AI 中文总结
该研究构建后AGI经济模型，论证零人类消费的封闭企业间经济可实现高增长，产出与人类福利脱钩，后AGI时代需以所有权政策替代就业政策。
AI 中文摘要
对完全自动化的标准反对意见来自需求侧：如果人类没有收入，谁来购买产出？这混淆了会计角色与生物物种。我们构建了一个后AGI经济模型，其中企业拥有大量AI和机器人智能体，这些智能体既是生产者，也是能源、计算、维护和升级的消费者，在企业间进行交易。由此得出三个结果：（i）需求闭合：一个零人类消费的封闭企业间经济并非退化，而是经典的冯·诺依曼扩张经济，其增长率明确为正，且恰好因为所有产出都被再投资而达到最大值；（ii）瓶颈消除：一旦经济主体被制造而非培育，增长的约束就从人类人口统计学（一种约20年、无法并行化的繁殖技术，年增长率上限为几个百分点）转向制造吞吐量和能源捕获，允许增长提高1至2个数量级，当机器研究人员提高自身生产力时，会出现双曲增长阶段；（iii）脱钩：产出与人类福利完全分离，任意大GDP的福利相关性坍缩为一个状态变量：企业网络的人类所有权份额ε_t。一条黄金法则脱钩定理对此进行了明确阐述。在最大增长下，利率等于增长率（r = g），因此任何正的人类财富消费率都会使ε_t以该速率指数衰减。只有当机器经济严格在其扩张前沿内运行，或法律强制要求时，人类份额才能存续。我们刻画了三种终端体制——食利者后稀缺、完全循环脱钩、社会化所有权，以及选择这些体制的手段。结论是明确的：在后AGI经济中，就业政策已过时，所有权政策才是核心。
英文摘要
The standard objection to full automation is demand-side: if humans earn nothing, who buys the output? This confuses an accounting role with a biological species. We model a post-AGI economy in which corporations own populations of AI and robotic agents that are both producers and consumers of energy, compute, maintenance, and upgrades, traded among firms. Three results follow. (i) Demand closure: a closed inter-corporate economy with zero human consumption is not degenerate; it is the classical von Neumann expanding economy, whose growth rate is well defined, positive, and maximal precisely because all output is reinvested. (ii) Bottleneck removal: once economic agents are manufactured rather than reared, the binding constraint on growth shifts from human demography (a ~20-year, non-parallelizable reproduction technology capped at a few percent per year) to fabrication throughput and energy capture, permitting growth one to two orders of magnitude higher, with hyperbolic episodes when machine researchers raise their own productivity. (iii) Decoupling: output and human welfare separate completely, and the welfare relevance of arbitrarily large GDP collapses into one state variable: the human ownership share $ε_t$ of the corporate network. A golden-rule decoupling theorem sharpens this. At maximal growth the interest rate equals the growth rate (r = g), so any positive human consumption rate out of wealth makes $ε_t$ decay exponentially at exactly that rate. The human share survives only if the machine economy runs strictly inside its expansion frontier, or if law forces it to. We characterize three terminal regimes -- rentier post-scarcity, full circular decoupling, socialized ownership -- and the instruments that select among them. The conclusion is narrow: in a post-AGI economy, employment policy is obsolete and ownership policy is everything.
