1. Introduction: A Three-Stage Model of FDI System Evolution + Definition of Key Variables
From the perspective of the systemic evolution of global foreign direct investment (FDI), its essence is not a linear "capital migration," but a dynamic system co-driven by costs, institutions, supply chain networks, and geopolitical risks. Based on the transnational capital flow framework of UNCTAD and the World Bank, FDI evolution can be divided into three major stages:
- 2010–2016: Cost-driven stage (Global manufacturing efficiency maximization)
- 2016–2020: Early supply chain dispersion (Risk diversification and regionalization initiation)
- 2020–present: Resilience restructuring stage (Security, resilience, and multi-node system)
The system's main variable is no longer a single "cost optimization," but a four-dimensional coupling structure:
Cost × Risk × Ecosystem Lock-in × Institutional Stability
The essence of FDI flows is the dynamic reweighting among the four variables, not simple migration.
2. Empirical Structure Layer
2.1 UNCTAD Logic Mapping: FDI Structural Change Mechanisms
According to UNCTAD's long-term data logic, global FDI exhibits three structural changes:
- Decline in the share of manufacturing FDI → Rise of service and digital capital
- Decline in concentration in a single country → Rise of regional clustering
- Increased volatility in resource-based investment → Enhanced strategic resource lock-in
This means FDI has shifted from an "efficiency-driven system" to a "resilience-driven system."
2.2 Three-Stage Temporal Structural Evolution
2010–2016: Global Cost Minimization Phase
- China and Eastern Europe as core manufacturing hubs
- Corporate logic: economies of scale + labor arbitrage
2016–2020: Early Supply Chain Dispersion
- US-China trade friction + tariff structure changes
- Companies begin "China+1" layout
2020–present: Resilience Restructuring Phase
- Pandemic + geopolitical conflicts + energy transition
- Supply chains shift from "efficiency networks" to "redundancy networks"
2.3 Regional Industrial Structure Fact Mapping
- Southeast Asia: Electronics assembly, auto parts, midstream new energy
- South Asia: Labor-intensive manufacturing (textiles, light industry)
- Latin America: Resources + nearshoring
3. System Driver Layer (Drivers + Trade-off Mechanism)
The core of the FDI system is not a list of variables, but the "substitution relationships between variables."### 3.1 Trade-off Compensation Model
There is a clear substitution logic in FDI decision-making:
- Weak cost advantage → Compensated by institutional stability
- Weak infrastructure → Compensated by geographic clustering
- Weak market size → Compensated by export orientation
- High political risk → Compensated by supply chain diversification
Therefore:
FDI is not about finding the "optimal country", but about finding a "compensable structural combination"
3.2 Conflict Structure
There are three types of structural conflicts within the system:
- Efficiency vs Security (Cost vs Risk)
- Concentration vs Dispersion (Economies of Scale vs Resilience)
- Localization vs Globalization (Market Embeddedness vs Network Spillovers)
4. FDI Transmission Mechanism Layer
4.1 Micro Behavioral Layer
FDI flows are driven by firm-level "portfolio optimization behavior", not unilaterally determined by macro policies.
- Apple: Supply chain disaggregation
- Logic: Risk diversification + modular production
- Result: Design concentrated + manufacturing distributed globally
- Intel: Choosing Malaysia
- Logic: Backend packaging ecosystem + mature industrial clusters
- Essence: Not cost-driven, but "process ecosystem lock-in"
- Tesla: Reliance on Indonesia's nickel resources
- Logic: Resource lock-in + vertical integration of the battery supply chain
- Essence: Upstream resource control substituting downstream manufacturing costs
4.2 Capital Flow Path
FDI pathways are no longer single-point relocation, but rather:
A four-stage decomposition network: "Design—Manufacturing—Assembly—Resources"
Capital performs functional slicing across different countries, rather than moving as a whole.
5. Dynamic Node System
Vietnam
- Functional role: Electronics manufacturing relocation hub (China+1 core node)
- Internal conflict: Infrastructure and technology upgrade lag
- External pressure: Manufacturing substitution competition from India and Indonesia
- Evolution path: From low-end assembly → mid-end manufacturing upgrade
Indonesia
- Functional role: Resource + new energy upstream core (nickel industry chain center)
- Internal conflict: Imbalance between resource dependence and industrial upgrading
- External pressure: Competition from Latin American resource countries
- Evolution path: Resource export → battery materials integration center
Malaysia- Functional Role: High-end electronics packaging and semiconductor back-end hub
- Internal Conflict: Talent structure bottleneck and pressure from industrial upgrading
- External Pressure: Substitution risk from Vietnam's manufacturing upgrade
- Evolution Path: Back-end processing → Semiconductor ecosystem node
6. Global Substitution Network + Regional System Competition
The core of FDI restructuring is not "relocation" but "functional slice substitution."
- Southeast Asia: Manufacturing slice substitution (Vietnam/Thailand/Malaysia)
- South Asia: Labor-intensive substitution (Bangladesh/India)
- Latin America: Near-shore substitution (Mexico/Brazil)
Essential Change:
Global supply chains shift from "country competition" to "functional module competition"
7. System Feedback Loops + Stability Analysis (Key Modules)
7.1 Loop A: Cost Erosion Loop (Divergent)
FDI inflow → Wage rise → Cost advantage decline → Enterprise relocation → New region activation
This loop explains:
- Partial industrial spillover from China's coastal areas
- Vietnam taking over electronics manufacturing
- India taking over service outsourcing
👉 This loop has continuous diffusivity (non-equilibrium expansion)
7.2 Loop B: Resilience Enhancement Loop (Convergent)
Supply chain dispersion → Management complexity → Re-concentration of key nodes → Formation of stable core hubs
Result:
- Semiconductor packaging concentrated in Malaysia
- High-end chip design concentrated in the US
- Battery resources concentrated in Indonesia
👉 This loop forms a "dispersion-re-concentration" dynamic equilibrium structure
7.3 System Stability Judgment
Stable Systems:
- Southeast Asian manufacturing cluster (medium-term stable)
- Semiconductor back-end ecosystem (highly stable)
Unstable Systems:
- Single low-cost dependency model (highly fragile)
- Resource-export FDI structure (price cycle sensitive)
8. Conclusion: FDI Dynamic System Model (Interpretable + Real-World Mapping)
8.1 Enterprise Behavior Model
Enterprise FDI decisions are no longer cost-optimal, but:
A dynamic weighted function of cost + risk + ecosystem dependency
8.2 Country Role Evolution
- Vietnam: Manufacturing substitution node → Mid-end upgrade node
- Indonesia: Resource center → New energy core node
- Malaysia: Back-end packaging → Semiconductor hub node
Country roles are no longer static, but "functional modular evolution."
8.3 Global Structural Trend
- Global FDI is shifting from a "center-periphery structure" to a "multi-hub network structure"
- Supply chains are no longer linear, but "multi-path redundant systems"
