The productivity distributions of law have many problems nowadays, such as the uneven distributions in geographical regions, subjects and ages.The restriction factors of imbalances mainly include material-centric factors and human-centric factors.The interaction between these two factors can form four modes:strong-strong alliance, strong-weak mixture, weak-strong combination, double weak union.The four modes correspond to positive-sum game model, neutral-sum game model and zero-sum game model.To get out of the productivity dilemma of law, lessons must be drawn from systematic thinking.Growth pole theory and academic matrix theory provide theoretical supports for it.
