Abstract: How to accurately identify poor households and poverty alleviation households is a problem often encountered in poverty alleviation work. Appropriate deprivation indicators and reasonable weight setting can help reduce the blurring zone. Through the analysis of CFPS data in 2014, this paper firstly sorts out the indicators related to poverty one by one, then it conducts an analysis of the initially selected indicators with the project response theory, so as to determine the nine indicators which are appropriate in difficulty and clear in direction. Based on the difficulty of the indicator, the corresponding weights are set, and the contribution rate of each indicator is compared with the equal weight method, so as to sift the proportion of the needy families. It is found that the difficulty weight method can reduce the failures in reporting the poor families.
