How to understand the relationship between national types and national forms, and what national forms are there in real politics?

The relationship between state type and state form is the relationship between state system and regime, which are closely linked and unified. Any state system must realize the task of the ruling class through a certain form of government. State system is content, state system is form, state system determines state system, state system adapts to state system, shows state system, serves state system and consolidates state system. From the perspective of change, compared with political power, the state system is often relatively stable. However, we can't mechanically understand the state system as a simple correspondence. Under the influence of historical conditions, cultural traditions, national characteristics, domestic class power contrast and international environment, the same type of state system can also take different forms of government. The usual regimes are: captive, collusive, predatory, failed, dependent, autonomous and instrumental.
