Decoupling or Deepening? A Quantitative Analysis of China's Value Chain Embeddedness in Global Production Networks

Decoupling or Deepening? Quantitative Analysis of China's Value Chain Embeddedness Based on Global Production Networks

Event Overview

Since 2015, "decoupling" has gradually evolved from a theoretical concept into a practical tool of U.S. policy toward China. From tariff increases on specific goods, to industrial policies centered on "reshoring manufacturing," to the recent inclusion of "third-country specific market situations" (third-country PMS) in trade remedy measures, Washington's targeting scope has continued to expand, directly targeting trade links circumvented via third-party "transshipment." These measures affect not only U.S.-China bilateral trade but also key "transit" nodes in the global supply chain network.

However, a study recently published in *Humanities and Social Sciences Communications*, based on a quantitative analysis framework of global production networks (GPN), presents an empirical picture different from the "decoupling thesis." Using multi-regional input-output (MRIO) data to construct a global industrial value chain network model, the study systematically assesses the degree of decoupling at the economy and industry levels. The results show that despite sustained external pressure, China's connections in global value chains (GVCs) were actually strengthened during the pandemic, with adaptability exceeding expectations.

Supply Chain Background

Understanding this assessment requires returning to the underlying structure of global value chains. The division of labor in modern manufacturing is highly fragmented; the production of a final product often spans multiple economies, and cross-border flows of intermediate goods constitute the bulk of global trade. Traditional trade value statistics tend to distort the true degree of bilateral dependence, while a value-added perspective can reveal who truly profits from production and who bears risks.

The multi-regional input-output model (MRIO) provides a methodological foundation here. It views the global economy as a network composed of industry nodes, depicting the extension paths of production chains through inter-industry intermediate goods transaction matrices. On this basis, researchers can quantify whether a country or industry is upstream or downstream in the global production network, and how close its connections are.

Current global supply chains are in a period of deep restructuring. Regionalization, nearshoring, and digitalization are intertwined, with companies pursuing both efficiency and security. As the global manufacturing hub, China's role is evolving from "world factory" to "market + innovation engine." This transformation necessarily brings shifts in value chain positions, but it does not mean China is excluded from global circulation.

Business Decision Logic

For chief procurement officers (CPOs), supply chain layout is never a simple either-or decision. A key insight noted in the paper is that industries deeply involved in intermediate goods trade, such as electronics and mechanical equipment, demonstrated greater stability when hit by systemic shocks. The reason is that the supplier systems in these industries are highly proprietary; technical specifications, customization levels, and certification cycles constitute high switching costs. Even if tariffs rise, customers may share costs to maintain supply continuity.By contrast, resource-based industries (such as primary processed goods and bulk raw materials) are more likely to be harmed in trade frictions. Because products are highly standardized, buyers can relatively easily find alternative sources of supply from other countries. This divergence explains why different industries have vastly different perceptions of "decoupling."

The "China+1" strategy widely adopted by enterprises is not about simply withdrawing from China, but rather about establishing flexible backups in Vietnam, India, Mexico, and elsewhere while retaining deep production capacity in China. In essence, this strategy is risk hedging rather than a long-term shift. The research also finds that China's "dual circulation" strategy has strengthened the self-supporting capability of its domestic industrial chain and improved its resilience under external shocks. Multilateral trade agreements (such as RCEP) and "backdoor" transshipment routes have become viable options for enterprises to circumvent U.S. restrictions in the short term.

Supply Chain Impact

From a supplier management perspective, Chinese suppliers' position in high-end intermediate goods remains solid. They possess mature process experience, rapid-response engineering capabilities, and large-scale R&D investment—factors that are difficult to replace in the short term. From a manufacturer's perspective, capacity layout has taken on a "China+N" composite structure, in which China's capacity utilization remains at a relatively high level, and newly added nodes serve more of an "insurance" function.

Procurement costs and delivery lead times have undergone complex changes. Tariffs add to direct costs, but the production line reconfiguration, worker training, and logistics re-planning brought about by supply chain shifts generate even higher hidden transition costs. Corporate inventory strategies have shifted from the pursuit of extreme "just-in-time" (JIT) to holding safety stock, leading to lower global inventory turnover and more capital tied up, yet this cost is regarded as a necessary investment in supply chain resilience.

