| 摘 要： | 针对扶贫领域中贫困、脱贫和返贫状态预测不准确，影响状态变迁的关键因素难以识别的问题，从扶贫基础数据和多个行业数据中提取8个关键特征和22个观测状态，构建观察状态和隐含状态关联关系，建立扶贫对象状态预测隐马尔可夫模型(hidden markov model,HMM)。以某深度贫困县连续3年的数据为样本，进行参数训练、测试实验和结果验证，结果表明该方法对返贫、贫困和脱贫状态有较强的预测能力，误差率较低，且能准确识别出影响返贫的关键要素。该方法对指导精准扶贫工作具有非常重要的实际意义。

| Abstract: | In order to solve the problems of inaccurate prediction of poverty, poverty reduction and poverty returen, and the difficulty in identifying the key factors affecting the state transition, 8 key features and 22 observed states are extracted from the poverty reduction basic data and multi-industry data. The relationship between observed state and implied state is constructed, and the hidden markov model (HMM) of poverty alleviation is established. Data of a deep poverty county for three consecutive years are used as samples for parameter training, test experiment and result verification. The results show that the method has a strong prediction ability for back poverty, poverty and poverty alleviation with low error rate, and can accurately identify the key elements affecting poverty return. The method is of great practical significance for guiding the precise poverty alleviation work. |
