In recent years, China's developed regions have transferred industries to undeveloped regions. Large numbers of unlicensed or unregistered enterprises are widespread in these undeveloped regions and they are subject to minimal regulation. Current methods for tracing industrial transfers in these areas, based on enterprise registration information or economic surveys, do not work. We have developed an analytical framework combining water fingerprinting and evolutionary analysis to trace the pollution transfer features between water sources. We collected samples in Eastern China (industrial export) and Central China (industrial acceptance) separately from two water systems. Based on the water pollutant fingerprints and evolutionary trees, we traced the pollution transfer associated with industrial transfer between the two areas. The results are consistent with four episodes of industrial transfers over the past decade. Our results also show likely types of the transferred industries - electronics, plastics, and biomedicines - that contribute to the water pollution transfer.
近年来，中国的发达地区向欠发达地区转移产业。大量无照或未注册的企业在这些欠发达地区广泛存在，受到的监管很少。目前，基于企业注册信息或经济调查的追踪这些地区产业转移的方法并不适用。我们开发了一个结合水指纹分析和进化分析的分析框架，以追踪水源之间的污染转移特征。我们分别从两个水系中采集了来自华东（工业出口）和华中（工业接受）的样本。基于水污染指纹和进化树，我们追踪了这两个地区之间与产业转移相关的污染转移。结果与过去十年中的四次产业转移相一致。我们的结果还显示了可能转移的产业类型——电子、塑料和生物医学——这些产业导致了水污染的转移。
