甘肃省城镇功能和乡村功能的融合发展与交互影响

摘要/Abstract

摘要：

城镇功能与乡村功能的互补共生，既是城乡融合的核心要义，也是破解城乡二元矛盾的关键路径。基于2011—2023年甘肃省市域面板数据，构建城镇功能与乡村功能评价体系，采用熵权TOPSIS法、三维核密度估计等方法分析城镇功能和乡村功能的时空演变特征，利用耦合协调度模型分析城镇功能和乡村功能的融合发展水平，通过联立方程模型揭示城镇功能和乡村功能的交互影响。结果表明：（1）甘肃省城镇功能和乡村功能均呈现上升趋势，城镇功能呈现“沿轴集聚、梯度分异”的空间格局，乡村功能呈现“东西差异、带状延伸”的空间格局。（2）甘肃省城镇功能和乡村功能之间的融合发展水平不断增强，且与城镇化水平具有空间趋同性。（3）甘肃省城镇功能和乡村功能之间存在交互强化作用。经济水平、政府调控和技术水平对城镇功能和乡村功能均具有促进作用，城镇资本要素和城镇劳动力要素对城镇功能具有正向作用，乡村资本要素和乡村劳动力要素对乡村功能具有正向作用。

Abstract:

The complementary and symbiotic relationship between urban and rural functions is the key to integrated urban-rural development as well as the pathway to alleviating the urban-rural dual contradiction. Panel data at the city scale in Gansu Province from 2011 to 2023 were utilized. First, the evaluation system for urban and rural functions has been constructed. The entropy weight TOPSIS method and three-dimensional kernel density estimation were used to identify the spatiotemporal characteristics of the evolution of urban and rural functions. Second, the coupling coordination model was used to analyze the degree of integration development of urban and rural functions. Finally, the simultaneous equation model was used to reveal the interaction between urban and rural functions. The results show that: (1) Both urban and rural functions exhibit an upward trend in Gansu Province. The spatial distribution of the urban function showed pattern of axis-aligned agglomeration and gradient differentiation, while rural functions showed pattern of east-west disparity and belt-like extension. (2) The integrated development between urban and rural functions is continuously strengthened in Gansu Province, demonstrating spatial congruence with urbanization progress. (3) A positive interaction was observed between urban and rural functions in Gansu Province. The economic level, government regulation, and technical level all had a promoting effect on urban and rural functions, urban capital elements and urban labor factors had a promoting effect on urban functions, and rural capital elements and rural labor factors had a promoting effect on rural functions.
