Synergistic Development of New Quality Productive Forces and Logistics Industry: A Case Study of Panzhihua City

New Quality Productive Forces (NQPF), driven by high technology and efficiency, are pivotal for high-quality development.As a foundational industry, the logistics sector plays a critical role in regional economies.Investigating the synergy between NQPF and logistics is essential for fostering their mutual advancement.This study examines Panzhihua City from 2018 to 2022, constructing an evaluation system to assess their synergistic development using entropy weighting and coupling coordination models.Results show that NQPF's comprehensive development index rose from 0.445 to 0.579, while logistics surged from 0.208 to 0.838.The systems maintained high-level coupling (C > 0.9), with coordination improving from barely coordinated (0.552) to well-coordinated (0.838), reflecting a robust interactive pattern.This research provides empirical evidence and policy insights for regional synergy.
