ABSTRACT This paper presents a social network analysis of twenty-five municipalities within Greater Melbourne to determine which organizations are most central in urban sustainability work. By analysing how cities' urban sustainability documents cross-reference each other, I find a geographic pattern of collaboration from the city centre northwards to the urban fringe. State government agencies and regional utilities are the most important external organizations. The results confirm a multi-scalar approach to understanding local governments and urban sustainability, while emphasizing multiple approaches of local governments within a metropolitan region. Furthermore, water was the key to defining sustainability in Greater Melbourne in the mid-2010s.

在城市可持续发展方面进行合作：大墨尔本地区市政的社会网络分析

摘要本文介绍了对大墨尔本地区25个城市的社会网络分析，以确定哪些组织在城市可持续发展工作中最重要。通过分析城市的城市可持续性文档之间如何相互参照，我发现了从市中心向北到城市边缘的协作地理模式。州政府机构和区域公用事业是最重要的外部组织。结果证实了采用多尺度方法来理解地方政府和城市可持续性，同时强调了大城市区域内地方政府的多种方法。此外，水是2010年代中期定义大墨尔本地区可持续发展的关键。
