| 中文摘要: |
| 精准识别贫困对象是客观、科学进行扶贫的重要基础。20世纪90年代以来,我国经历了扶贫开发的三个阶段,确定了592个国家级贫困县。 评定过程受到哪些因素的影响等,都是需要正视的问题。 基于此,文章使用 DMSP / OLS 夜间灯光数据,对贫困县的评定结果进行检验与分析。 研究发现:总体上非弱夜间灯光密度的贫困县数超过四成,这一偏误具有地区差异性;产生偏误的主要原因是“老少边”政策因素与领导人“关系上的照顾”产生的交互作用。 |
| 英文摘要: |
| The accurate poverty evaluation is an important basis for objective and scientific poverty alleviation. Since 1990s, China has gone through three stages of poverty alleviation and identified the state-level poverty-stricken county. Whether the evaluation result is objective, fair and reasonable, it is a problem that needs to be squarely faced. Based on this, we use DMSP / OLS night-time light to test and analyze the evaluation results of the national poverty county. We find that (1) in general, the number of the national poverty county with non-weak average night-time light has been over 40%. (2) The biased errors of the poor evaluation in the northeast, western and central regions are more obvious. (3) The main reason for the biased errors is the interaction between the policy factors which take care of the old revolutionary base areas, minority nationality regions as well as frontier areas, and the leade’爷s factors. |
