Value chain network under dual circulation: Supply chain attacks and defense - Softcover

Inhaltsangabe

Under the interactive background of global value chain (GVC) restructuring and the dual-circulation development strategy, this study systematically investigates the dynamic adjustment mechanisms of multinational enterprises' sales networks and their impact pathways on value chain upgrading. Building on the intersection of international trade theory and corporate strategic management, a multi-dimensional analytical framework incorporating spatial heterogeneity characteristics is constructed, breaking through the limitations of traditional static analyses on geographical boundaries and organizational forms.
The research first identifies the driving factors of post-2008 global financial crisis sales network restructuring through a Difference-in-Differences (DID) model, innovatively introducing modular decomposition algorithms to deconstruct the topological features of value chains1618. By integrating customs databases, corporate supply chain data, and WTO policy texts into a hybrid dataset, empirical analysis using Vector Autoregression (VAR) models and structural breakpoint testing methods reveals dual trends of "regional agglomeration" and "digital platformization" in sales network restructuring amid Sino-US trade frictions.
Key findings include:

1. 1.The dual-circulation pattern drives enterprises to form a "core-periphery" nested sales network structure through institutional embedding and technology diffusion pathways.
2. 2.Flexible supply chain management efficiency exhibits industry heterogeneity, with manufacturing response speeds surpassing service industries by 23.6% (p<0.01).
3. 3.Value chain upgrading demonstrates steepening "smile curve" characteristics, where digital technology adoption increases R&D-end added value by 19.8% while reducing manufacturing-end value by 7.2%.

Theoretical contributions manifest in three aspects:
① Proposing a dynamic sales network adaptation model to enhance analytical dimensions of global production network theory.
② Developing a multi-granularity hesitant fuzzy linguistic evaluation system to address applicability limitations of traditional decision-making models in uncertain environments.
③ Creating a GVC measurement toolkit based on complex network analysis, enabling multi-scale observations from micro-enterprise to macro-industrial levels.
Practically, this study establishes a "Dual-Circulation Resilience Index" evaluation system for enterprises and provides policymakers with a strategic decision-support framework containing 12 core indicators, including institutional compatibility and technology absorption rates.
