绿色物流—数字经济—高质量发展系统耦合协调及时空演化研究OACHSSCDCSTPCD

Digital economy and green logistics are important measures and concrete manifestations for high quality development re-spectively,and it is the key that we can coordinate the three-dimensional system of green logistics,digital economy and high quality development effectively to achieve a higher level of sustainable development.The evaluation index system of coupling and coordinated development of three-dimensional system was constructed,and it conducted a comprehensive study on the temporal evolution and spa-tial differentiation characteristics of comprehensive development level and coupled coordination of three-dimensional system in 30 provinces with the entropy weight method and coupling coordination model.The results showed that the comprehensive development level and coupling coordination degree of the three-dimensional system were on an upward trend yearly with the coupling coordination level in the coupling development stage,while the two-dimensional system was in the grinding development stage,and their contribution nee-ded to be strengthened time-wise.Spatially,there was spatial heterogeneity in the comprehensive level,coupling coordination degree and their constraining factors of the three-dimensional system,presenting a distribution pattern of"high in the east and central,low in the west"and showing an olive-shaped distribution characteristic of"more middle-level regions,fewer high and low-level re-gions".On the above,it proposes to develop the three-dimensional system in a coordinated manner through making up for the short-comings of development,promoting the coordinated development of the two-dimensional system and optimizing the spatial layout.
