Party polarization is a general framework that formulated political polarization in terms of political parties.

Description
Party polarization is a very loose framework that simply prescribes studying political polarization in terms of political parties, as opposed to behavioral theory.
These theories generally assume that 'partisanship' or 'extremism' is defined by consistent ideological opinions. The counter-example is that a moderate's opinions are either not strongly held or ideologically-inconsistent (suggesting they are informed by something external).
There are many closely-related fields in the public choice and political philosophy spaces.
- Choice models including:
Median voter theorem, for why polarization is not expected.
Pivotal politics model, for how the appearance of polarization can be achieved without an actual political undercurrent.
Critical theories, e.g. Marxism, have a clear interpretation of both polarization (i.e., history of conflict) and lack of polarization (i.e., elites suppressing consciousness).
Polarization is a topic of study in the field of institutional design.
