摘要
后期扶持对水库移民人均可支配收入的提高有着重要作用。因此,定量分析后期扶持绩效,制定合理的规划建议具有重大现实意义。为了揭示投入指标对移民收入变化的滞后性影响程度,反映后期扶持实际绩效水平,用时差相关分析方法计算投入指标的滞后期,以此为基础构建了后期扶持滞后效应DEA模型。从移民素质、生产条件、资金投入3个方面,以GD省YF市的3个样本县为研究对象进行水库移民后期扶持绩效研究和滞后效应对比研究。结果表明:YF市移民后期扶持非DEA有效,综合效率平均值为0.931且规模有效率低于纯技术有效率,在县域上具有技术管理水平低、投入规模过剩等特点,不考虑滞后效应会导致各项效率均值下降0.5%~14.4%。研究结果较客观地反映了后期扶持状况,可以为移民后期扶持政策的实施、调整提供依据。
Late-stage support plays an important role in improving the per capita disposable income of reservoir immigrants.Therefore,it is of practical significance to quantitatively analyze the present situation of income increase supported by reservoir resettlement in the later period and formulate reasonable planning suggestions.In order to reveal the lag effect of input indicators on the change of migrant income and reflect the actual performance level of late support,this paper calculates the lag period of input indicators by time difference correlation analysis method,and establish a DEA model of late support lag effect.From three aspects of resettlement quality,production conditions and capital investment,three sample counties in YF Citing Province are taken as research objects to study the support performance and lag effect of reservoir resettlement in the later stage.The results show that the post-migration support in YF city is not DEA effective,with the average comprehensive efficiency of 0.931 and the scale efficiency lower than the pure technical efficiency.It has the characteristics of low technical management level and excessive investment scale in the county,and the average efficiency will decrease by 0.5%~14.4%without considering the lag effect.The results of the study objectively reflect the situation of support in the later stage,and can provide a basis for the implementation and adjustment of the support policies in the later stage of migration.
