Systematic study on Chinese city housing life cycle not only affects the adjusting and controlling of government scientific and formulating the policy of management housing industry, and affects the strategic strategy arrangement of the enterprises related to housing industry.This paper studies the influencing factor of Chinese city housing life cycle at first. From housing design working life, structural design and architectural design, the paper studied the influence of housing designed. From housing construction and housing manage policy analysis its influence for housing life cycle. From national economy, housing initial investment, housing space and the change of land use system, city and its population to discuss its influence for housing life cycle.Secondly, the economic life of Chinese city housing is studied. The life cycle cost theory is used to study the calculation of the housing life cycle cost analysis, and the calculation model of the housing life cycle cost is established. The calculation model of the housing economic life is set up used differently annual profit method, deterioration value method, and average cost method. Through sample analysis the length and characteristic of the economic life of Chinese city housing is gotten, and sensitivity analysis is carried out. On this foundation, refresh problem of city housing is studied, the calculation method of increasing and decreasing of housing refresh is discussed, and the decision method of city housing system refresh is studied.Then, the service life of Chinese city housing is studied. The housing structural type is regarded as the entry; study on the calculation of housing surplus service life is carried out. On this foundation the calculation principle of housing optimum surplus service life is discussed. Based on fuzzy assemble theory the forecast method of housing to be established service life is set up, and the related example is analyzed. The paper uses statistical analysis, Weibull model, life table and survival analyse to discuss city housing service life calculate model. Through sample analysis the length and characteristic of the service life of Chinese city housing is gotten.After it, the influential of housing life cycle are analyzed. This paper analyzed the social influential of housing life cycle from family consumer behavior, life cost and social network and social psychological. Through sample analysis the optimum service life of Chinese city housing is gotten. On the foundation of analyzing life cyle energy, the calculation model of the housing life cycle energy is established. Through sample analysis the characteristic of life cycle energy of Chinese city housing is gotten.At final the strategy that realizes housing long life and housing life cycle goal is studied. It is suggested designed the housing of long life with housing life cycle design, and through housing life cycle integrated management guaranteed the realization of housing life cycle goal. It is suggested through perfecting the legal standard of housing quality and perfecting housing function to believe system, guaranteed housing of high quality, and realized housing long life and housing life cycle goal. On the foundation of analyzing old housing to renew policy guarantee, method and the value of transform, it is suggested that through perfect city housing removed system, reduced housing not long life in artificial factor.
