基于武汉市、郑州市、北京市1 286份农民工样本调查数据，以城市归属感为中介变量，探讨身份认同对农民工城市定居意愿的影响，结果表明：身份认同对农民工城市定居意愿具有显著正向影响。在身份认同的五个指标中，农民工收入地位认同对城市定居意愿的影响最大，其次分别为生活方式认同、人际交往认同、自我角色认同、制度处境认同。身份认同不仅对农民工城市定居意愿有直接提升作用，而且可通过正向作用于城市归属感间接提升农民工城市定居意愿。身份认同对农民工城市定居意愿的影响具有代际差异。自我角色认同、收入地位认同、人际交往认同、生活方式认同对新生代农民工城市定居意愿的影响大于第一代农民工，而制度处境认同对第一代农民工城市定居意愿的影响大于新生代农民工。

Based on the sample survey data of 1286 migrant workers in Wuhan, Zhengzhou and Beijing, this paper explores the identity impact on migrant workers' willingness to settle down in cities with the sense of urban ascription as an intermediary variable. The results show that identity has a positive and significant effect on the migrant workers' urban settlement willingness. Among the five indexes of identity, migrant workers’ income status exerts the greatest influence on their urban settlement willingness, followed by the identity in lifestyle, interpersonal relationship, self -role and institutional situation. Migrant workers' identity not only directly motivates their desire to settle down in cities, but also indirectly intensify their urban settlement willingness through positive effect on the sense of urban ascription. Generation gap exists in the influence of identity on migrant workers' willingness to settle down in cities. Self identity, income status identity, interpersonal identity and lifestyle identity have a stronger impact on the urban settlement willingness of the new generation migrant workers than that of the first generation, while the institutional identity has a greater influence on the first generation migrant workers than that of the new generation migrant workers.
