该研究构建了一个模拟供应链谈判的实验框架，让多个 LLM 代理扮演供应链上下游企业，进行带有私有信息的动态讨价还价。实验的核心在于观察代理是否会利用信息不对称谋取优势，以及它们能否在反复交互中达成接近最优的协议。研究团队测试了多种主流大语言模型，并对比了不同提示策略（如角色扮演、目标设定）对谈判结果的影响。
初步结果显示，LLM 代理普遍能够理解谈判规则并参与多轮议价，但在策略上呈现出显著差异。部分代理倾向于坦诚分享信息以促成合作，而另一些则表现出机会主义倾向，试图隐瞒成本或需求等私有数据来压榨对方利润。值得注意的是，代理的谈判行为高度依赖于模型本身的能力和给定的提示词——更强大的模型在复杂博弈中更能识别并利用信息优势，但也更容易陷入僵局，导致谈判破裂。这一发现对企业在实际部署此类系统时提出了警示：未经精细调校的自主谈判代理，可能因过度追求单方利益而损害长期供应链关系。
此外，研究还探讨了动态定价与联盟形成的问题。在多方参与的供应链场景中，LLM 代理不仅需要与直接对手谈判，还可能动态选择合作伙伴，这与近期另一项关于基于技能的代理 AI 系统中动态联盟与通信定价的研究形成了呼应来源。该研究指出，固定通信架构会限制异构代理系统的效率，而动态定价机制能让代理根据任务需求灵活组队，这与供应链谈判中代理根据实时报价调整合作对象的逻辑一致。这一交叉视角表明，未来的自主代理系统可能需要同时具备谈判、定价与动态组网的能力。
对于企业管理者而言，这项研究的现实意义在于：在将 LLM 代理投入真实采购或销售场景前，必须通过严格的模拟测试评估其谈判风格与风险倾向。原文未提供具体的商业部署案例，但实验框架本身为风险评估提供了方法论参考。研究者强调，当前的 LLM 代理尚不能完全可靠地处理涉及重大利益的商业谈判，人类监督与干预机制在可预见的未来仍不可或缺。

arXiv:2608.07538v1 Announce Type: new Abstract: As LLM agents move from decision support to autonomous procurement, firms need to know whether delegated negotiators create value, divide it predictably, and avoid money-losing contracts. We study this in a canonical supply chain bargaining problem: a buyer with private demand information negotiates a quantity-payment contract with an uninformed seller. We benchmark nine LLMs from OpenAI, Google, and Alibaba against a validated Perfect Bayesian Equilibrium across 9,840 LLM-to-LLM negotiations. First, capability governs value creation. Agents agree in 98.9% of negotiations and capture 95.4% of first-best surplus undiscounted, but average 2.98 rounds against the benchmark's 1.25, and this delay erodes 21-34% of surplus. Capability also governs reliability: baseline models accept individually irrational contracts in 19.2% of cases, versus 0.0-0.6% at mid-tier and flagship, making automated profit verification the binding guardrail below that threshold. Second, surplus capture is relational. Provider identity predicts who captures surplus better than capability rank: self-play buyer shares average 40% for OpenAI, 50% for Google, and 70% for Alibaba's Qwen, an ordering that survives restricted communication and no discounting. Reversing which provider sells moves the division by 7-18 percentage points, and the capable Qwen flagship is the weakest cross-family seller: vendor choice is a first-order distributional decision. Third, the prompt is a strategic lever. Delegation separates the principal's economic patience from the agent's prompted strategic patience, a free deployment choice that is the single strongest driver of surplus division (90% of explained variance). Together these establish an equilibrium-referenced audit of AI agents along three dimensions: discounted efficiency, distributional profile, and operational reliability.
