Abstract This paper investigates planning and development processes of networked infrastructure systems from an institutional perspective. It applies theories of ASID (agency, structure, institutions, and discourse) and discursive institutionalism to unveil simplistic structure-agency imaginaries of infrastructure planning. The concept of discursive institutionalism puts emphasis on ideas that are discursively constructed by agents, forming the basis for collective action. This allows understanding of (1) the idealised structure of society, (2) the envisioned future city, and (3) the disciplinary self-conception of “good planning” as key intermediary instances of development and change. Through the case study of the Aspern area in north-eastern Vienna, the paper explores the origins of material urban transformations from cropland to strategic development site by focusing on the discursive institutionalisations of infrastructure planning since 1954. It points to institutionally stable phases of infrastructure planning as well as critical transitions in the planning system – all shaping Aspern’s subsequent development. Retracing this process through content analysis, interviews and archival research serves as an explanation to the multi-layered interdependencies of the entailing realisation of a small-scale urban development project. Herewith, the research contributes to a better understanding of the impact of planning discourse on urban development and the discursive institutionalisation of infrastructure planning.

Aspern 解释：基础设施规划的话语制度化如何塑造维也纳东北部的城市转型

摘要 本文从制度的角度研究了网络化基础设施系统的规划和发展过程。它应用 ASID（代理、结构、制度和话语）和话语制度主义的理论来揭示基础设施规划的简单结构代理想象。话语制度主义的概念强调由代理人话语构建的思想，形成集体行动的基础。这允许理解 (1) 理想化的社会结构，(2) 设想的未来城市，以及 (3) 作为发展和变化的关键中介实例的“良好规划”的学科自我概念。通过对维也纳东北部 Aspern 地区的案例研究，该论文通过关注 1954 年以来基础设施规划的话语制度化，探讨了从农田到战略开发地点的物质城市转型的起源。它指出了基础设施规划的制度稳定阶段以及规划系统的关键转变——所有这些都塑造了 Aspern 随后的发展发展。通过内容分析、访谈和档案研究回顾这一过程，可以解释小规模城市发展项目的实现的多层次相互依存关系。因此，该研究有助于更好地理解规划话语对城市发展的影响以及基础设施规划的话语制度化。
