An Analysis On Distribution And Its Influence Factors For Population In China

China has a population of about1300000000, mainly in the southeastern coastalprovinces, this is natural, social and economic factors long-term effect. With thedevelopment of regional economy and large-scale population flow, as of2010, China'spopulation distribution state is still the east part of area population occupies proportionis the largest, followed by the central and Western regions. Our country populationdistribution was presented the stability and the unevenness of the characteristics, presentthe pattern of population distribution was reasonable. What is the Impact factor toChina's population distribution, and how much it is, research on China's populationdistribution and its influence factors, to master our country population distributionpattern, population trend, so as to formulate the effect of population distribution ofrelevant policies, all has the important practical significance.The article with our country31provinces urban district as the research unit,according to the1982China Statistical Yearbook,1991China Statistical Yearbook,2000Fifth National Population Census and the2011China statistical yearbook data, summedup from the early Republic to2010our country population distribution. And using theSPSS statistics software in single factor correlation analysis, principal componentanalysis, multiple linear regression analysis method, the population density to reflect thedistribution of the population of the dependent variable, to the natural, social andeconomic factors of the31indicators as independent variables, the effect of populationdistribution of factors were analyzed quantitatively, the single factor correlation analysisof main observation the factors and the population density of the correlation coefficientsize, thereby determining which type of factor and population distribution of therelationship between the maximum. Principal component analysis is mainly throughdimensionality reduction approach, originally31indicators for5factors, namely, easycalculation and avoid the indicators are high correlation and give the negative influence.Using multiple linear regression is obtained by calculating the correlation index andpopulation density of the regression equation, analyses main index of population density affects the size of.Analysis results show that, in the natural factors, social factors and economicfactors, economic scale and distribution, average per capita consumption and industrialstructure, the culture quality of life, labor participation, the agricultural developmentlevel of population density has great influence, especially the per capita GDP andemployment in urban units average population density is the greatest impact. Finally,summing up the above analysis result, predict the future with the regional economicdevelopment, especially the old industrial bases in Northeast China and the rise ofwestern big development strategy of the project put into operation, will make localeconomy actual strength jumped up, induct population will substantially increase, ourpopulation distribution pattern there will be relatively large difference.
