高质量发展与“两山”转化:测度及时空演进

High-Quality Development and“Two-Mountains”Conversion:Measurement and Space-Time Evolution

高质量发展和“两山”转化是一枚硬币的正反两面。基于“两山”转化构建高质量发展评价指标体系,引入耦合协调度评价“金山银山”与“绿水青山”两个维度间的相互转化水平,引入皮尔逊系数探讨高质量发展与“两山”转化的相关性,进而分析相关指数的空间分布及时空演进特征。研究发现:(1)2009—2019年,我国高质量发展水平呈现逐年上升趋势,各省高质量发展水平高低、驱动因素与薄弱环节存在显著差异;(2)“绿水青山”与“金山银山”呈现耦合度与耦合协调度逐年上升趋势,总体处于勉强耦合协调状态,即“两山”转化水平处于中等偏低层次;(3)高质量发展水平与耦合协调度正相关,即高质量发展水平越高,“两山”转化水平越高;(4)高质量发展水平与耦合协调度均表现出显著的空间相关性,高质量发展与“两山”转化均存在空间溢出效应。

High-quality development and the“two mountains”conversion are similar to the two sides of a coin.Based on the goal of such“conversion”,an evaluation index system for high-quality development is constructed.Under this system,the characteristics of spatial distribution and space-time evolution of relevant indexes are analyzed by introducing two crucial factors,which are the coupling coordination and the Pearson coefficient.The former aims to evaluate the“two mountains”conversion,and the latter is for exploring the correlation between high-quality development and the“Conversion”.The findings of the study are as follows:(1)During 2009-2019,high-quality development has been on an upwaed ternd,though varied dramatically across provinces in terms of their levels,driving factors and weak links.(2)“Clear waters and lush mountains”and“Golden Mountains and Silver Mountain”show an upward trend of coupling degree and coupling coordination degree year by year,and they are generally in a state of barely coupling and coordination,that is,the transformation level of“two mountains”is at a medium to low level;(3)The level of high-quality development is positively correlated with the degree of coupling coordination,that is,the higher the level of high-quality development,the higher the transformation level of the“two mountains”;(4)Both high-quality development and coupling coordination manifest a significant spatial correlation,and there is a certain spatial spillover effect between high-quality development and“two mountains”conversion.
