A classification, identification and analysis method for floating population based on mobile phone big data

Abstract

The invention provides a method for classifying, identifying and analyzing floating population based on mobile phone big data. The present invention breaks through the limitations of traditional surveys, uses big data to extract objective spatio-temporal information from behavioral trajectories for analysis and mining, breaks through the limitations of low sampling rates and can perform multiple and sufficient information extractions of different calibers, from the dimension of space and time, population flow Conduct observation and identification, distinguish floating population groups, and consider the different classifications of floating population based on the behavioral characteristics and length of stay of the group, and from the perspective of data users, and divide them into long-term floating population, short-term floating population and short-term immigration population, So that the application of this data can play a role in different fields.

Description

technical field [0001] The present invention relates to a method for classification, identification, mining and analysis of floating population in a big data environment based on massive anonymous and encrypted mobile terminal individual (such as independent mobile terminal such as mobile phone, tablet, internet card, etc., hereinafter referred to as individual) data. This method measures the classification and identification of different types of floating population based on the spatial displacement and its duration caused by the flow of people, and further obtains the distribution and travel characteristics of this type of population based on this. Planning and management, business planning and other work provide objective data services and decision-making support, which belongs to the technical field of urban operation management, urban planning, and regional planning. Background technique [0002] Floating population is a concept under the condition of China's household ...

Problems solved by technology

At the same time, the residence of the floating population is relatively unstable, and it is very difficult to conduct interviews through household surveys

On the other hand, since the household survey is a one-time survey, with the adjustment of the survey content and the change of the statistical caliber, such as the 1982 and 1990 censuses: "cross-county" and "more than one year" floating population; In 1995, the floating population of “inside the county” and “more than half a year” were further identified; the 2000 census: the screening of the population of “separation of households in the city”; in 2005, the investigation of the inflowing population who left the place of residence registration for less than half a year was added, see Causes of Floating Population There are huge differences in quantity and scale, and it is impossible to continuously track and compare them in depth
