中文摘要：

广西靖西县新靖镇壮语和越南高平省茶岭县广汉村侬语的语言结构特点比较接近，在跨境语言中属于差异较小的类型。二者跨境后之所以还能保持如此高的相似度与跨境历史不长有关，还与两国边民相似的文化、习俗及密切的经济往来有关。

英文摘要：

The structural characteristics of Zhuang language in Xinjing, a town of Jingxi County in Guangxi, and Nung language in Guanghan, a village in Chanling county of Gaoping province in Vietnam, are quite simi-lar and have fewer differences compared with other cross - border languages. The great similarity they sbare are related not only to the fact that they have a short cross - border history but also to the likeness of their cultures and traditions as well as the close economic exchanges between them.
