“内销”常见的英文表达是 “domestic sales” 或 “sales on the domestic market”。
“domestic sales” 简洁直接,在商业语境中经常使用,例如:The company has seen a significant increase in domestic sales this quarter.(该公司本季度内销有了显著增长。)
“sales on the domestic market” 表述稍详细一些,突出了是在国内市场进行销售,比如:Our focus this year is to expand sales on the domestic market.(我们今年的重点是拓展国内市场销售。)
