| 中文摘要: |
| 研究目标：测度中国城乡相对贫困与弱相对贫困指数并进行分解，明确影响城乡相对贫困变动的因素。研究方法：将2002~2020年城乡居民收入分组数据还原为观察值与GQ模型拟合洛伦茨曲线结合测度城乡相对贫困指数，并将测得指数分解为四种效应。研究发现：农村相对贫困指数与弱相对贫困指数均高于城镇，且城乡相对贫困指数有上升趋势，城乡弱相对贫困指数呈下降趋势。分解结果表明，增长效应对城乡相对贫困指数和弱相对贫困指数变动起负向作用，贫困标准效应对城乡两种指数变动起正向作用。分配效应与城乡两种指数的变动一致，人口效应对城镇两种指数变动的作用为正，对农村两种指数变动的作用为负。研究创新：将影响相对贫困变动的因素扩展至人口效应和贫困标准效应，认为影响相对贫困与弱相对贫困变动的因素有增长效应、贫困标准效应、分配效应和人口效应四种。研究价值：为城乡相对贫困的测算与分解提供新的思路，为建立解决相对贫困的长效机制、推进共同富裕提供依据。 |

| Research Objectives: To measure and decompose the relative poverty index and weak relative poverty index of urban and rural areas in China, and to clarify the factors influencing the change of urban and rural relative poverty. Research Methods: The income data of urban and rural residents from 2002 to 2020 were restored to the observed value and the lorenz curve fitted by GQ model to measure the relative poverty index of urban and rural areas, and the measured index was decomposed into four effects. Research Findings: The rural relative poverty index and weak relative poverty index are higher than urban, and the relative poverty index of urban and rural areas shows an upward trend, while the weak relative poverty index of urban and rural areas shows a downward trend. The decomposition results show that the growth effect has a negative impact on the changes of urban-rural relative poverty index and weak relative poverty index, and the poverty standard effect has a positive impact on the changes of urban-rural relative poverty index and weak relative poverty index. The distribution effect is consistent with the changes of urban and rural indices. The population effect has a positive effect on the changes of urban indices, and a negative effect on the changes of rural indices. Research Innovations: The factors affecting relative poverty change are extended to population effect and poverty standard effect, and it is considered that there are four factors affecting relative poverty and weak relative poverty change: growth effect, poverty standard effect, distribution effect and population effect. Research Value: It provides a new idea for the measurement and decomposition of urban and rural relative poverty, and provides a basis for the establishment of a long-term mechanism to solve relative poverty and promote common prosperity. |
