SAE 经济学系列
SAE Economics Series
从维度序列理论（SAE框架）重新诊断理性人假设：效用最大化是理性的第一层，不是全部。 底线守护、在底线间创造新方案、识别不可涵育——是另外三层，同样是理性，只是经济学的语言装不下它们。 本系列六篇论文从诊断出发，经由微观机制、群体动力学，到相变数学骨架和AI时代的竞争分析。
Rediagnosing the rational agent assumption from Dimensional Sequence Theory (SAE framework): utility maximization is the first layer of rationality, not all of it. Bottom-line defense, creating new solutions between bottom lines, recognizing the un-culturable — these are three more layers, equally rational, just beyond what economics' language can hold. Six essays, from diagnosis through micro-mechanism, collective dynamics, phase-transition mathematics, and AI-era competitive analysis.
理性不止一层：效用函数、不确定性监控、底线守护、双主体协商——四层，不是一层。
底线不是天生的，也不是外部植入的。碰撞产生感知，竞争产生原则。15DD是14DD的赢家，不是圣人。
桥的另一端空着时：涵育，或识别不可涵育。No deal是合法输出，假C才是真正的损失。
12DD、14DD、15DD混在同一个市场里。声誉不是形象管理，15DD的聚集不需要宣言——它在重复博弈中自发发生。
市场转型有三阶段：萌芽、翻转、确立。χ ∈ [2.75, 4.01]。形状是ρ-守恒原理的必然，速度是人类的选择。
手段王国有五个结构性优势，在低η世界里全部有效。AI是主体性放大器：15DD+AI的收益是指数级的，12DD+AI是线性的。
Rationality has four layers: utility maximization, uncertainty monitoring, bottom-line defense, and bilateral negotiation — four, not one.
Bottom lines aren't innate or externally installed. Collision produces perception, competition produces principles. 15DD is 14DD's winner, not its saint.
When the other end of the bridge is empty: nurture, or recognize the un-culturable. No-deal is legitimate; fake C is the real loss.
12DD, 14DD, 15DD coexist. Reputation isn't image management. 15DD clustering needs no manifesto — it happens spontaneously in repeated interaction.
Market transformation has three stages: sprouting, flipping, consolidation. χ ∈ [2.75, 4.01]. Shape is structural necessity; speed is human choice.
Kingdom of Means has five structural advantages, all effective in a low-η world. AI amplifies subjectivity: 15DD+AI returns are exponential, 12DD+AI returns are linear.
