中国省域生态文明建设与绿色生产耦合协调发展的时空格局及影响因素

Spatial and Temporal Patterns and Influencing Factors of the Coupling Coordinated Development of Ecological Civilization Construction and Green Production in China’s Provincial Areas

生态文明建设(ECC)和绿色生产(GP)是实现人与自然和谐共生的重要实践。因此,探求生态文明建设与绿色生产之间的耦合机制,并建立耦合状态评估体系,以深入探讨两者的关系对实现人与自然和谐共生至关重要。本文针对中国31个省份,分别建立了生态文明建设和绿色生产的评价体系。随后,采用熵权法和耦合理论构建了耦合协调度(CCD)模型,并运用随机森林方法研究了CCD的内部影响因素。研究结果表明,2012—2020年,中国各省份的生态文明建设与绿色生产的耦合协调度逐渐上升,空间差异逐渐减小。科技投入与产值、水污染排放效应和收入消费水平等因素是影响系统耦合协调度的主要驱动力,对于实现理想的耦合协调水平具有重要贡献。

Ecological civilization construction(ECC)and green production(GP)are important practices to achieve harmonious coexistence between humans and nature.Therefore,exploring the coupling mechanism between ecological civilization construction and green production,and establishing a coupling assessment system to deeply explore the relationship between the two is crucial to achieving harmonious coexistence between human beings and nature.In this paper,the evaluation systems of ecological civilization construction and green production are established for 31 provinces in China.Subsequently,the coupling coordination degree(CCD)model was constructed using the entropy weight method and coupling theory,and the internal influencing factors of CCD were investigated using the random forest method.The results of the study show that from 2012 to 2020,the coupling coordination degree of ecological civilization construction and green production gradually increased and the spatial differences gradually decreased in all provinces of China.Factors such as scientific and technological input and output value,water pollution emission effect and income and consumption level are the main driving forces influencing the coupled coordination degree of the system,and they have an important contribution to the achievement of the desired coupling coordination level.
