Spatiotemporal evolution of the coupling coordination between new infrastructure investment and new urbanization development
Based on the coupling mechanism between new infrastructure investment and new urbanization development,an indicator system is constructed and the evaluation indicators are weighted by using the entropy weight method.The coupling coordination degree evalua-tion model,spatial autocorrelation model and standard deviation ellipse model are used to in-vestigate the coupling and coordination between new infrastructure investment and new ur-banization development in 30 provinces(autonomous regions and municipalities)from 2013 to 2020.The results show that:the composite indexes of new infrastructure investment and new urbanization development increased from 0.104 and 0.234 in 2013 to 0.177 and 0.363 respectively;the degree of the coupling coordination between new infrastructure investment and new urbanization development continues to rise,but there are obvious differences be-tween regions,showing a decreasing pattern from east to west;during the study period,the fluctuation of Moran's I index increased,and the coupling coordination degree had a signifi-cant positive spatial correlation;the standard deviation elliptic center of gravity migrates slightly towards the southwest and the area of ellipse decreases continuously.The coupling coordination degree shows a trend of agglomeration and convergence.Therefore,we should continue to strengthen the macro-control and the regional driving role of the eastern coastal are-as,so as to further realize the coordinated development of new infrastructure and new urbanization.
