【摘要】：自大中型水库移民后期扶持政策实施以来,后期扶持效果监测评估工作稳步推进中。但截至目前,尚未建立统一规范的评价指标体系,缺乏科学、统一、规范的监测评估标准,对移民后期扶持的效果难以定量地做出综合评价。因此,需要对移民后期扶持效果综合评价进行深入的研究,积极探讨一种科学、客观、准确的评价体系方法。本文在水库移民后期扶持监测评估的基础上,结合各省市地区后期扶持监测评估工作实践,对水库移民后期扶持效果综合评价进行了深入探讨,并取得了以下主要成果:一是基于管理学、经济学、社会学等理论,分析了水库移民的现状、特点和原因,后扶政策实施的主要内容和形式、实施现状和存在的问题;二是在水库移民后期扶持监测评估的基础上,对水库移民后期扶持效果综合评价的内容、方法、作用及必要性进行了详细地阐述;三是提出了后期扶持效果综合评价指标体系,对水库移民后期扶持效果综合评价指标体系进行了系统全面的分析和量化评价;四是介绍了基于BP神经网络模型的水库移民后期扶持效果综合评价方法,并通过实例说明该方法的评价步骤,通过实证分析得出评价结果与实际情况良好吻合,验证了该评价方法的可行性。上述的研究成果可对以后如何改善移民的生活水平提供合理化建议,为完善后期扶持政策提供决策依据。具有可操作性和实用价值。
[Abstract]:Since the implementation of the support policy in the later stage of the large and medium-sized reservoir resettlement, the monitoring and evaluation of the later support effect has been progressing steadily.But up to now, there is no unified and standardized evaluation index system, which is lack of scientific, unified and standardized monitoring and evaluation standard, so it is difficult to make a quantitative comprehensive evaluation of the effect of support in the later period of immigrants.Therefore, it is necessary to make a deep study on the comprehensive evaluation of the support effect in the later stage of immigration, and actively explore a scientific, objective and accurate evaluation system method.On the basis of the monitoring and evaluation of the late support of reservoir resettlement, combined with the practice of monitoring and evaluation of the later support in the provinces and cities, the comprehensive evaluation of the late support effect of the reservoir resettlement is deeply discussed in this paper.The main achievements are as follows: firstly, based on the theories of management, economics and sociology, this paper analyzes the present situation, characteristics and reasons of reservoir migration, the main contents and forms of the implementation of the policy, the present situation and the existing problems;Secondly, on the basis of monitoring and evaluation of the later support of reservoir resettlement, the contents, methods, functions and necessity of comprehensive evaluation of the late support effect of reservoir resettlement are elaborated in detail; third, the comprehensive evaluation index system of the late support effect is put forward.The comprehensive evaluation index system of the later support effect of reservoir resettlement is systematically analyzed and quantitatively evaluated. Fourth, the comprehensive evaluation method of the later support effect of reservoir resettlement based on BP neural network model is introduced.An example is given to illustrate the evaluation steps of this method. Through empirical analysis, it is concluded that the evaluation results are in good agreement with the actual situation, and the feasibility of the evaluation method is verified.The above research results can provide reasonable suggestions on how to improve the living standard of immigrants in the future, and provide decision basis for perfecting the supporting policy in the later period.It has operational and practical value.
