黔中城市群新型城镇化与农业现代化耦合协调对城乡收入差距的影响

Impact of coupling and coordination of new urbanization andagricultural modernization on the urban-rural income gapin the central Guizhou urban agglomeration

从新型城镇化与农业现代化协调发展的视角切入,探究“两化”协调发展水平与城乡收入差距的关联性,对统筹城乡发展、促进区域高质量发展具有重要意义。论文以黔中城市群为案例区,综合运用熵值-TOPSIS法、耦合协调度模型、探索性空间分析等方法,分析2010—2020年“两化”协调发展水平和城乡收入差距的时空格局,揭示了两者的时空关联性,并对影响城乡收入差距的其他因素进行了对比分析。结果表明:(1) 2010—2020年黔中城市群“两化”协调发展水平显著提高,协调类型由濒临协调为主转向勉强协调为主;期间城乡收入差距呈缩小趋势,县域间分化趋于收敛,但其差异仍旧明显。(2) 2010—2020年黔中城市群“两化”协调发展水平低值区主要位于西部毕节一带,高值区集中于中部贵阳;“两化”协调发展和城乡收入差距两者均具有显著的空间正相关性,城乡收入差距与“两化”协调水平的低、高值区存在较为明显的空间重合现象。(3) 2010—2020年黔中城市群“两化”协调发展水平对城乡收入差距有显著影响且呈增强态势;此外,人力资本水平、道路基础设施密度和教育水平等也是影响城乡收入差距的核心驱动因素,多因素综合作用形成了黔中城市群城乡收入差距空间格局。

From the perspective of coordinated development of new urbanization and agricultural modernization(NU-AM),this study explored the relationship between the level of coordinated development of NU-AM and the urban-rural income gap,which is of great significance for balancing urban and rural development and promoting high-quality regional development.Taking the central Guizhou urban agglomeration as a case study region,this study applied the entropy-TOPSIS method,coupling and coordination degree model,and exploratory spatial analysis method to analyze the spatial and temporal patterns of the coordinated development level of NU-AM and the urban-rural income gap from 2010 to 2020,revealed the spatial and temporal correlation between the two,and compared and analyzed other factors that affected the urban-rural income gap.The results show that:1)The level of coordinated development of NU-AM in the central Guizhou urban agglomeration has improved significantly,and the main coordination type changed from low coordination to moderate coordination.During this period,the urban-rural income gap showed a trend of narrowing,and the differentiation among counties tended to converge,but the differences were still obvious.2)The low-value areas of the coordinated development level of NU-AM in the central Guizhou urban agglomeration were mainly located in Bijie,and the high-value areas were concentrated Guiyang;both the coordinated development of NU-AM and the urban-rural income gap showed significant positive spatial correlation,and there was a clear spatial overlap between the low-and high-value areas of the urban-rural income gap and the coordination level of NU-AM.3)The level of coordinated development of NU-AM in the central Guizhou urban agglomeration had a significant impact on the urban-rural income gap and showed a strengthening trend;in addition,the levels of human capital,road infrastructure density,and education were also core driving factors that affected the urban-rural income gap.The combined effect of multiple factors has formed the spatial pattern of the urban-rural income gap in the central Guizhou urban agglomeration.
