Spatio-temporal characteristics and analysis of influencing factors of inclusive green growth in China’s oil and gas resource industry
Published 2025-01-01“…Key observations include: (1) IGGOG exhibited a general upward trajectory, albeit with periodic fluctuations. (2) IGGOG’s spatial distribution adopts a “periphery-center” pattern, with pronounced spatial disparities. (3) Significant positive spatial autocorrelation in IGGOG is predominantly evident in high-high (HH) and low-low (LL) clusters. (4) Factors such as industrial agglomeration, industrial structures upgrading, urbanization rates, digital economy, and openness positively correlate with IGGOG, whereas green burdens adversely affect it. …”
