I'm reading this
[article](https://www3.nhk.or.jp/news/easy/k10011528251000/k10011528251000.html)
about new technologies that are getting introduced to monitor employees.

I am unsure about the following sentence. I do not understand why there isn't
a particle or something like it between the など and the 230. Is this a typo or
what is intended here?

> ソフトウェアをつくっている会社 **など２３０** の会社が新しい技術を紹介しています
>
> My Translation: 230 companies are introducing new technologies, where these
> companies and similar places are producing software

question
grammar particles particle-など
Missing particle after など in article about new technologies to monitor employees
> 「ソフトウェアをつくっている会社{かいしゃ} **など２３０** の会社が新{あたら}しい技術{ぎじゅつ}を紹介{しょうかい}しています。」

Conclusion first. There is nothing missing between 「など」 and 「２３０の会社」. That is
simply perfect grammar in formal speech.

If one **_had to_** insert a particle in between that made sense, that
particle would be 「の」. It would, however, be slightly wordy because there will
be another 「の」 coming soon in 「２３０の会社」. It would also make the sentence sound
unnecessarily informal as well.

「A など B」 indicates that A is an example of B.

That is why your translation is slightly off. Not all of the 230 participating
companies are software houses. There are other types of companies present as
well even though the sentence does not mention what kinds of companies they
are. So, the math here is:

The number of software houses + X = 230

X is the number of other types of companies participating.

answer
In [_Nominal apposition in
Japanese_](https://www.questia.com/library/journal/1G1-132534929/nominal-
apposition-in-japanese) (2004), Rumiko Sode calls this など an "exemplifier",
and considers this construction a type of apposition in which one noun phrase
restates a subset of another.

Basically, you've got two noun phrases next to each other:

> N1などN2

Which expresses that N1 is included within N2. In other words, N1 is a
restatement of _part of_ N2. It could be translated in various ways depending
on context. For example:

> 秋田犬など大型犬に最近人気がある。  
>  Recently, Akitas and other large-breed dogs are becoming popular.

Here, 大型犬 includes 秋田犬 as a subset or an example, and the noun phrases are
linked together by など. Nothing is missing between them.

Likewise, in your example:

> ソフトウェアをつくっている会社など２３０の会社が新しい技術を紹介しています。

The larger set is ２３０の会社, and ソフトウェアをつくっている会社 is some subset of those 230
companies.
