21st Century New Jurisprudence A System of Institutional Evolution Chapter I: The Essence of Law and the Definition of True Jurisprudence Chapter II: Foundations of Jurisprudence — The Co-Evolutionary Theory of Procedural and Substantive Justice Chapter III: Mechanisms for Integrating Jurisprudence with Social Governance Chapter IV: How Legal Rules Transform the National Economy Chapter V: Unifying the Art of Reform with Legal Provisions This system proposes that law is fundamentally a teleological order whose legitimacy derives not from procedural completeness but from its capacity to realize substantive justice — the protection of life, liberty, and human flourishing. It diagnoses contemporary institutions through the "diagnosis-treatment-construction" triad, identifying structural violence embedded in healthcare monopolies, cryptocurrency markets, and sports governance as pathologies that invert means into ends. Procedural justice, left uncoupled from substantive purpose, self-accelerates into illegitimacy through cumulative distortion, feedback failure, and legitimacy erosion — a pattern confirmed by comparative history from Qin to Rome to modern America. The remedy is institutional self-calibration: sunset review, independent fact-finding, audit-based compensation, and rapid correction channels that keep law tethered to its teleological anchor. Reform proceeds through a four-phase roadmap balancing synchronicity (preventing regulatory arbitrage) with sequential constraint (avoiding systemic overload), guided by 31 diagnostic conditions that tie every provision to a specific pathology and cure. The underlying logic unifies healthcare's five therapeutic mechanisms, cryptocurrency's six-dimensional governance framework, and cross-border regulatory alignment under the "shared loss principle" — ensuring risk-creators bear costs, not society. Law's ultimate aim is not to protect capital's freedom but to expand individuals' substantive freedom, making the economy serve comprehensive human development. In an era of AI adjudication, digital assets, and ecological crisis, this jurisprudence demonstrates that institutional evolution — the continuous rebuilding of the causal chain between rules and their purposes — is the only reliable path to steering civilization toward life, liberty, and prosperity.

Abstract With rapid urbanization and expanding infrastructure, construction contract disputes are increasing in volume and complexity, challenging traditional adjudication. This study proposes a domain-specific legal artificial intelligence (AI) system for construction contract disputes via hybrid knowledge integration based on the retrieval-augmented generation (RAG) paradigm, integrating five core legal texts and 500 adjudication cases within a dual-engine architecture. The knowledge base encodes legal concepts, relations, and rules to enable structured semantic inference. The DeepSeek-R1 reasoning engine analyzes case facts and legal logic via constrained generation, while the BGE-M3 retrieval module matches legal provisions and precedents using multivector indexing. A tripartite evaluation framework—semantic similarity, legal provision citation accuracy, and issue prediction F1 score—validates system performance. The hybrid knowledge model outperforms single-source models, achieving scores of 0.736, 0.952, and 0.937, respectively, while significantly reducing judicial document generation time. This study offers a theoretical and empirical basis for legal AI in Chinese construction disputes, demonstrating how integrating diverse legal knowledge enhances intelligent judicial assistance within China’s jurisdiction. It also provides a scalable methodological reference for the advancement of smart justice, with explicit recognition of its current jurisdictional limitations.
