长江经济带绿色生产方式的测度及综合评价

推动生产方式绿色化是实现经济高质量发展和建设社会主义现代化国家的关键途径。基于绿色生产方式的内涵和外延,构建了涵盖绿色产业布局、绿色生产过程和绿色制造体系三个维度26个指标的长江经济带绿色生产方式指标体系,运用定基极差熵权法测度2015—2020年长江经济带生产方式绿色化水平作为其绿色生产方式的量化指标,并采用核密度估计、空间可视化分析及耦合协调度分析,对其时空演化特征和协同效应进行全面分析。研究发现：2015—2020年,长江经济带11省（市）的生产方式绿色化水平实现了较快提升,整体上呈现逐年上升态势,但沿线省（市）间生产方式绿色化水平的差异逐渐扩大;长江经济带生产方式绿色化水平呈现空间正相关性,但这种空间相关性在2017—2020年逐渐减弱。长江经济带生产方式绿色化水平存在明显的区域差异,呈现出“下游地区>中游地区>上游地区”的分布格局。长江经济带绿色生产方式中绿色产业布局、绿色生产过程和绿色制造体系三个维度的协同效应逐渐增强,但是整体协同水平依旧较低、地区差异明显,协同能力仍需提升。

The measurement and comprehensive evaluation of green production methods in the Yangtze River Economic Belt

Promoting the greening of production methods is a key way to achieve high-quality economic development and build a modern socialist country. Based on the connotation and extension of green production methods, a green production method indicator system for the Yangtze River Economic Belt covering three dimensions of green industrial layout, green production process and green manufacturing system and 26 indicators is constructed. The Fixed base range entropy weight method is applied to measure the green level of production methods as a quantitative indicator of its green production mode in the Yangtze River Economic Belt from 2015 to 2020, and kernel density estimation, spatial visualization analysis and coupling coordination degree analysis are used to conduct a comprehensive analysis of its spatial and temporal evolution characteristics and synergy effects. The study found that the greening level of production methods in 11 provinces (municipalities) in the Yangtze River Economic Belt achieved a relatively rapid increase between 2015 and 2020, showing an overall increase year by year, but the differences in the greening level of production methods among the provinces (municipalities) along the belt have gradually expanded. The level of greening of production methods in the Yangtze River Economic Belt shows a positive spatial correlation, but this spatial correlation gradually decreases between 2017 and 2020. There are obvious regional differences in the level of greening of production methods in the Yangtze River Economic Belt, showing a distribution pattern of "downstream areas > midstream areas > upstream areas". The synergy effect of the three dimensions of green industry layout, green production process and green manufacturing system in the green production mode of the Yangtze River Economic Belt is gradually increasing, but the overall synergy level is still low, with obvious regional differences, and the synergy capacity still needs to be improved.
