Study On The Optimum Population,Evolvement And Characteristic In City And Its Districts

At present, the problem that what the optimum population of a city should be has became the core problem of city development. Seemingly, people focus on the problem of population capability or scale, however, they actually concentrate on the influences on practical problems such as local economy, transportation, social security, education, medical care, etc. caused by population, from the deep perspective. Further speaking, the more serious problem is that how to distribute the optimum population into the each district after the optimum population is determined, which plays a decisive role in final realization of the city population development.Taking Shenzhen and its districts for example, this paper is dedicated to analyze the population evolution and characteristics in Shenzhen and its districts from many perspectives such as population capability, population distribution and re-distribution, using the comprehensive method which is composed of many subjects such as population and economy theory, land resources theory, project system engineering, simulation technology, mathematical economics, spatial data mining and so on, and applying many analysis methods such as inverted system technology, P-S algorithms, actuarial technology, spatial statistical analysis, etc. into the analysis in complicated system of population, society, resource and environment.The innovative points of this paper include:1. On the basis of multi-objective decision making analysis, this paper deeply analyzed and revealed the population development problem and the major characteristics in Shenzhen and its districts, applying the advanced theory methods in many subjects. This paper also advanced the "six plus one" districts (including Guangming district) population distribution plan which was the most optimum plan in Shenzhen, and creatively concluded that the model of "regional unbalanced regulation" should be applied in future district regulation, and the specific implementation plan was also recommended in this paper. 2. Focusing on the harsh situation in future city population control in Shenzhen and the distinction in characteristics of population in each district and social and economic development, this paper creatively formulated the scientific, operational and feasible objective plans collection.3. Focusing on the statistical data of population from different sources, this paper prospectively stated that the statistical scope of actual management population in Shenzhen should be served as the reference value of regulation objective, which not only overcame the present research difficulties due to the different population scope, but constructed the quantitative foundation keeping pace of policies development of population management, services, industrialization update and optimization for the implementation of future household registration adjustment, regional functioning adjustment and optimized policies in our country.
