entity framework

Hello,

We analyzed the history and development of ...... Group, starting from year .... to the present. The analysis covered the background of the group's establishment, key shareholders/partners involved, the group's development over the years, and events relevant to the subject ...
In addition, emphasis will be placed on the analysis of the .... Group's structure, which has been characterized by aggressive tax planning and a complex that shifted between different jurisdictions, with the group's holding entity migrating from its initial establishment under country X jurisdiction, to the ... Islands, and ultimately domiciled in country Y.

Is there another way to say "entity framework" in this context, so it will be clearer to me?

Thanks in advance.

'Entity' here likely means 'organisation', some body of people with legal existence who do something. This 'entity' is who manages the group. The group is a subsidiary of the entity's. In other words, the entity is the group's parent or holding company. 'Framework' means structure, underlying form, fundamental base. The framework of a company, business, or organisation is the blueprint for how it manages itself, how it's structured, who does what and how what is done is decided, how information gets around, and everything relating to the structure of this 'entity' (parent/holding company, in this case).

I should note that 'entity' just means organisation. I just believe it refers to the parent or holding company in this context.

They might also be referring to the structure of the group itself, rather than to that of the holding company, and saying that the framework of the group was complex or well-made enough to withstand the holding company's migration between jurisdictions without issue. In that case, 'entity' in 'entity framework' would refer to the group, and 'framework' would refer to the structure of the group itself. Both of these are likely interpretations.

Perhaps someone else could help narrow it down.

Where did you see this, maayani?

We ask you to name the source of anything you didn't write yourself.

It's a report which I need to translate.

Here it means the way the different companies are organised. For example, YouTube is owned by Google LLC which is itself owned by Alphabet Inc. It is relatively simple to draw an organisation chart and establish who really owns the company from published information. But your text refers to a corporate organisation chart which is deliberately complex and difficult to identify.
Entity = something which has a legal existence, such as a corporation, association or partnership.
Framework (in this example) = organisation - how various separate but linked entities are related to each other.
