本文以我国工业化水平相对较高的鲆鱼养殖业为研究对象，采用区位熵和空间基尼系数法，对2003―2012 年沿海地区鲆鱼养殖集聚程度进行了测算，结果表明我国鲆鱼养殖业表现出较明显的产业集聚特征，主要集聚于山东省和辽宁省。其中山东省集聚程度始终最高，但在逐步下降，辽宁省则逐步提升。研究指出：中国的鲆鱼养殖之所以出现产业集聚，尽管也有资源禀赋、需求拉动等因素影响，但技术创新和产业政策在其间发挥了尤其重要的作用；要继续推动鲆鲽类产业集群的发展，必须以产业政策为引导、以技术创新为重点，同时打造产业文化，创造市场需求，引领产业发展。

These studies were focused on second and third industry, cluster of aquaculture was rarely explored and reported. Using Location Quotient and Spatial Gini Coefficient methods, the cluster of lefteye flounder Farming Industry of China from 2003 to 2012 was estimated and in this paper. The results showed that industrial cluster does exist in flounder aquaculture of China, mainly clustered in Shang Dong and Liao Ning. Its cluster degree in Shang Dong has been highest since the development of this industry, but it has decreased since 2005. Contrarily, its cluster degree in Liao Ning has kept on increasing. This study suggest that: the industry cluster of flounder aquaculture is influenced not only by resource endowments and demand factors, but also by technological innovation and industrial policies; if one want to promote the industrial clusters of this industry, industrial policy and technological innovation should be paid more attention, at the same time, industrial culture, which can help to create demand and lead the development of this industry, should be forged.
