Social capital, environmental justice and carcinogenic waste releases: US county-level evidence, 1998–2019
研究了社会资本如何解释企业致癌物排放的区域不平等，发现社会资本通过促进信息共享和协调减少排放，但依赖污染企业提供经济机会的县效果减弱。
We examine the role of social capital in explaining the highly unequal regional distribution of firms’ carcinogenic releases. Our model predicts that social capital, by enabling information-sharing and coordination among community members, decreases carcinogenic releases. Our analysis, based on the US county-level releases derived from around 2 million chemical-facility-level reports during the period 1998–2019 and the instrumental variables approach, confirms our prediction. However, the impact is reduced when counties rely on waste-releasing firms for economic opportunities. An important policy implication of our study is that the efficacy of initiatives to alleviate environmental injustice is likely to depend on communities’ social capital.
