Based on the micro survey data of 419 registered poor households in five provinces of central and Western China, the confidence of registered poor households to get rid of poverty is calculated. At the same time, using the ordered logit regression model, the influencing factors are analyzed from the sustainable livelihood capital of poor households and the cognition and evaluation of poverty alleviation policies. The empirical results show that: Most of the respondents are more confident about getting rid of poverty, while only 8.96 percent are less confident, and 10.17 percent are very unconfident. Poor households that have no confidence in getting rid of poverty are the main body of "waiting, relying and wanting". The healthier the household head, the greater the confidence of getting rid of poverty. Householders with skills training are more confident that they will be lifted out of poverty. Reasonable human contact expenditure helps to increase the confidence of getting rid of poverty, but the more the human contact expenditure exceeds the reasonable limit, the less confidence the poor households have in getting rid of poverty. The poor households with a high level of understanding of national poverty alleviation policies have greater confidence in getting rid of poverty. The poor households who believe that poverty alleviation resources are distributed fairly have greater confidence in getting rid of poverty. The poor households with high satisfaction with the implementation of the policy have greater confidence in getting rid of poverty.
