Spatio-temporal Differentiation and Influencing Factors of Urban-rural Integration Development in Chengdu-Chongqing Economic Circle
This paper explored the spatio-temporal differentiation characteristics and influencing factors of ur-ban-rural integration level at the county level in the Chengdu-Chongqing Economic Circle from 2007 to 2020 by u-sing improved entropy method,Jenks natural fracture method,and obstacle model.The results show that:(1)The level of urban-rural integration development in the Chengdu-Chongqing region continues to improve,with the urban-rural integration index increasing from 0.239 in 2007 to 0.534 in 2020,the number of low and lower level integra-tion areas decreasing from 25 in 2007 to 8 in 2020,and the number of high and higher level integration areas in-creasing from 2 to 12.(2)The development of different integration dimensions is not synchronized,and the highest index of social integration development level is 0.612 in 2020.(3)The high-level integration zone forms two small-scale agglomeration areas in the western and southeastern parts of the Chengdu-Chongqing region,presenting a development pattern of"dual core dominance"but"central collapse".(4)The obstacles degree to urban-rural integration development in the Chengdu-Chongqing Economic Circle are relatively higher in the early stage due to natural factors than population,land,and financial factors.In the later stage,the obstacles degree of natural fac-tors decrease,while the obstacles degree of industrial structure and financial factors are more significant.
