A recurring conundrum lies at the heart of current anti-trafficking law and policy. Despite enormous efforts by civil society organizations, corporations, and governments to reduce human trafficking in supply chains, and the introduction of legislation in various countries that requires corporations to take active actions in this field, there is wide agreement that, so far, the desired change has not occurred. This article addresses this puzzle through studying the vibrant anti-trafficking activity in the UK construction sector that emerged following the enactment of the UK Modern Slavery Act 2015 (MSA). Applying socio-legal methods, the article unpacks the structural dynamics that shape the implementation of the MSA in the construction sector. We find that the Act exacerbates the imbalanced power relations between firms and anti-trafficking initiatives, positioning the latter as suppliers of modern slavery risk solutions that are dependent on corporate will and funding. The article demonstrates that anti-trafficking initiatives in the construction sector largely follow a “supply chain logic” that significantly limits their capacities to transform corporate behavior. We develop the notion of “anti-trafficking chains” to describe the dynamics of anti-trafficking activities in supply chains and to problematize the entanglement of anti-trafficking actors in supply chain power structure and logic.

反贩运链：分析英国建筑行业透明度立法的影响

当前反人口贩运法律和政策的核心是一个反复出现的难题。尽管民间社会组织、企业和政府为减少供应链中的人口贩运做出了巨大努力，并且各国出台了立法，要求企业在这一领域采取积极行动，但人们普遍认为，到目前为止，期望的目标变化尚未发生。本文通过研究英国 2015 年《现代奴隶制法案》(MSA) 颁布后英国建筑行业开展的充满活力的反人口贩运活动来解决这个难题。本文运用社会法律方法，揭示了影响建筑行业 MSA 实施的结构动态。我们发现，该法案加剧了企业与反人口贩运举措之间的不平衡权力关系，将后者定位为依赖于企业意愿和资金的现代奴隶制风险解决方案的供应商。文章表明，建筑行业的反人口贩运举措在很大程度上遵循“供应链逻辑”，这极大地限制了其改变企业行为的能力。我们提出“反贩运链”的概念来描述供应链中反贩运活动的动态，并解决供应链权力结构和逻辑中反贩运行为体的纠缠问题。
