摘　　要：基于内部动力系统、外部动力系统构建城乡融合发展动力评价体系,运用BP神经网络模型对2020年我国成渝地区132个区县的城乡融合发展动力进行识别,根据识别结果提炼出城乡一体、以城带乡、以乡促城和收缩重构四种县域城乡融合类型,并针对不同融合类型提出差异化的城乡融合发展路径。研究结果表明,成渝地区西部的城乡融合发展水平较高,但对照全国情况来看没有明显优势。除成渝都市圈附近和成渝中轴城际交通走廊沿线的区县外,成渝地区大部分区县内部与外部动力均不足,城乡融合发展类型以收缩重构型为主。城乡一体型县域应按照“功能互补、生活等值”方式加强城镇与乡村的双向互促发展。以城带乡型县域应按照“以工代农、以城带乡”方式,利用城镇规模效应带动乡村外源发展。以乡促城型县域应按照“农业升级、以农促工”方式,通过农业链条延伸促进城镇涉农企业发展。收缩重构型县域应按照“择优发展、绿色发展”方式探索乡村有序重构和生态价值转化。研究结论可为成渝地区因地制宜推进县域城乡融合发展提供理论支持和实践借鉴。This paper develops an evaluation framework for urban-rural integration dynamics from two subsystems of both internal and external dynamics.Employing the BP neural network model,the research assesses urban-rural integration dynamics across 132 districts and counties in the Chengdu-Chongqing region.Based on the analysis,four distinct types of county urban-rural integration are identified:urban-rural oneness type,city-led rural type,rural-promoted city type,and contraction-reconstruction type,corresponding differentiated development paths are proposed for each type.The results reveal that,despite a higher level of urban-rural integration in the western Chengdu-Chongqing region,this advantage is not pronounced relative to the national context.Except for districts and counties adjacent to the Chengdu-Chongqing Metropolitan Area and along the Chengdu-Chongqing Central Axis intercity transportation corridor,the majority of districts and counties exhibit insufficient internal and external dynamics,with the contraction-reconstruction type being predominant.For urban-rural oneness counties,it is recommended to implement a strategy that emphasizes“functional complementarity and parity in living standards”to foster mutual development between urban and rural areas.For city-led rural counties,leveraging the“scale effect of urban areas to drive rural external development”is advised,focusing on“substituting industry for agriculture and facilitating urban-driven rural advancement.”The rural-promoted city counties should pursue a strategy of“agricultural upgrading and agriculture-driven industrial development”to stimulate urban enterprise growths through the agricultural value chain expansion.For contraction-reconstruction counties,the“optimal and sustainable development”approach is proposed to explore orderly rural reconstruction and ecological value transformation.
