【摘要】：人口要素与经济要素的研究不止要素与要素之间的分析,他们是相互渗透,相互影响的,因此对系统与系统之间关系的研究是必要的。本文主要分析人口特征系统和经济特征系统的关联关系,基于历年的统计数据和2015年1%人口抽样调查数据,采用探索性的数据分析方法,利用折线图、散点图、柱状图等分析人口和经济的基本特征,利用探索性空间分析方法分析人口和经济在空间分布上的状况,提取人口和经济的特征要素系统,最后通过灰色关联分析、典型相关分析探讨了人口特征系统和经济特征系统的关联关系,并探讨了人口聚集效应和产业结构,人口重心迁移和经济重心迁移的关系。研究发现,四川省经济进入了新常态的状况下,人口也进入了不同以往的新常态。例如四川省人口已经进入老龄化状态并有加重的趋势,城镇化率加深、人口流动加快等特征。同时人口分布“东密西疏”的特征,和经济呈现“东强西弱”的特征具有一定程度的关联性,并通过灰色关联分析得到了验证,具体呈现在劳动人口数和人口不均衡指数两个特征与居民消费价格指数这一经济要素关联性强;城镇人口比重、老年人口比重和人口自然增长率三个特征与四川省人均纯收入这一经济要素关联性强;人口总数与第三产业这一经济要素的关联性强等关系。人口分布的均衡性对经济的影响最大,并通过人口聚集效应和产业结构分布关系,人口重心迁移和经济重心迁移关系得到验证。
[Abstract]:The study of population and economic factors is not only the analysis of elements and elements, they are mutual penetration and mutual influence, so it is necessary to study the relationship between system and system. This paper mainly analyzes the relationship between population characteristic system and economic characteristic system. Based on the statistical data of past years and the data of 1% population sample survey in 2015, this paper adopts exploratory data analysis method, using broken line map, scattered plot diagram. Histogram is used to analyze the basic characteristics of population and economy, the exploratory spatial analysis method is used to analyze the spatial distribution of population and economy, and the system of characteristic elements of population and economy is extracted. The relationship between population characteristic system and economic characteristic system is discussed by canonical correlation analysis, and the relationship between population concentration effect and industrial structure, population center of gravity migration and economic center of gravity migration is also discussed. The study found that Sichuan's economy has entered the new normal and the population has entered the new normal. For example, the population of Sichuan Province has entered the aging state and has the tendency of aggravation, the urbanization rate is deepening, the population flow is quickening and so on. At the same time, the characteristics of population distribution "East Mixi sparse" and the economic characteristics of "east strong west weak" have a certain degree of relevance, and are verified by grey correlation analysis. In particular, there is a strong correlation between the two characteristics of the labor force and the population imbalance index and the economic factor of the consumer price index; the proportion of the urban population, The proportion of the aged population and the natural growth rate of the population are closely related to the economic factor of per capita net income of Sichuan province and the relationship between the total population and the tertiary industry. The equilibrium of population distribution has the greatest influence on the economy, and it is verified by the relationship between population concentration effect and industrial structure distribution, and the relationship between population gravity center migration and economic gravity center migration.
