1. Executive Summary
All six trending keyword clusters sit in a “high heat, high value, mid-to-high competition” zone this cycle. The underlying drivers are remarkably consistent: AI compute infrastructure + new energy (storage / hydrogen / EV) + semiconductor localization.
- Highest heat: Electronic Chemicals and Aerogel — dual policy-and-demand momentum, leading the industry in growth (+13.8% / +17%–25% YoY).
- Fiercest competition: Carbon Fiber and PEEK — mature segments with many players, yet high-end grades remain overseas-dominated, leaving structural substitution windows.
- Best opportunity: High-end localization keywords (electronic-grade PTFE, G5 ultra-pure wet chemicals, silicon-nitride ceramics, T800 carbon fiber) — moderate search competition but high commercial value and policy certainty.
