摘要
新型基础设施建设与城市绿色发展之间联系密切。文章在构建评价指标体系与分析二者耦合机理基础上,采用熵权法、非期望产出的全局Super-SBM模型、耦合协调模型测算2005-2019年中国大陆280个地级以上城市新型基础设施建设与绿色发展的协调度,并进一步分析其时空演变特征与影响因素。结果表明:①新型基础设施建设水平呈上升的时序变化,在空间格局上呈“南北低、西低东高”特征。城市绿色发展水平表现为“下降再上升”的时序变化趋势,并呈“东西南北高、中部塌陷"空间结构。②新型基础设施建设与城市绿色发展协调度不断攀升,由多极化转向单极化发展态势,并呈东北方向“陷落”的空间格局。③新型基础设施建设与城市绿色发展协调度具有显著的空间正相关性,而随着时间推移,协调度局部集聚特征减弱,趋向均衡发展。④经济发展、产业结构、环境规制、科学技术、对外开放度与城镇化水平是影响二者协调发展的重要因素,且作用强度存在区域异质性。
There is a close relationship between new infrastructure construction and urban green development.On the basis of constructing an evaluation index system for the two and analyzing their coupling mechanism,the research adopts the entropy weight method,the global Super-SBM model of undesired output and the coupling coordination model to measure the coordination degree between the new infrastructure construction and urban green development in 280 cities above the prefecture level from 2005 to 2019,and analyzes the spatio-temporal evolution characteristics and influencing factors.The results show that:1)The level of new infrastructure construction shows an upward temporal change,and the spatial pattern is characterized by"low in the north and south,low in the west,high in the east".The level of urban green development shows a time-series trend of"falling and then rising",and has a spatial structure of"high in the east,west,north and south,and low in the middle".2)The coordination degree between the new infrastructure construction and the urban green development continues to rise,from the multi-polarization development to the unipolar development,with a spatial pattern of"falling down"in the northeast direction.3)There is a significant positive spatial correlation between new infrastructure construction and urban green development.As time goes by,the local agglomeration of coordination degree weakens and tends to develop in a balanced manner.4)Economic development,industrial structure,environmental regulation,science and technology,opening degree and urbanization level are important factors that affect the coordinated development of the two,and there is regional heterogeneity in the intensity of their effects.
