适度人口理论与适度流动人口

Theory of Moderate Population and Moderate Mobile Population

人口流动效率与流动人口规模高度相关,流动人口效率也同样存在流动人口规模效率递增、流动人口规模效率不变和流动人口规模效率递减三个规模效率状态。流动人口是社会总人口的一个构成部分,有适度人口就必然有适度流动人口,决定一个国家适度流动人口规模P的主要决定因素是社会总人口G、制度自由度S、比较收益差别C、实际流动人口A、失业人口U、其他变量N,适度流动人口的基本函数方程式就是:P=f(G,S,C,A,U,—N)。中国适度流动人口=现有显型失业人口+城乡隐型失业人口+每年新增劳动力人口-新吸纳就业人口,这些流动人口是现有的符合效率要求的实际流动人口的存量和增量之和。

The efficiency of mobile population that highly relates to the pattern of mobile population, at the same time, consists of three pattern efficiency states concluding progressive increase, invariable and successive decrease. Mobile population is a section of the social general population. Moderate mobile population inevitably accompanies moderate population. The pattern of moderate mobile population(P) in a country is mainly determined by the social general population(G), the unrestricted degree of the system(S), the difference of the comparative profit(C), the actual mobile population(A), the unemployed population(U) and the other variables(N). Moderate mobile population of China=the current explicit unemployed population+the implicit unemployed population in the city and town + the incremental labor force every year - the absorbed employed population recently. Mobile population contains the stock and the increment of the actual mobile population that conforms to the demands of efficiency.
