Why it matters now: The global industrial automation supply chain is undergoing a once-in-a-generation realignment. When McKinsey's most senior China executive tells the world that China has become the factory for factories — a place where industrial giants come to learn, not just to sell — it signals that the center of gravity for programmable logic controllers, robotics, and smart manufacturing has decisively shifted eastward. For PLC vendors, system integrators, and procurement professionals, understanding this dynamic is no longer optional; it is the difference between leading the market and being left behind.
Analyst Insight: The declaration by Joe Ngai at WEF Dalian on June 24, 2026, is not hyperbole. China now accounts for over 50% of global industrial robot installations and is home to the world's largest installed base of automation equipment. The downstream effect on PLC consumption — the brains of every automated production line — is profound and accelerating.
What McKinsey's Joe Ngai Actually Said — and Why It Reshapes the PLC Landscape
Speaking to CNBC on the sidelines of the World Economic Forum in Dalian, Joe Ngai — McKinsey's China chairman — described a fundamental transformation in how the world views Chinese manufacturing. "China has evolved into the factory for factories," Ngai stated, emphasizing that global companies now travel to China to study automation deployment strategies rather than merely to sell equipment.
Ngai highlighted emerging automation hotspots across the country — clusters of manufacturing innovation where robotics density, PLC deployment, and industrial networking sophistication are reaching levels unseen anywhere else. This is not about low-cost labor; this is about technological supremacy in the production process itself.
Market Trend: The global industrial automation and control systems market reached $226.8 billion in 2025 and is projected to hit $250.3 billion in 2026, expanding at a CAGR of 10.5% toward $504.4 billion by 2033. China's domestic industrial automation market alone has surpassed 250 billion yuan, with PLCs representing one of the fastest-growing sub-segments.
The PLC Supply Chain: Winners and Strategic Shifts
Ngai's commentary delivers crucial market intelligence for the major PLC manufacturers with significant China exposure. Siemens, Rockwell Automation, Mitsubishi Electric, and Omron collectively command a substantial share of the Chinese PLC market — but the competitive dynamics are shifting rapidly as domestic Chinese automation firms continue to gain ground.
In 2024, domestic Chinese manufacturers supplied 52% of all industrial robots sold in China, up from under 30% a decade earlier. This rise of domestic automation champions — many of whom are now exporting globally — creates both competitive pressure and partnership opportunities for established PLC vendors.
China's Automation Leadership: Key Statistics (Click to Expand)
- Over 50% of global industrial robot installations are deployed in China.
- China is home to 40% of the world's cumulative installed base of industrial robots, surpassing 4 million units globally per IFR 2025 data.
- Chinese domestic robot manufacturers captured 52% market share in 2024, up from below 30% in 2014.
- Chinese robot exports grew 28% year-over-year in 2025.
- China's manufacturing value-added grew 6.1% YoY in 2025, maintaining its position as the world's largest manufacturer for the 16th consecutive year.
- The global industrial automation market is projected to grow from $250.3 billion (2026) to $504.4 billion (2033).
Why PLC Demand Is Structurally Accelerating
The "factory for factories" phenomenon has deep implications for PLC consumption. As China's manufacturing sector invests aggressively in greenfield smart factories — and retrofits legacy facilities with modern automation — the demand for mid-range and high-end PLCs, motion controllers, and industrial networking equipment continues to outstrip broader GDP growth.
Three structural drivers underpin this demand: first, the push toward carbon neutrality is forcing energy-intensive industries to adopt precision automation; second, a deepening shortage of skilled technical talent is accelerating the replacement of manual processes with PLC-driven systems; and third, the rise of industrial AI and edge computing is creating demand for next-generation controllers capable of real-time data processing.
Analyst Insight: The PLC market in China is bifurcating. On one end, nano and micro PLCs face commoditization pressure from low-cost domestic suppliers. On the other, high-performance modular PLCs with integrated AI acceleration and OPC UA connectivity command premium pricing and loyalty. The vendors winning in China are those investing in the high end while building ecosystem stickiness through software, services, and IIoT integration.
What This Means for Industrial Buyers and System Integrators
For procurement professionals and system integrators sourcing PLCs and automation equipment, the "factory for factories" dynamic presents both opportunity and complexity. China's automation supply base now offers credible alternatives to traditional European and Japanese PLC brands — often at 20–40% lower price points — while the incumbents are responding with aggressive localization and faster product cycles.
The strategic imperative is clear: treat China not as a sourcing afterthought but as a primary innovation node where automation best practices are being written in real time. Companies that fail to engage with China's automation ecosystem risk falling behind on both cost competitiveness and technological sophistication.
FAQ: China's PLC and Automation Market — What Buyers Need to Know
Q: Which PLC brands dominate the Chinese market?
Siemens remains the market leader in mid-to-high-end PLCs, followed by Mitsubishi Electric, Omron, and Rockwell Automation. Domestic brands such as Inovance and Hollysys are gaining share rapidly in the micro and nano PLC segments.
Q: Are Chinese-made PLCs reliable enough for critical applications?
Chinese PLCs have matured significantly. Top-tier domestic brands now offer products with MTBF ratings and certifications comparable to global incumbents, and they are increasingly deployed in automotive, electronics, and logistics automation.
Q: How does China's automation leadership affect global PLC pricing?
Increased competition from Chinese PLC manufacturers is exerting downward pressure on global pricing, particularly in the micro and mid-range segments. This benefits end-users but compresses margins for legacy vendors.
Q: What industrial sectors are driving the most PLC demand in China?
Electric vehicle (EV) battery manufacturing, semiconductor fabrication, logistics and warehousing automation, and renewable energy equipment production are the hottest demand verticals.
The Road Ahead: From 'Factory for Factories' to Automation Exporter
Ngai's assessment at WEF Dalian captures a pivotal moment. China is no longer merely the world's manufacturing floor — it is the architect of its automation blueprint. With 28% year-over-year growth in robot exports and domestic PLC manufacturers increasingly targeting international markets, the country is transitioning from being the largest consumer of automation equipment to becoming a major exporter of automation technology and know-how.
For the global PLC industry, the message is unequivocal: the competitive landscape will be shaped in China, and the window to establish or defend a position in this market is narrowing. The "factory for factories" is open for business — and it is rewriting the rules of industrial automation in real time.
