户籍制度松紧程度的一个衡量

Measuring the Strictness of the Household Registration System

本文构建了户籍制度下的个人迁移决策模型。在此基础上。本文衡量了户籍制度的松紧程度，同时估计了个人是否要户口的意愿。文章通过排除变量解决了部分可观察性问题。并用两步估计法纠正了选择性偏差。文章的计量部分从2000年人口普查的抽样数据中选取了大专毕业及以上学历的男性劳动力样本，估计了户籍制度松紧程度和个人意愿水平。

This paper develops a migration model under China's household registration system and tries to measure the strictness of the system. The estimation involves partial observability and selectivity biases with multiple criteria. The paper uses variable exclusion to identify the model and thus solves the problem of partial observability. It then adopts a 2-step strategy to correct the selectivity bias. A sample of urban male with university or higher degrees is drawn from the 2000 population census data, and is used for the estimation.
