This paper employs the Political Philosophy Cohesion Model from the "Productive Political Philosophy" framework as a universal evaluative yardstick to conduct a unified structural assessment of five major modern intellectual systems: Liberalism, Marxist Historical Materialism, New Institutional Economics, Postmodernism, and Modernization Theory. The Cohesion Model integrates functional scores across three dimensions—Value completeness (V), Methodology completeness (M), and Tool completeness (Tₜool) —with an assessment of Matrix Homogeneity (ρ), forming a comprehensive formula for political-philosophical system integrity: Ω = ρ × min (V, M, Tₜool). The paper systematically analyzes the underlying axioms, three-dimensional functions, homogeneity, deficiency types, and completion ceilings of each system. It demonstrates that all modern mainstream systems exhibit structural incompleteness, providing a general analytical paradigm for cross-school intellectual dialogue and political-philosophical system construction. Keywords: Political Philosophy Cohesion Model; Matrix Homogeneity; Modern Intellectual Systems; Intellectual History Assessment; Completeness Criteria; Dynamic Deficiency; Static Deficiency.
