“精准扶贫”是打赢脱贫攻坚战的制胜法宝，在新时期巩固拓展脱贫攻坚成果阶段仍将发挥重要作用。精准扶贫战略实施的八年来，我国贫困地区经济发展取得长足进步，贫困家庭收入水平显著提升，贫困地区居民生产生活条件显著改善。但与此同时，我国贫困地区赖以生存的扶贫产业总体尚处于培育成长期，包括脱贫家庭在内的农村居民自我发展能力仍需进一步提升，患大病、慢性病农户与残疾人农户等特殊困难群体仍旧存在较大的返贫新致贫可能性。在脱贫攻坚取得全面胜利的大背景下，对河北省这个与全国农村整体发展水平十分相近的代表性省份进行精准扶贫绩效评估，不仅有利于从整体上把握精准扶贫战略实施成果及扶贫资源投入产出效率，深度探究精准扶贫过程中存在的问题，为巩固拓展脱贫成果、防止和减少脱贫农户大量返贫提供有益借鉴，还有助于从理论层面完善我国扶贫绩效评估体系，为开展后续研究提供一定的参考。

文章基于反贫困理论与先行扶贫绩效评估实践，将精准扶贫成果客观性指标和主观性指标相结合，充分考虑了经过精准扶贫后脱贫群众内生动力的变化，构建起包含财政扶贫资金、帮扶责任人两种投入指标和贫困地区农户增收、家庭生产生活变化、脱贫认可度及稳定增收等四项产出指标的精准扶贫绩效评估体系。在对河北省精准扶贫战略部署和扶贫成果进行深入解析后，文章运用灰色关联分析模型和DEA-BCC模型对河北省14个贫困县的精准扶贫综合效率、纯技术效率、规模效率进行测度。根据研究结果和调研材料，提出了提高扶贫绩效、巩固和拓展脱贫成果的政策建议。

精准扶贫绩效评估结果显示：第一，通过实施精准扶贫、精准脱贫战略，河北省贫困地区农民家庭生产生活条件得到显著改善，贫困户通过双手致富的能力与信心显著提升，为脱贫后持续稳定增入、不发生大规模返贫创造了基础。第二，灰色关联分析结果表明财政扶贫资金和帮扶责任人两项投入对贫困地区农户收入的持续增长作用十分突出。在未来的脱贫成果巩固拓展阶段，保持和加大乡村振兴补助资金规模与帮扶责任人帮扶力度是保证脱贫户不返贫的重要举措。第三，河北省部分贫困地区精准扶贫投入结构不甚合理，需要在脱贫成果巩固拓展阶段进行调整优化。结合绩效评估结果与调研材料，论文提出提升扶贫投入绩效，巩固拓展脱贫成果的政策建议：一是完善脱贫成果巩固拓展顶层设计，完善制度体系建设；二是精准识别巩固拓展对象，建立防返贫新致贫预警监测机制；三是优化扶贫投入结构，调整扶贫资源配置方式；四是完善救助保障机制，织牢织密防返贫保障网。

"Targeted poverty alleviation"（TPA） is the magic weapon to achieve comprehensive poverty reduction, and it will still play an essential role in consolidating and expanding the achievements of poverty reduction in the new era. In the eight years since the implementation of the TPA, China's poverty-stricken areas have made great progress in economic development, the income of poor families has been obviously increased, and the production and living standards of residents in poverty-stricken areas have been significantly promoted. But at the same time, the industry in poverty-stricken areas of China is still in the period of cultivation and growth, and the self-development ability of rural residents, including poverty-stricken families, still needs to be further improved, and there is still a greater possibility of returning to poverty and causing new poverty for farmers with serious diseases, chronic diseases and disabled people. Under the background of the overall victory of TPA, the performance evaluation of TPA in Hebei Province, which is a representative province with the overall development level of rural areas in China, is not only conducive to grasp the implementation results of TPA and the input-output efficiency of poverty alleviation resources, but also to explore the problems existing in the process of TPA, It also helps to improve the performance evaluation system of poverty alleviation in China from the theoretical level, and provides some reference for the follow-up research.

Based on the theory of anti-poverty and the practice of performance evaluation of poverty alleviation, this paper combines the objective index and subjective index of TPA, fully considers the change of endogenous motivation of the people out of poverty after TPA, and excludes the annual number of poverty reduction and other "political task" indicators from the evaluation system, so as to build a poverty alleviation system including financial poverty alleviation funds and the person in charge of helping and four output indicators of increasing farmers' income, changes in family production and life, recognition of poverty reduction and stable income increase in poverty-stricken areas. After deeply analyzing the strategic deployment and achievements of TPA in Hebei Province, this paper uses grey correlation analysis model and DEA-BCC model to measure the technical efficiency, pure technical efficiency and scale efficiency of TPA in 14 poor counties of Hebei Province. According to the research results and collected materials, this paper puts forward policy suggestions to improve the performance of poverty reduction, consolidate and expand the achievements of TPA.

The performance evaluation results of TPA show that: first, after the implemented of poverty alleviation strategy, the production conditions and living standards of farmers in poverty-stricken areas of Hebei Province have been significantly improved, and the ability and confidence of poor-alleviation households to get rich by themselves have been significantly improved, which has created a material foundation for the sustained and stable increase of family income after TPA without large-scale return to poverty talent foundation and ideological foundation. The second is the gray correlation analysis, which proves that the two input indicators of financial poverty alleviation funds and the person in charge of helping have a prominent effect on the sustained growth of farmers' income in poor areas. In the future of consolidating and expanding the results of poverty reduction, it is an important measure to maintain and increase the financial scale of Rural Revitalization subsidy funds and the person in charge of helping. Third, the input structure of TPA in some poverty-stricken areas of Hebei Province is not reasonable, so it is necessary to adjust and optimize the input structure in the consolidation and expansion stage of poverty alleviation achievements. Based on the results of research and materials of surveys, a top-level design for improving the performance of investment in poverty reduction is proposed to consolidate and expand the results of poverty reduction, and improve mergers and acquisitions and expansion, establish and improve the system; Accurately identify the group that need to be consolidated and expanded, and establish an early warning and monitoring mechanism to prevent new poverty; optimize the input structure for poverty alleviation and adjust the allocation of poverty alleviation resources; We should accelerate the relief and security mechanism, and firmly weave the anti-poverty security network.
