内容简介
Abstract:
China’s environmental regulators have
sought to reduce the Yangtze River’s water pollution. We document that this
regulatory effort has had two unintended consequences. First, the gulation’s
spatial differential stringency has displaced economic activity upstream. As
polluting activity agglomerates upstream, more Pigouvian damage is caused
downstream. Second, the regulation has focused on reducing one dimension of
water pollution called chemical oxygen demand (COD). Thus, local officials face
weak incentives to engage in costly effort to reduce other non-targeted but
more harmful water pollutants such as petroleum, lead, mercury, and phenol.
摘要：
中国的环境监管机构已经在设法减少长江的水污染。我们发现这一监管努力产生了两个意想不到的后果。首先，空间分化的规制强度已经改变了上游的经济活动。随着污染活动在上游的聚集，下游遭受了更多的庇古损失。其次，规制的重点在于减少化学需氧量（COD），而这只是水污染的一个维度。因此，地方官员缺乏激励去付出高成本的努力来减少其他非目标的但是更有害的水污染物，比如石油、铅、汞和苯酚。
