长江经济带林业绿色经济效率的时空演化及驱动因素的空间溢出效应
Spatio-temporal evolution and spatial spillover effects of driving factors of forestry green economic efficiency in the Yangtze River Economic Belt
摘要
Abstract
Enhancing forestry green economic efficiency is of great significance for balancing economic growth and ecological protection,thereby promoting the high-quality development of the Yangtze River Economic Belt.Based on the panel data from 11 provinces in the Yangtze River Economic Belt from 2004 to 2023,this study incorporated forestry carbon emissions and pesticide usage into an undesirable output framework.The Super-SBM model was employed to measure forestry green economic efficiency.Kernel density estimation and Moran's I index were used to characterize its spatiotemporal evolution,while the Spatial Durbin Model was applied to investigate the driving effects of technological innovation and environmental regulation,along with their spatial spillover mechanisms.The findings showed that:(1)During the study period,forestry green economic efficiency exhibited a fluctuating upward trend,with regional disparities gradually narrowing.Spatially,it presented a stepwise declining pattern of"downstream>midstream>upstream".The global Moran's I index was significantly positive,indicating a continuously strengthening spatial agglomeration.(2)Technological innovation and environmental regulation were identified as the core drivers of efficiency improvement,both exerting significant positive impacts on local efficiency.In contrast,the industrial structure,constrained by a lagging transition,showed a significant negative inhibitory effect.(3)Both technological innovation and environmental regulation demonstrated significant positive spatial spillover effects,the indirect effect of technological innovation was particularly prominent,far exceeding its direct effect,which confirmed the strong diffusion capacity of green technologies.Policy implications:strengthening the leading role of technological innovation and establishing a basin-wide green technology diffusion network,collaboratively promoting environmental regulation policies to amplify positive spatial spillovers,accelerating the upgrading of the forestry industrial structure to promote green transitions according to local conditions,strengthening institutional constraints and incentives,integrating forestry green efficiency into local government performance assessment,so as to provide institutional guarantee for the high-quality green development of forestry in the Yangtze River Economic Belt.关键词
