摘要: 探明城乡公共交通不平等来源及其变化特征对缩小城乡差距有重要意义,以浙江省海宁市为例,将站点可达性作为公共交通服务指标,以交通小区作为分析单元计算公共交通可达性,分别计算2011—2020年研究区域总体、城区、农村及城乡间的基尼系数,将总体基尼系数按城区和农村两个子群进行分解,分析城乡公共交通不平等来源及其演变特征。结果发现:总体基尼系数为0.7204~0.7736,城区基尼系数为0.5718~0.6058,农村基尼系数为0.5955~0.6390,城乡间基尼系数为0.8131~0.8710,研究区域公共交通严重不平等,城乡间不平等程度最大;2011—2020年间总体、城区、农村和城乡间的基尼系数分别下降了5.62%、6.88%、5.21%和6.65%,公共交通不平等不断改善;城乡间不平等对总体不平等的贡献率为63.03%~67.58%,是总体不平等的主要来源。研究表明,基尼系数分解能有效测度城乡公共交通不平等来源,缩小城乡间不平等是城乡客运均等化发展的重要任务。

Abstract: Investigating the factors that cause the inequality of bus service is essential to narrow the gap between urban and rural public transportation services. Taking Haining City of China as an example, this study uses the accessibility to bus services as an indicator of the public transportation services. Traffic analysis zones (TAZs) were used as units to calculate the accessibility to bus services. The Gini coefficients of the overall region, urban, rural and between urban and rural were calculated for the period from 2011 to 2020. The overall Gini coefficient was decomposed into urban and rural subgroups. The evolution of urban-rural inequality was analyzed. It was found that the Gini coefficient for the region ranges from 0.7204 to 0.7736. The Gini coefficient of urban area is between 0.5718 and 0.6058, the Gini coefficient of rural area is 0.5955 to 0.6390, and the Gini coefficient between urban and rural ranges from 0.8131 to 0.8710. The results indicate there is significant inequality of public transportation between urban and rural areas. However, the Gini coefficient of the overall region, urban, rural and between urban and rural decreased by 5.62% , 6.88%, 5.21% and 6.65% respectively from 2011 to 2020, which suggests the bus equality saw some improvements in the past years. The contribution of inequality between groups to the overall inequality ranges from 63.03% to 67.58%, which indicates the inequality between urban and rural contributes mainly to the overall inequality. The decomposition of Gini coefficient is an effective measure to analyze the regional inequality of public transportation. Improving the inequality between urban and rural is an important task to achieve an equitable regional public transportation.
