New Era Economic Law

This paper establishes the theoretical framework of the School of Legal-Economic Isomorphism, arguing that law and economy exist not in a relationship of mutual influence, but in an isomorphic relationship of definition and being defined. Drawing on comparative historical analysis spanning from the Code of Hammurabi and Fuxi’s trigrams to the Roosevelt New Deal, the study distills three sub-laws of civilizational evolution: the Law of Productivity Step-Functions, the Law of Legal Reconstruction, and the Law of Alignment Synchronization. It diagnoses the persistent global economic stagnation of the past two decades as a “Temporal Misalignment” between industrial-age legal frameworks and digital-age productive forces. The paper introduces core analytical concepts—Digital Public Infrastructure, Digital Easement, Digital Rent, and Rentier Capitalism—to demonstrate that large digital platforms function not as private stores but as digital land extracting feudal-like rents. The study proposes a constitutional-level institutional engineering program for the digital age, including the publicization of platforms, the prohibition of digital rent, and the establishment of data public ownership, while critically transcending existing schools of Law and Economics, Institutional Economics, and Marxist Political Economy.
