摘要：伴随着 “一带一路” 倡议的推进，装配式钢结构建筑因其在绿色、高效、可持续方面的独特优势在沿线国家应用日益广泛。本文从设计、生产、运输、安装四个方面，对比构建了国产装配式钢结构建筑出口新西兰、新西兰当地采购生产以及当地混凝土现浇三种方案的成本计算模型，并结合案例对比计算了三种方案的成本，最后基于灰色关联度分析进行了复核计算，以期为我国装配式钢结构建筑拓展 “一带一路” 市场提供依据与实践参考。

Abstract：With the advancement of the "Belt and Road" initiative，prefabricated steel structure buildings have seen increasingly widespread application in the countries along the route，owing to their unique advantages in terms of greenness，efficiency，and sustainability. This paper constructs a cost calculation model for three scenarios：exporting Chinese-made prefabricated steel structure buildings to New Zealand，local procurement and production in New Zealand，and local cast-in-place concrete construction. The comparison is conducted from four aspects：design，production，transportation，and installation. Furthermore，the costs of the three scenarios are calculated and compared based on a case study. Finally，a review calculation is performed using grey relational analysis，aiming to provide a basis and practical reference for the expansion of China's prefabricated steel structure buildings in the "Belt and Road" market.
