gōngsī zhèngzài diàochá zhège wèntí.

The basic order is:

Subject + 正在 + Verb + Object

So here:

• 公司 = the company
• 正在 = is currently / is in the middle of
• 调查 = investigate
• 这个问题 = this issue / this problem

So the sentence structure is very close to English:

The company is investigating this issue.

A very literal breakdown would be:

Company + currently + investigate + this problem

正在 shows that an action is in progress right now. It is similar to the English be + -ing form.

So:

• 调查这个问题 = investigate this issue
• 正在调查这个问题 = be investigating this issue right now

It emphasizes that the investigation is ongoing at the present time.

Both can mark an ongoing action, but 正在 usually sounds a bit more explicit or formal.

For example:

• 公司在调查这个问题。
• 公司正在调查这个问题。

Both mean The company is investigating this issue, but 正在 puts slightly more focus on the action being underway right now.

Very roughly:

• 在 + verb = be doing
• 正在 + verb = be in the middle of doing / be currently doing

In everyday speech, both are common.

Yes. You can say:

公司调查这个问题。

This simply means The company investigates / is investigating this issue depending on context.

Without 正在, the sentence does not emphasize the ongoing nature as strongly. Chinese often relies on context, so leaving it out is very normal if the situation already makes the timing clear.

Mandarin does not have articles like a, an, and the.

So 公司 can mean:

• a company
• the company
• sometimes just company / companies

The exact meaning depends on context.

In this sentence, English naturally translates it as the company or the company is investigating this issue, but Chinese does not need a separate word for the.

In standard Mandarin, when you use 这 or 那 before a noun, you usually need a measure word.

The pattern is:

这 / 那 + measure word + noun

So:

• 这 + 个 + 问题
• 这个问题 = this issue

Here, 个 is the measure word. It is a very common general measure word.

Saying 这问题 may be heard in casual speech in some contexts, but 这个问题 is the standard form learners should use.

Yes, exactly.

In 这个问题:

• 这 = this
• 个 = measure word
• 问题 = problem / issue / question

So 这个 literally means this + measure word, and then it modifies the noun:

这个问题 = this problem / this issue / this question

Because Chinese noun phrases place demonstratives before the noun.

The normal order is:

Demonstrative + Measure Word + Noun

So:

• 这个问题 = this issue
• 那个公司 = that company

This is different from English only in that Chinese requires a measure word in between.

Compare:

• English: this issue
• Chinese: this + measure word + issue

调查 means to investigate, to look into, or to conduct an inquiry.

It usually refers to a fairly deliberate or organized investigation, such as by a company, government, police, or researchers.

It is not the same as simply asking a question.

For example:

• 调查这个问题 = investigate this issue
• 问这个问题 = ask this question

So in this sentence, the company is not just asking about the issue; it is looking into it.

That is a very common feature of 问题.

Depending on context, 问题 can mean:

• question
• problem
• issue

Examples:

• 我有一个问题。 = I have a question.
• 这个问题很严重。 = This problem is serious.
• 公司正在调查这个问题。 = The company is investigating this issue.

In your sentence, problem or issue is the natural meaning, because companies usually investigate issues/problems, not investigate questions in the classroom sense.

It is commonly pronounced zhè ge.

A useful point for learners: the 个 in 这个 is often said with a neutral tone.

So:

• 这 = zhè (4th tone)
• 个 = ge (neutral tone)

That is why it is often written in pinyin as zhège, but in actual pronunciation the second syllable is usually light:

zhè ge

Yes, absolutely.

公司在调查这个问题 and 公司正在调查这个问题 are both correct.

The version with 正在 sounds a bit more explicit about the action being ongoing. The version with just 在 is also very natural.

So:

• 公司在调查这个问题。
• 公司正在调查这个问题。

Both are good sentences.

Usually, 正在 goes before the verb:

• 公司正在调查这个问题。

That is the normal placement.

You generally should not put it after the verb in this sentence. For example, 公司调查正在这个问题 is incorrect.

If there is a helper verb or a longer structure, placement can sometimes vary a little, but for a sentence like this, the safe pattern is:

Subject + 正在 + Verb + Object

It sounds neutral to somewhat formal.

Why?

• 公司 is neutral
• 正在 is common but slightly more explicit than casual speech sometimes needs
• 调查 is a more formal verb than something very conversational

So this sentence would fit well in:

• news reports
• business contexts
• written Chinese
• normal spoken Mandarin in a serious context

It does not sound strange in speech, but it is a bit more formal than very casual everyday chat.
