民营中小企业怎么翻译成英文?

small and medium-sized private (或private-owned都可以）enterprises

如果是个体经营的则是“self-employed households”但是“a small private business”特指中国内地民营小企业

民营中小企业用英文翻译如下：
Privately operated mid- and small-scale enterprise。

Private-owned enterprises of small &medium scale

small or medium sized private enterprise

Privately operated mid- and small-scale enterprise.
