With the rapid development of economic and social, the objects in the sampling survey flowing increasingly frequent. Traditional single sampling frame is difficult to cover the overall goal of mobility because of the high cost and the long process. This paper breakthrough the current sampling theory, extend the sampling surveybased on a single sample to the case based on multiple sampling frame, that the multiple sampling frame can cover the overall goal and can save the total cost of survey. This paper study deeply on three aspects of the multiple sampling frame:Firstly, this paper systemize the estimation methods of dual sampling frame in foreign countries, and using a simple estimation model to unify those methods, then compare those estimation methods based on the asymptotic variance expressions of unified estimate, In addition, divided the existing estimate into two categories based on whether imposed on the virtual decomposition of the overall sample in the estimation process. Then extend the existing estimate to the case of more multiplicity (greater than 2), unify the expanded estimate by a simple form which similar to the HT estimate, and give the corresponding variance formula. Finally, inadequate for a variety of estimation methods, put forward the general ideas to improve and the estimation method of multiple sampling frame based on the unit multiplicity. The simulation results showed that the unit multiplicity estimate has the higher efficiency and isn't affected by the wrong classification unit.Secondly, through the system studies on the estimation method of multiple sampling frame which under specific sample survey such as multiple indicators stratified sampling, two-stage sampling and continuous sampling, this paper can provide the theoretical basis for the sample survey based on the multiple sampling frame. This paper used estimation method of multiple sampling frame in the case of multiple indicators stratified sampling to conduct sampling design, to give the corresponding simple estimate and discussed the determination of sample size and the optimal allocation between layers;Specifically discussed the estimation methods of two-stage sampling under the multiple sampling frame, and using the optimization method to obtain the optimal sample weight coefficient and sample size; Using gross flow estimate to analyse the estimation of continuous sampling under the multiple sampling frame, gave the ML estimate in the case of simple random sampling and the PML estimate in the case of complex sampling.Thirdly, through a comprehensive analysis of the problems which impact the sampling frame in the statistical survey system, this paper puts forward the application of multiple sampling frame methods is necessary and feasible in China. This paper take the "Agriculture, Countryside and Farmers" sampling survey for example,the sampling survey systems of multiple sampling frame was established, as involving " Agriculture, Countryside and Farmers " issue in the actual investigation workers guidance on the sampling method.
