重庆城市居民生活质量演变及其影 响因素研究

Temporal and Spatial Patter ns and Its In flue ncing Factors of the Quality of Life of Residents in Chongqing

随着社会经济的转型与城市建设内涵式发展,居民生活质量在城市发展中所受到的关注正逐步提升。在重新界定居民生活质量内涵的基础上,运用变异系数、空间自相关分析及地理探测器等方法,分析2006-2016年重庆城市居民生活质量时空演变特征,并探讨居民生活质量的主要影响因素及其作用机制。结果表明:(1) 2006-2016年重庆市居民生活质量整体提升25.85%,各区县间居民生活质量差异减小;(2) 2006-2016年重庆市居民生活质量呈现"西高东低"的空间梯度分异特征,渝西地区出现稳定的高值集聚区,低值主要集聚在渝东北与渝东南两大区域;(3)经济状况、城镇化水平、政府管理是导致居民生活质量差异化的重要因素,产业结构的作用强度下降,自然地理特征的作用不显著。

With the transformation of social economy and the connotation of urban construction,the concern of residents'quality of life in urban development is gradually increasing.The paper is based on the evaluation index system of residents*quality of life,using the coefficient of variation,exploratory spatial data analysis and GeoDetector methods to analyze the spatial and temporal evolution of regional differences in the quality of life of residents in Chongqing from 2006 to 2016,and discusses the main influencing factors of residents*quality of life and their mechanism of action.The results indicate that:(1)The quality of life of residents in Chongqing increased by 25.85%from 2006 to 2016,and the overall difference in the quality of life of residents in various counties saw a decrease.(2)The quality of life of Chongqing residents in 2006-2016 was at medium high.The number of counties of the high grades increased significantly,and the overall layout of residents'quality of life showed the spatial gradient differentiation characteristics of"west high and low east".The high value is mainly concentrated in the western part of Chongqing,while the low values are mainly concentrated in the northeast and southeast regions of Chongqing.(3)Economic status,urbanization level,and government support are important factors influencing regional differences in residents'quality of life.The intensity of industrial structure is gradually decreasing,and the role of topography is not significant.
