讲座内容摘要：

Abstract: Nonstandard work (NSW) — encompassing flexible, informal, and dispatched employment — is reshaping labor markets around the world. Amid the escalating US-China trade tensions, we analyze millions of Chinese online job postings to uncover NSW's role as a critical adjustment mechanism during economic disruptions. Our findings reveal that NSW is predominantly concentrated in economically developed cities and sectors such as real estate, transportation, and culture, and is heavily oriented toward low-skilled tasks. Unlike standard employment, NSW exhibits resilience to tariff-induced shocks. As US tariffs constrain job opportunities and suppress wages for standard workers, firms increasingly turn to NSW, especially favoring less experienced and dispatched roles, while maintaining wage levels. China’s retaliatory tariffs further intensify the demand for NSW, resulting in a significant rise in job postings and wages. Through a simple trade model, we demonstrate how NSW influences responses to external shocks and examine the welfare implications, underscoring the growing importance of NSW in stabilizing labor markets amid global trade disruptions.

非标准工作（NSW），包括灵活就业、非正式工作和派遣工作，正在重塑全球劳动市场。在日益加剧的中美贸易摩擦背景下，我们分析了数百万条中国在线职位信息，以揭示NSW在经济动荡期间作为重要调节机制的作用。研究结果显示，NSW主要集中在经济发达的城市和行业，如房地产、交通运输和文化领域，并且以低技能任务为主。与标准就业不同，NSW在应对关税冲击时表现出较强的韧性。当美国关税限制了标准工人的就业机会并压低工资时，企业越来越多地转向NSW，尤其倾向于招聘经验较少和派遣性质的岗位，同时保持薪资水平。中国的反制关税进一步加剧了对NSW的需求，导致岗位数量和工资水平显著上升。通过一个简单的贸易模型，我们展示了NSW如何影响企业对外部冲击的反应，并探讨了其对福利的影响，强调了NSW在全球贸易动荡中稳定劳动市场的重要性。
