Global sustainability governance is marked by a highly fragmented system of distinct clusters of international organizations, along with states and other actors. Enhancing inter-organizational coordination and cooperation is thus often recognized as an important reform challenge in global sustainability governance. The 17 Sustainable Development Goals, agreed by the United Nations in 2015, thus explicitly aim at advancing policy coherence and institutional integration among the myriad international institutions. Yet, have these goals been effective in this regard? We assess here the impact of the Sustainable Development Goals on the network structure of 276 international organizations in the period 2012–2019, that is, four years before and four years after the launch of the Sustainable Development Goals. The network structure was approximated by analyzing data from the websites of these 276 international organizations that were joined by more than 1.5 million hyperlinks, which we collected using a custom-made web crawler. Our findings are contrary to what is widely expected from the Sustainable Development Goals: we find that fragmentation has in fact increased after the Sustainable Development Goals came into effect. In addition, silos are increasing around the 17 SDGs as well as around the social, economic, and environmental dimensions of sustainable development.

全球可持续性治理的特点是由不同的国际组织集群以及国家和其他行为者组成的高度分散的系统。因此，加强组织间协调与合作通常被认为是全球可持续性治理中的一项重要改革挑战。因此，联合国于 2015 年商定的 17 项可持续发展目标明确旨在促进无数国际机构之间的政策一致性和机构整合。然而，这些目标在这方面是否有效？我们在此评估了 2012-2019 年期间，即可持续发展目标启动前四年和启动后四年，可持续发展目标对 276 个国际组织网络结构的影响。通过分析来自这 276 个国际组织的网站的数据来近似网络结构，这些数据由超过 150 万个超链接加入，我们使用定制的网络爬虫收集这些数据。我们的发现与可持续发展目标的普遍预期相反：我们发现，在可持续发展目标生效后，碎片化实际上有所增加。此外，围绕 17 个可持续发展目标以及可持续发展的社会、经济和环境层面的孤岛正在增加。我们发现，在可持续发展目标生效后，碎片化实际上有所增加。此外，围绕 17 个可持续发展目标以及可持续发展的社会、经济和环境层面的孤岛正在增加。我们发现，在可持续发展目标生效后，碎片化实际上有所增加。此外，围绕 17 个可持续发展目标以及可持续发展的社会、经济和环境层面的孤岛正在增加。
