Measuring Inequality of Bus Service Between Urban and Rural Areas Based on Decomposition of Gini Coefficient:A Case of Haining City in Zhejiang Province
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.
