This research develops specific goals,paths and strategies of urbanization in China upon analyzing the Chinese characteristics and future trends of urbanization.Urbanization will become basic national conditions of China′s future social development,which will have significant impacts on the sources and driving forces of future prosperity and development.However,current challenges in China’s urbanization are that population urbanization lags behind industrialization and land urbanization,and urbanization of the household registered population lags behind urbanization of the resident population.China′s urbanization development will be shifted from a pure speed approach to an approach combining speed with quality during the "Twelfth Five-Year plan" period,and the economic reform will enter into a new stage characterized by promoting in-depth urbanization and urban-rural integration.An urbanization model with Chinese characteristics would be developed by taking urbanization as the leading force in deepening the reform,directing at household registration system reform and employment promotion,enhancing urbanization quality,and promoting equalization of rural and urban public services.

This article develops a balanced-population development approach to the demographic transition theory,arguing that demographic transition is a process in which societies move from a low-level population balance to a high-level population balance.China has experienced two phases of demographic transition: a stage in which the demographic transition occurred ahead of economic development and a stage in which it interacts with economic development;and China needs to stride across two traps in the demographic transition process: a "high-child-dependency" tarp and a "high old-dependency" trap.Stabilizing moderately low fertility levels and enhancing quality of the population are among the fundamental tasks for the future.

Sex Ratio at Birth in China has exceded the normal range since 1980.While the Communist Party of China,and central and local governments have formulated comprehensive methods in order to curb its rising trend and bring it back to the normal level,the effect is trival.Existing methods tend to focus more on the formulation of laws and regulations prohibiting sex-selective abortion than on supporting strategies,and to pay more attention to the goals and tasks to be achived than to specific ways to implement the goals.In addition,isolated rules and regulations provided by different government branches outweigh more comprehensive rules and regulations.Hence,to more effectively control the sex ratio at birth,the government should adopt the following strategies: further facilitating socioeconomic development,establishing a sound old-age pension system,and improving relevant laws and regulations to curb ultra-sound check and sex-selecctive abortion without medical needs.On the other hand,the government should take no actions on birth planning policy,and on the changes of cultural traditions.
