The population is the basic units of social development, the application of advanced technologies and methods from population data can dig out a lot of very useful information for us. Mastery of such information can play an important guiding significance in the proposed government policy for social development. So, the important direction of today’s population research is how to tap the maximum quantity message which inherent in the population data. The center of gravity and sensitivity which is the physics concepts, introduced into the population and economy study has become a widely accepted research methods, researching gravity center of a regional population and economic add the sensitivity analysis between population and economic can be the basic situation of the regional development of understanding and further to understand the development differences between regions, but also can migrate contrast population and economic center of gravity, combined with changes in the distribution of population and economic development, revealing the existence of the regional development inherent laws. To some extent, there is a mutual restraint and the relationship of mutual influence from the overall analysis, between the distribution of the population and the economy. Based on the regional center of gravity and sensitivity of the theory, application of GIS technology analyzes the relationship between population gravity center change and the migration of economic in Shanxi Province.Based on the population and economic center of gravity20years of Shanxi migration data for comparison, analysis of the interaction mechanism among the population, economic and industries in Shanxi, and as a basis for the coordinated development of Shanxi population and economy, industry optimal allocation of resources to achieve social stability and development recommendationsThe main results are as follows:(1)In the last23years (1989to2012), the population gravity center of Shanxi Province have been distributed in the Pingyao county,the first showing a trend to move towards the southwest, the inflection point in1999, began moving to the northeast; surrounding the distribution of economic gravity is concentrated in Shanxi Miyuan,Jiexiu and other places, every year there is a big shift.The economic gravity center of Shanxi outset has been to move towards the southwest, but after2004, economic center of gravity began to shift to the northeast, the focus was compared with the population, although both mobile trends are similar, but the time to turn of the population gravity center is five years later than the economic gravity, which indicated the relative economic development of Shanxi Province with a certain lag in terms of population change.In these years the primary industry did not exhibit the same tendency to move, but has been relatively stable like a circular movement(2) In the1994-2012years, the gravity center of population and GDP, the degree of deviation from the secondary and tertiary industries the focus of the first exhibit significantly enhanced the trend began to weaken after2004, described this phenomenon in Shanxi economic and demographic already started toward the direction of balanced development. The first industrial center of gravity shifted from the center of gravity relative to the population showed no obvious regularity, spatial distribution is more complex. Indicating there is still a large imbalance between the two.(3) Through the sensitivity analysis of population change between the two periods of Shanxi Province Economic and Industry, according to the sensitivity score can be divided into four major economic zone in Shanxi Province, and with the actual situation of economic development of Shanxi Province to match.
