经济行为量： 基于最小作用量原理的全球经济链-- 兼论经济规律和中国原创经济理论
Economic Behavior Action: Based on the least action principle’s Global Economic Chain---- An exploration of economic law and China’s original economic theory
[目的]
揭示对“全球经济链”的误判和GDP的局限性，提出经济行为动态递进新范式，探究经济发展的根本规律和中国原创经济行为量理论的实证和应用。
[方法]
基于WTO、UN Comtrade、IDC等全球宏观经济数据库，采用系统分析与变分建模相结合的方法，构建以“动态递进循环经济行为”的新范式，提出以“经济行为量” A= ∫▒(T-V)dt为核心的综合经济规律测度指标。
[结果]
研究表明，“经济行为量”能有效捕捉产出动能（T）与购买势能（V）之间的时滞与偏差，克服GDP核算的静态性与割裂性，为评估经济效率提供可计算、可模拟的新工具。实证初步显示，中国经济当前处于“T > V”状态，即产出动能高于购买势能，需着力提升消费能级。
[局限]
尽管初步实证支持了“经济行为量”的有效性，但是其广泛应用仍面临挑战，如数据颗粒度不足、产出动能（T）与购买势能（V）的精确分离存在操作难度、在不同经济体间可比性有待验证。当前范式侧重宏观行为动力学建模，未来研究可以纳入制度、政策等因素影响，提升模型的完善性。
[结论]
本研究提出的“经济行为量”范式，不仅突破了传统经济测度的结构性缺陷，更揭示了现代经济系统演化的根本规律——即产出动能（T）与购买势能（V）的耦合互动趋向于使经济行为量A取驻值（δA=0）。这一发现为中国原创经济理论的发展提供了坚实的数学物理基础，也为高质量发展政策的精准制定提供了全新的量化依据。

[Objective]
This study aims to reveal the misjudgments of the "Global Economic Chain," the limitations of GDP indicators. It proposes a new paradigm—Dynamic Progressive Circular Economic Action (DPCEA)—and explores the fundamental law of economic development, alongside the empirical application of an original Chinese economic theory centered on “Economic Behavior Action.
[Method]
Leveraging global macroeconomic databases (e.g., WTO, UN Comtrade, IDC), this research employs a methodology that integrates systems analysis with variational modeling. It constructs the DPCEA framework, introducing the "Economic Behavior Action" A= ∫▒(T-V)dt as a core metric for comprehensive economic assessment. This metric is designed to capture the closed-loop dynamics of economic behaviors, moving beyond the static and fragmented logic of traditional accounting-based indicators like GDP and Total Factor Productivity (TFP).
[Result]
Economic Behavior Volume A is established as a holistic alternative to GDP, effectively characterizing the dynamic coupling cycle between societal productive capacity (P) and purchasing power (B). By quantifying the time lag and deviation between transaction flow (T) and value realization (V), it overcomes the unidirectional and disaggregated nature of traditional metrics, providing a computable, simulatable, and process-oriented tool for dynamic efficiency assessment and structural diagnosis of economic systems.
[Limitation]
Although preliminary empirical evidence supports the validity of A, its widespread application faces challenges, including insufficient data granularity, operational difficulties in precisely separating T and V, and limited cross-national comparability. The current paradigm focuses on macro-level behavioral dynamics and does not yet incorporate the moderating effects of institutional frameworks, policy interventions, or regional heterogeneity.
[Conclusion]
This study establishes the DPCEA paradigm and the Economic Behavior Action A as a breakthrough in overcoming the structural flaws of traditional economic measurement. It formulates, empirically validates, and applies an original Chinese theory of economic behavior quantification—offering a new foundation for rethinking economic dynamics, policy evaluation, and high-quality development in the era of deeply integrated global economic chains.
This metric reflects the dynamic coupling between societal productive capacity (P) and purchasing power (B), offering a calculable, simulatable, and controllable pathway for high-quality development.
