Replication Package for "Relational Selectivity and Structural Inference in Global Trade Networks"

This replication package contains the data-processing materials, derived network data, analysis scripts, canonical outputs, and verification records supporting the study “Relational Selectivity and Structural Inference in Global Trade Networks.”The study analyzes the 2024 global merchandise-trade network using CEPII BACI HS17 release V202601. The package includes the derived 226 × 226 bilateral trade matrix expressed in billions of current USD, the country-code mapping used in the analysis, Python scripts for network construction and analysis, canonical output files, SHA-256 checksums, and a verification record.The analyses cover absolute trade-value threshold networks, exporter-relative relational fields, system-level connectivity and centralization, Louvain community robustness, positional correspondence across degree, strength, and betweenness, and exporter–importer size-only benchmarks.The computational environment used for the verified analysis was Python 3.11.16, NetworkX 3.6.1, pandas 3.0.5, and NumPy 2.4.6.The original CEPII BACI product-level source file is not redistributed in this archive. Users should obtain BACI HS17 2024 release V202601 directly from CEPII. The included processing materials permit reconstruction of the derived bilateral matrix from the source data.Version 1.1 is the verified replication package used for the associated manuscript.
