瓶颈

• ピンイン: píng jǐng
• 漢字の分解: 瓶 = 并 + 瓦 (joined + pottery — a ceramic container); 颈 = 巠 + 页 (vein-like pattern + head — the neck)

意味

ボトルネック（進行や処理量を制限する要因）

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.

例文

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。
2. 工厂通过引进自动化生产线，成功消除了长期制约产能提升的包装环节瓶颈，产效大幅提升。
3. 对许多有志于突破职业瓶颈的中层管理者而言，跨行业学习和系统性思维训练是常见的自我提升路径。

トーン: neutral

正しい言い方

• 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.)

避ける言い方

• 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

起源と歴史

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