Economic Relational Dynamics: Micro-evolution, Network Structure, and Macro-emergence

July, 2026 • Preprint
Zhang, Jincheng

Traditional economic paradigms have long relied on methodological individualism, modeling market clearing through atomic actors in instantaneous, frictionless, and decontextualized transactions. Howev…

Post-hoc Interpretability of LDA on Hyperspectral Imagery: SHAP Attributions, Counterfactual Topic Flips, and LLM-judge Alignment under Token-Mass-Dispersion Asymmetry

July, 2026 • Preprint
Santibañez-Leal, Felipe

Programme paper P5 of the CAOS_LDA_HSI series. The interpretability claim of LDA-on-HSI rests on the assumption that topic-word distributions are human-readable. This study is restricted to the LDA ba…

Which Wordification Matters? A Nineteen-Recipe Sweep of the Interpretable-Topic-Model Framework on Hyperspectral Imagery

July, 2026 • Preprint
Santibañez-Leal, Felipe

Programme paper P3 of the CAOS_LDA_HSI series. The flagship paper (P1) introduces a twelve-axis evaluation framework for topic models on hyperspectral imagery and instantiates it on a single canonical…

Economic Reversibility Theory: Mechanisms, Constraints, and Systemic Evolution

July, 2026 • Preprint
Zhang, Jincheng

Traditional neoclassical economics heavily borrows from classical mechanics, assuming that economic systems operate around equilibrium states with reversible dynamics. However, real-world economic pro…

Economic Complex Adaptology: Evolutionary Mechanisms of Self-Reorganization in Complex Adaptive Economic Systems under Uncertainty and Dynamic Competition

July, 2026 • Preprint
Zhang, Jincheng

Traditional mainstream economics has long relied on equilibrium analysis and the assumption of rational actors, simplifying the economic system into a mechanical system with deterministic solutions ob…

Economic Boundary Science: Formation, Evolution, and Reshaping of Market, Corporate, National, and Institutional Boundaries

July, 2026 • Preprint
Zhang, Jincheng

Traditional economic frameworks often treat structural entities—such as firms, markets, industries, and nation-states—as static, pre-given analytical containers. However, the rapid advance…

Economic Information Ecology: Evolutionary Mechanisms of Information, Topological Dynamics, and Systemic Resource Allocation

July, 2026 • Preprint
Zhang, Jincheng

This paper systematically constructs the theoretical framework of Economic Information Ecology, delving into how economic information, as a dynamic element with living characteristics, undergoes proce…
