CICC Estimates: AI Exports Boost China's GDP Growth Contribution to 1.1 Percentage Points
Taylor Wilson
CICC's latest research shows China's AI-related exports lifted GDP growth by 1.1 percentage points in Jan–Apr 2026, up sharply from 0.4 points for all of 2025 — yet domestic AI investment is contracting, leaving the growth engine heavily reliant on foreign demand.
How big is a 1.1-point GDP lift?
AI-related exports grew 39.6% year-on-year in Jan–Apr 2026, rising to 22.0% of total exports (up from 18.6% in 2025).
This means → more than one in every five export dollars now comes from AI-linked products, and AI alone accounted for 61% of total export growth.
The export boom also revived electronics-manufacturing investment: fixed-asset spending in the sector swung from -3.2% in 2025 to +5.4%, contributing 58.4% of all manufacturing investment growth.
Which sub-sectors are accelerating fastest?
A-share data for Q1 2026 show the four fastest-growing capex lines: memory +175.1%, optical modules +134.5%, PCB +120.6%, optical fiber +51.2%.
All four accelerated from Q4 2025.
In plain terms = these are the "component suppliers" for AI servers and data centers. The harder US AI capex runs, the fuller China's order books in these segments.
Why is domestic AI investment shrinking instead?
Fixed-asset investment in information technology services fell roughly -7.1% YoY in Jan–May 2026, down from +8.8% in 2025.
The US–China gap is stark: in Q4 2025, US AI infrastructure investment hit $69.2 billion (+81% YoY), versus China's $8.4 billion (-8%). The US figure was 8.2× China's.
This reflects a triple bottleneck: hardware performance gaps, model capability gaps, and financing gaps. Chinese open-source models compete mainly on price; the closed-source market remains dominated by Anthropic, OpenAI, and Google.
Can the export lift last? What are the risks?
Price gains far outpace volume: in Jan–May 2026, electronics export prices rose 21% YoY while volumes grew only 12%. This means → supply expansion has not fully caught up with demand; if prices normalize, the GDP lift will shrink.
Domestic value-add is thin: each unit of electronics exports generates only 0.65 in domestic value-add and 0.35 in imports — the lowest ratio in manufacturing after petroleum refining. In plain terms = the supply chain is long, but the profits and wages that stay onshore are relatively slim.
CICC expects the export chain to sustain high growth as long as US AI capex keeps rising. Consensus forecasts put China's major internet platforms' capex at RMB 285.1 billion in 2026 and RMB 300.9 billion in 2027, up from RMB 212.5 billion in 2025.
What is the key question going forward?
CICC identifies the pivotal test: whether China's AI growth logic can shift from export-driven to domestic-investment-driven.
This means → today's high growth rests on "supplying America's AI boom." If US capex slows or supply-chain policies toward China tighten, this engine stalls.
The signal to watch: when China's cloud-service providers begin ramping their own capex at scale — that is the marker of a genuine switch.
