摘　　要：在中部崛起战略实施之后,长江中游城市群的外贸快速增长,但却存在依存度低、外贸份额少、对经济的拉动作用小、发展不均衡等问题。运用显示性比较优势指数和贸易相似性指数分别衡量了31个城市的贸易竞争力和相似度,发现许多城市出口相同产品,且竞争力强的产品主要是资源型、低技术和中技术型产品,城市群内的贸易结构相似程度高且脆弱。这在一定程度上归因于各城市产业结构的相似性。The foreign trade in the middle reaches of the Yangtze River city group has grown rapidly since the implementation of Central China Strategy. However, there are still lots of problems in the trade, such as low dependence, less share, a small role in boosting the economy and uneven development. Measuring the trade competitiveness in 31 cities by using revealed advantage index and trade similarity index to, it is found that many cities export same products, while the products with high competitiveness are mainly those closely related to resources, or those with mediate or low technologies. The trade similarity is very high and fragile in these cities. To a certain extent, it is attributed to the high similarity of the industrial structure of these cities.
