zhè jiā gōngsī yǒu hěnduō fúlì.

Here, 家 is not the noun meaning home or family. It is a measure word / classifier used for certain businesses and establishments, such as companies, stores, restaurants, and hotels.

So 这家公司 breaks down like this:

• 这 = this
• 家 = classifier for businesses
• 公司 = company

Together: this company.

People would probably understand 这个公司, but 这家公司 is the more natural and standard way to say this company.

In Mandarin, when a noun uses a classifier, the usual pattern is:

demonstrative + classifier + noun

So:

• 这家公司 = natural
• 这个公司 = understandable, but less idiomatic

In this sentence, 福利 means employee benefits, perks, or welfare benefits offered by a company.

Depending on context, 福利 can include things like:

• health insurance
• paid leave
• bonuses
• meal subsidies
• housing allowances

So in a company context, it usually means job benefits, not just a vague idea of well-being.

有 means to have or there is/are. In this sentence, it shows that the company has many benefits.

So:

• 这家公司有很多福利 = This company has many benefits

You would not use 是 here, because 是 links two nouns or noun phrases, like A is B. This sentence is about possession, so 有 is the correct verb.

Even though 很 often means very, in 很多 the two characters work together as a set phrase meaning many or a lot of.

So you should learn 很多 as one common expression:

• 很多人 = many people
• 很多问题 = many questions
• 很多福利 = many benefits

It does not usually need to be translated as very many.

After 很多, a measure word is often not needed when you are talking about nouns in a general way.

So:

• 很多福利 = many benefits

This is normal Mandarin.

If you want to count types or kinds more explicitly, you might say:

• 很多种福利 = many kinds of benefits

But in the original sentence, 很多福利 sounds natural and complete.

Because 很多 can directly modify a noun without 的.

So:

• 很多福利 = natural
• 很多的福利 = possible, but less common here and often feels a bit more formal or emphatic

In everyday Mandarin, 很多 + noun is the usual pattern.

Chinese nouns usually do not change form for singular and plural the way English nouns do.

So 福利 can mean:

• benefit
• benefits

The context tells you which meaning is intended. In this sentence, because of 很多, it clearly means benefits.

The sentence follows a very common Mandarin pattern:

demonstrative + classifier + noun + 有 + quantity + noun

So:

• 这家公司 = this company
• 有 = has
• 很多福利 = many benefits

This is quite close to English word order:

This company has many benefits.

Normally, it would be written without spaces:

这家公司有很多福利。

The spaces in learning materials are just there to help you see the parts more clearly. In standard Chinese writing, words are not usually separated by spaces.

Yes. 这家公司福利很多 is also natural and means essentially the same thing.

The difference is mainly in structure:

• 这家公司有很多福利 = This company has many benefits.
• 这家公司福利很多 = As for this company, its benefits are many.

The original sentence with 有 is very straightforward and beginner-friendly, while 福利很多 is also common in natural speech.
