摘要
This paper reviews the background of China’s decision to launch the“China Migrants Dynamic Survey”(CMDS),and examines the ideas and characteristics of CMDSs carried out annually from 2009 through 2018.The paper considers such aspects as project design,questionnaire design,sampling design,and survey imple-mentation,and summarizes why it is necessary to carry out CMDS and the survey’s performance.Based on the need for information that drives migration surveys and research in the new era,and taking into account the experience gained from previous surveys,this paper attempts to set forth several issues that need to be taken into con-sideration in the design and implementation of future surveys of migrants.
