Research on the Path of Green Transformation of Resource-based City in Luzhou City by New Quality Productivity

The green transformation of resource-based cities serves as the core mission in implementing the concept of green, low-carbon, and high-quality development, while also acting as a key lever for new-type productive forces to empower regional coordinated development.Taking Luzhou City in the upper Yangtze River region as a case study, this research utilizes authoritative data from 2007 to 2025 and employs four analytical models: entropy-weighted TOPSIS-greasy correlation, coupling coordination degree, obstacle degree, and gray GM(1,1) models.The study systematically investigates the evolution characteristics of green transformation performance, the coupling coordination patterns of the four-dimensional system, core obstacle factors, and transformation pathways.Results demonstrate: ①Luzhou's green transformation performance has achieved a transition from imbalance to coordination, exhibiting three distinct phases: "improved imbalance →transitional fluctuations →enhanced coordination."Significant differences exist in the driving forces of the economic, social, resource, and ecological systems, with the social system demonstrating stable support while the resource system lags behind; ②The coupling coordination degree of the four-dimensional system steadily improves, evolving from mild imbalance to moderate coordination.The lag type shifts from ecological to resource-related, with no significant lag expected in 2025; ③Green transformation obstacles show dynamic evolution, transitioning from single-sector shortcomings to multi-factor constraints, with core obstacles concentrated in delayed industrial restructuring and low resource utilization efficiency; ④Based on these findings, a four-pillar transformation pathway-"industrial upgrading → technological innovation → ecological coordination → policy support" -is constructed.This provides theoretical references and practical examples for upstream Yangtze River cities and similar resource-based cities to achieve coordinated development of "industrial upgrading → ecological protection → livelihood improvement" through new-type productive forces.
