城市化与人口的自然控制

城乡不同的社会保障制度、养育子女的机会成本、不同的生产方式、社会管理水平等会影响生育意愿和生育偏好,导致不同的生育控制结果。中国的人口控制已经陷入一个怪圈,即越是拒斥人口的城市转移,就越使农村人口过快增长,使城市化所具有的人口自然控制功能无法实现。因此,政府应当通过发挥城市的规模经济效应,平衡不同规模城市的财政投入,积极稳妥地推进城市化,最大限度地实现人口的自然控制。

Natural Control of Population in Urbanization

Different urban and rural social securities, different costs of upbringing children, different mode of production as well as different social management can influence not only fertility desire and preference but also the result of population control. The current population control in China has been thrown into a dilemma in which the stricter measures the cities take to control rural migrants, the faster increase of rural population the cities have. As a result, urbanization lost its function of natural control of population. In fact, natural control of population can achieve a higher level by the government＇s exerting the influence of scale economy, balancing fiscal expenditure of different--size cities and carrying out an active and pru- dent urbanization policy.
