There is a heated debate about the social-sustainability implications of infrastructure. We engage this debate by delving into China’s Digital Silk Road (DSR), an important component of China’s infrastructure-centric Belt and Road Initiative (BRI). Optimists and pessimists have offered strong views about the DSR’s social-sustainability implications. Unfortunately, there is a dearth of analytical tools and in-depth studies which can be used to judge their competing arguments. In this article, we address these problems in two ways. First, we advance an original scheme for operationalizing social sustainability. Second, we use our framework to systematically analyze the DSR’s social-sustainability effects in Ethiopia, Malaysia, the United Arab Emirates, and Hungary. Our research indicates that much of the positive and negative commentary about the DSR’s social-sustainability implications is problematic. None of our cases show significant year-to-year changes in political or quality-of-life social-sustainability benchmarks. Indeed, our analysis indicates that analysts must pay close attention to the political and economic context to understand the social-sustainability patterns associated with DSR infrastructure. Finally, it suggests that the social-sustainability implications of DSR infrastructure are dependent on its scale and nature. These findings have ramifications for broader debates about the socioeconomic impact of infrastructure.