In terms of transportation efficiency, altered trade routes have spawned a new set of transshipment hubs, such as Southeast Asian ports and Mexico's border industrial zones. Logistics integrators are adjusting their network designs to cope with more frequent compliance filings and multi-leg transportation demands. Digital supply chain development has become a key tool for reducing information friction, and real-time visibility helps enterprises manage their risk exposure more precisely.

The research also shows that the resilience of a supply network comes not from "self-sufficiency," but from the substitutability of connections. Highly integrated developed economies (such as Germany and Japan) demonstrate stronger shock resistance by plugging into multiple production networks simultaneously. This reminds us that true resilience is the product of "redundant connections," and that relying solely on a single market amplifies vulnerability.

Regional Impact

Within the Asian region, the industrial chain collaboration between China and ASEAN has been further deepened by RCEP, with the scale of intermediate goods trade continuing to expand and gradually forming a new pattern of "intra-regional circulation + exports to the global market." Japan and South Korea, leveraging their technological and capital advantages, maintain key positions in the high-end materials and equipment segments.On the one hand, Europe is advancing "strategic autonomy"; on the other, it is forming closer manufacturing collaboration networks with Central and Eastern European countries. Nearshoring within the EU manifests as relocating some production capacity from Asia back to countries such as Poland and the Czech Republic, in order to shorten delivery cycles and mitigate logistics risks.

In North America, the United States has used industrial policies such as the Inflation Reduction Act to shift new-energy supply chains toward Mexico and its own domestic market. Mexico, as a major beneficiary of "nearshore manufacturing," has seen notable export growth to the U.S., yet it still relies heavily on China for high-end components. This shows that "friend-shoring" cannot completely sever existing production networks in the short term.

The Middle East and Latin America play the roles of "transit corridors" and "resource suppliers" in global supply chains. The UAE and Saudi Arabia leverage their geographic positions to develop re-export trade, while Brazil, Chile, and others benefit from demand for minerals and agricultural products. Africa's participation is relatively limited, but as a source of critical minerals (such as cobalt and lithium), its strategic value is being reassessed.

Future Trends

Over the next 1 to 5 years, China's relationship with global value chains will present a picture of "layered restructuring." In geopolitically sensitive areas (such as advanced semiconductor manufacturing processes and key industrial software), supply chains will become further regionalized, and may even see technology restrictions and "exclusive systems." However, in emerging sectors such as new energy, electric vehicles, and industrial robotics, China will remain the world's most important market and manufacturing node, deeply participating in and even leading global production networks.

Digitalization and ESG (Environmental, Social, and Governance) requirements will reshape supplier management systems. Companies will place greater emphasis on supply chain transparency and sustainability, and Chinese companies' investments in green supply chains and digital factories are expected to translate into new competitive advantages. Global sourcing strategies will also shift from "cost priority" to "resilience priority," but China's combined advantages in cost, speed, and scale will still make it the preferred or core link in many industry chains.

Taken together, the researchers conclude that China has not decoupled from global value chains but is instead proactively adjusting how it embeds itself—moving from "scale-driven" to "innovation-driven" and from a "single hub" to "multi-node coordination." The future of global supply chains is not rupture, but restructuring and upgrading.

Key Conclusions

• China's connections in global value chains were strengthened, not weakened, during the pandemic.
• Industries with intensive intermediate goods trade are more resilient to shocks than resource-based industries, and supplier relationships exhibit stickiness.
• The domestic circulation strategy has enhanced China's resilience to external trade challenges while maintaining deep participation in global networks.
• Multilateral trade agreements and transshipment through third countries are effective tools for short-term buffering of U.S. restrictions.
• Supply chain resilience depends on a balance between network depth and substitutability, rather than simple self-sufficiency.
• Digitalization and ESG requirements are reshaping global sourcing strategies, and China is expected to continue playing a core role in the new round of restructuring.
