Abstract: In the research of sampling theory and application, China has been more emphasis on the sampling scheme design, and ignored the study about sampling estimation method. In this paper, on the basis of successful experience systematically from Canada and other western countries, a set of generalized regression estimation system is introduced and improved, and applied to the complex successive multistage sampling survey, in order to lay a theoretical foundation for the application of China’s sampling estimation. Taking the China’s crops multistage sampling survey as an example, we give a set of specific regression estimation procedures in order to verify this system's practicality and application value.
