The Ecological Industrial Park Driving Industrial Chain Resilience: The Logic of Green Industry Layout in Global Supply Chain Restructuring

Driving the Resilience of the Industrial Chain with Eco-Industrial Parks: The Logic of Green Industry Layout in Global Supply Chain Restructuring

Introduction: Reshaping the Industrial Foundation Amidst Global Uncertainty

Against the backdrop of deep global economic integration and increasing uncertainty, regional economies are facing unprecedented systemic risks. For economies centered on manufacturing, the resilience of the industrial chain is no longer just a matter of production efficiency; it is the core lifeline for resisting external shocks and internal structural crises. The immense achievements of China's manufacturing sector also expose deep structural contradictions in its innovation capabilities, added value enhancement, energy dependency, and environmental carrying capacity. This risk of "low-end lock-in" and the urgent need for "green transformation" jointly constitute a dual pressure on China's industrial development.

Traditional economic development models are unable to cope with this dual squeeze. In this macro context, Eco-Industrial Parks (EIPs), as an innovative model integrating green production, low pollution, and a circular economy, are moving from regional pilot projects to systemic strategies, becoming a key institutional tool for reshaping industrial chain resilience. The construction of EIPs is no longer just about simple land and industrial agglomeration; it represents a paradigm shift from linear production to ecological synergy.

Mechanisms for Enhancing EIP Resilience: Coupling from Institutional to Ecological

Academic research on the impact of EIPs on industrial chain resilience has shifted from single environmental benefit assessments to in-depth analysis of the underlying mechanisms. Research indicates that the contribution of EIPs to industrial chain resilience is not a single external input but is driven by a series of mutually coupled internal mechanisms.

**1. Entry Threshold & Regulatory System:** EIPs effectively attract capital and high-tech enterprises by providing a series of preferential policies and subsidies. This institutional "gravitational field" lowers the initial risk for new entrants, thereby accelerating technological innovation and industrial upgrading. Strict environmental assessment standards within the park compel enterprises to embed environmental management into production and operation, creating institutional green constraints.

**2. Circular Economy & Industrial Ecology:** The core competitiveness of EIPs lies in their internal system construction based on the principles of industrial ecology. It encourages a network of synergy between enterprises regarding material and energy flows, achieving efficient internal transfer and reuse of resources and waste. This internal "ecosystem" operation greatly improves the efficiency of resource and energy utilization, reduces dependence on the external environment, and thus enhances the inherent redundancy and shock resistance of the supply chain.**3. Green Technology Innovation:** The concentration effect of EIPs accelerates the R&D and application process of green technologies. Environmental constraints become catalysts for innovation, forcing enterprises to invest in low-carbon, high-value-added green technologies, which directly drives the structural upgrading of China's manufacturing sector—a transition from traditional high-pollution manufacturing to green, low-carbon industries. This is the fundamental path to enhancing the overall added value of the industrial chain.

Regional Heterogeneity: Spatial Differentiation of Resilience Contribution

The impact of EIPs on industrial chain resilience is not spatially uniform; its effects manifest with significant heterogeneity across different regions. Research has found that in pilot cities, the establishment of EIPs can bring an industrial chain resilience improvement of 1.56% to 2.75%. However, the amplification mechanisms of this marginal effect differ significantly across regions:

* **Regional Differences:** Compared to eastern coastal areas, the role of ecological industrial parks in enhancing industrial chain resilience is more prominent in **central and western regions**. This may be highly correlated with the urgency of industrial structure adjustment, the collaborative investment in infrastructure, and the strategic needs for regional economic balance in these areas. * **Regional Integration Effects:** In regions with a higher degree of regional economic integration, the positive impact of EIPs is particularly significant. This indicates that the synergistic effects of EIPs can better activate industrial clusters within the region, forming stronger regional industrial chain synergies, thereby resisting external shocks at the macro level.

This regional differentiation suggests that when formulating industrial policies, we must go beyond single regional development indicators and incorporate the regional industrial foundation, environmental carrying capacity, and regional integration into the comprehensive consideration framework for EIP layout.

Policy Implications: Building a Systemic Resilience Framework

Faced with the accelerated restructuring of global supply chains and the structural challenges facing domestic industries, the strategic value of EIPs has transcended mere environmental governance, rising to the level of national industrial security and economic structural resilience. Policymakers should focus on the following key points:

1. **From Point to System:** Policy design should avoid "scattered" park construction and instead focus on building networks of ecological industrial parks with regional synergistic effects to maximize spatial spillover effects. 2. **Deepening Mechanisms:** Policy support should shift from simple subsidies to building deeper operational standard systems that match the circular economy and industrial ecology, ensuring that EIPs can continuously drive technological innovation rather than merely relying on policy dividends. 3. **Addressing Dual Challenges:** Policy direction must simultaneously resolve the contradictions between "low-end lock-in" and "green transformation" through mandatory innovation indicators and green financial instruments to ensure the endogenous driving force for industrial upgrading.

Conclusion: Long-Term Returns on Resilience Investment## Conclusion: Long-term Returns of Resilient Investment

The construction of ecological industrial parks is a key practice in the global economic transition towards a sustainable development model. It is not only a tool for environmental governance but also a strategic investment in an industrial ecosystem with inherent risk resistance, designed for future uncertainties. As global capital becomes increasingly stringent regarding ESG and green investment standards, regions that can transform environmental constraints into industrial competitive advantages will become core nodes in reshaping the global value chain. The strategic layout of EIPs is essentially a forward-looking investment in the long-term resilience of the economic structure.
