设计的方法制定了一项自述偏好调查, 并运用所得数据估测了混合评定模型。结果显示，大多数居民偏好于在低密度单一用途的 街区居住，而非在高密度混合利用街区居住，并且对该地区地价的攀升以及开发密度和土 地利用多样性的增强颇为敏感。
