• 병음: píng jǐng
• 한자 분석: 瓶 = 并 + 瓦 (joined + pottery — a ceramic container); 颈 = 巠 + 页 (vein-like pattern + head — the neck)

뜻

병목(현상); 진행이나 처리량을 제한하는 제약

Used in production/supply chains (生产瓶颈), technology (技术瓶颈), traffic (交通瓶颈), and personal development (成长瓶颈). 突破瓶颈 = to break through a bottleneck. Ubiquitous in business and project management.

예문

1. 公司目前最大的发展瓶颈在于核心技术人才的严重匮乏，这一问题若不解决将制约整体业务的持续扩张。

맥락: business, technology, production, career

어조: neutral

올바른 표현

• 在整个供应链优化过程中，识别和消除关键瓶颈节点比单纯提升各环节局部效率更能带来整体性能的质变。(In the entire supply chain optimisation process, identifying and eliminating key bottleneck nodes brings about a qualitative transformation in overall performance more effectively than simply improving the local efficiency of individual links.)
• 当前人工智能发展的主要瓶颈已从算法层面转移至高质量标注数据的获取和算力基础设施的持续扩建。(The primary bottleneck of current artificial intelligence development has shifted from the algorithmic level to the acquisition of high-quality labelled data and the continuous expansion of computing infrastructure.)

피해야 할 표현

• 瓶颈 specifically means a constraint that limits throughput or progress — do not use it to mean simply 'difficult' or 'challenging'; if no flow/progress is being constrained, use 障碍 or 困难 instead

기원과 역사

瓶 (bottle — 并 + 瓦 pottery) + 颈 (neck — 巠 + 页 head). Metaphor borrowed from fluid dynamics: the narrow neck restricts flow.
