摘要: 摘  要:基于中国省域2007~2016年面板数据,重构了城乡一体化水平评价指标体系,运用熵值法对中国城乡一体化水平进行了测度,并通过趋势面分析、空间自相关、门槛模型研究了中国各个省市城乡一体化水平的时空格局演变特征与影响因素。研究发现:中国城乡一体化水平在“城乡空间、城乡经济、城乡社会、城乡文化、城乡生态”5个维度中稳步上升,区域差异呈现出“两升一降”的“N”型变化趋势;地区间发展不平衡,即在东西方向上存在较为稳定的“东高西低”的空间趋势,在南北方向上存在“两端低中间高”的空间趋势;城乡一体化水平全局上表现出空间集聚特征,局部上城乡一体化水平热点区和次热点区主要集中在中国的东部地区和东南沿海的省市,冷点区主要集中在中部和西部地区;城乡收入差距和政府行为均对城乡一体化水平具有显著的双门槛效应。

Abstract: Abstract:This paper based on the panel data of China’s provinces from 2007 to 2016, the evaluation index system of urban-rural integration level was reconstructed, and the level of urban-rural integration in China was measured by entropy method. Then through the trend surface analysis, spatial autocorrelation and threshold model to study the spatio-temporal characteristics of urban-rural integration and its threshold effect in China. The results show that: the level of urban-rural integration in China has steadily increased and in the five dimensions of “urban-rural space, urban-rural economy, urban-rural society, urban-rural culture, urban-rural ecology”, and the regional differences have shown an “N type” change with the trend of “two rises and one decline”. There is an unbalance between regions with a relatively stable spatial trend of “East high and low west” in the east-west direction, and a spatial trend of “lower intermediate heights at both ends” in the north-south direction. The level of urban-rural integration shows the characteristics of spatial agglomeration on the whole. The locally urban-rural integration level hot spots and sub-hot spots are mainly concentrated in the eastern part and the southeast coast provinces of China, the cold spots area is mainly concentrated in the central and western regions. The urban-rural income gap and government behavior all have a significant double threshold effect on the level of urban-rural integration.
