摘要

纳米比亚住房普及率低,部分原因是建筑材料昂贵。作为一个开放的小型经济体,其建筑材料需求的很大一部分是进口的,汇率仍然是最终用户价格趋势的关键因素。本文分析了汇率与建材价格之间的二元关系,并将其分类为六类建材:砖瓦材料;屋面、门窗材料;管道材料;电子材料;耕绘材料;和总物料。相关系数结果从0.4751到0.8990不等,其中耕种和油漆和砌砖材料的相关系数最低,尽管总体上仍然很高,为0.5,而电气和管道材料的相关系数最高,分别为0.8990和0.7819。本文根据这些类别的进口构成来解释这些结果。与耕作和油漆材料相关系数最低的砌砖材料主要在当地生产,而相关系数最高的电气和管道材料主要是进口的

The Correlation between Exchange Rates and Selected Types of Building Materials Prices in Namibia, 2016-2021
Namibia is faced with low access levels to housing, a situation partly ascribed to costly building materials. As an open small economy which imports a significant share of its building materials requirements, the exchange rate remains key factor on the trend of end user prices. This paper analyzed bivariate relationships between the exchange rate and building material prices disaggregated in six categories of building materials namely: Brickwork materials; Roofing, doors & window materials; Plumbing materials; Electrical materials; Tilling & painting materials; and Total materials. The correlation coefficient results ranged from 0.4751 to 0.8990 with Tilling & Painting and brickwork materials having the lowest of all albeit generally still high correlation coefficient of 0.5 while Electrical and Plumbing materials have the highest correlation coefficients of 0.8990 and 0.7819 respectively. This paper interprets these results in line with composition of imports among these categories. Brickwork materials that have the lowest correlation coefficient alongside tilling and painting materials are predominantly produced locally while Electrical and plumbing materials with the highest correlation coefficients are predominantly imported
