Sample Rotation Design Urban Housing Vacancy Rate

China’s urban housing vacancy phenomenon already evident about 2003, but the survey on housing vacancy rate has been no official authority of the institution to its official description, the housing vacancy rate for the survey has been an important concern of the people topic. Survey of urban housing vacancy rate is an important continuity of the international investigation, as an important indicator of the real estate market, it is related to the national economy and an important socio-economic survey, if the city’s housing vacancy rate is so calculate and seasonable that it can reflect an efficient market supply gap between the market and effective demand. Survey on housing vacancy rate has become a mature and stable sampling project in the world, including sample rotation technique is an important theoretical basis. Our housing vacancy rate for the survey is still in an exploratory phase of the experiment, the development of China’s economy has gradually stabilized, under the premise of the gradual deepening of social reforms in the investigation of urban housing vacancy rate how successful application of sample rotation technique is the survey department urgent theoretical problem solution.As the continuity of the socio-economic survey of the process of urban housing vacancy rate in the sample problem of aging is difficult to avoid, but scientific and rational application of sample rotation sampling techniques can effectively solve the problem of the aging process of the sample, and to meet the objectives of the survey sample while also able to significantly improve the accuracy of a sample survey to improve the quality of survey data.This paper investigated the rotation of the sample at home and abroad about the theory and the international community about the urban housing vacancy rate, and summarized the basic theory of the sample rotation, rotation of three commonly used methods of sample models and practical application are discussed in detail analysis. The actual investigation based on this combination of urban housing vacancy rate, depending on the purpose of the investigation, on the basis of single horizontal sample rotation pattern based on the design of sample rotation model for the proportion of the target amount under stratified sampling, and detailed results prove; socio-economic survey in the continuity of the start, was constructed in three stages for three levels of long-term survey sample rotation model of urban housing vacancy rate survey, namely 12-6-12 (24in),6-12 -6 (12in), 3-15-3 (6in) mode, sampling theory survey of China’s urban housing vacancy has made a theoretical breakthrough.
