The Total Population Planning Of Nanjing City

The development of population and city economy are closely linked, directly affects the development of prosperity and social economy. Population planning is base on the population forecast, according to the national economic development and population policy, population development of different period in a given area, develop specific control objectives and specific requirements and the corresponding measures. A very important content, is a region in different periods of the natural population growth and mechanical growth, the provisions of a specific control number. Population planning is the embodiment of national population policy, is implementing the powerful tool of population policy. While the population prediction is the basis of population research, is the product of social and economic development, political and economic development of each country or region and other social life is closely related with the change of population. Population prediction is developed and successfully based on the practice of all kinds of social economic strategy idea and starting point, is to formulate correct population policy scientific basis.. Therefore, there is important influence on the future development of a country or region. While the population forecasting is a necessary prerequisite for social and economic development projects planning and reasonable. So, the trend of the population development is the basis for the formulation of national economic and social development of the things.The population of city planning is about city population during a certain period of time (not including the suburbs and city, county) the basic conception of development scale, the short-term and long-term city population, also known as the city population planning. City population scale of development is the foundation of index of city planning, but also an important part of city planning. It influences and restricts the size of land, layout, service facilities and the city, city transportation way and the road network structure, related to the city construction development and economic effect. To develop city population scale of development, should be based on the city of city economic development strategy, the national economy development and the city of their own conditions, and consider reasonable to meet the problems of labor structure of city development of labor demand and reasonable arrangement.A variety of factors according to the current population, Nanjing’s forecast of total GDP, prediction, city population scale city rate prediction, the urban population forecast, the need for a more scientific and reasonable method, so as to grasp the law of development of Nanj ing’s population, which is adapted to the development of population and economic development of the city, to better meet the people’s growing material and cultural. At the same time, provide specific quantitative indicators for development planning of Nanjing city population and long-term development strategy, to provide basic support for other topics related to population and development planning of Nanjing City, the scale, structure, Nanjing City, the relevant departments to provide future population changes development planning of distribution and other specific data.According to the overall planning of Nanjing City, recently to2015, forward to2020, before and after the prospect to2030and2050, in building a higher level well-off society comprehensively, take the lead in basically realizing modernization, based on the important center city of Yangtze River Delta, East and West, toward the development of modern international humanitarian green the objectives of the strategy. Prediction method through the queue factor method in this paper using the scene, China population and development research center leading R&D international population prediction software (PADIS-INT), using the relevant data of the sixth population census of Jiangsu province in Nanjing City, in2010for the prediction of the base year, the design of low, medium, high, for the next40years in Nanjing city total resident population, birth, death, aging population and labor population change trend was predicted and analyzed. In this foundation, still is forecasted in2010as the base year, the design of low, medium, high scheme, using linear regression model to predict the total GDP of Nanjing city in the future40years, regression model to predict the future20years in Nanjing city of index by logarithmic curve, and then get the future40years of Nanjing city’s per capita GDP and future20years of the urban population size; analysis and evaluation and the predicted results.
