Study of Economic Space Development Evolution Features of ESDA Technique in JingJinji Metropolis Circle

Abstract

ESDA technique in spatial econometrics is utilized for analyzing pattern and evolution of economic and special structure in JingJinji area from 1995 to 2012. Non-agricultural population during the time period is counted; rank scale rule, ROXY index, urban influence and other quantitative methods are applied to systematically studying evolution of scale structure and special structure in urban system in JingJinji Metropolis Circle. Spatial polarization indicators are utilized for estimating space polarization change trend on JingJinji Metropolis Circle during the time period. On the basis, two-dimensional and three-dimensional space expression modes of GIS space analysis technique are adopted for special simulation of economic polarization growth in JingJinji Metropolis Circle in recent 15 years, thereby analyzing special polarization process in JingJinji Metropolis Circle from two dimensions of time and space. The results showed that: 1. JingJinji Metropolis Circle is in dispersed development trend, overall trend of economic space difference is continuously expanded, economic growth polarization of Metropolis Circle is increased with time, economic growth of Metropolis Circle due to change trend of economic center to external space, and it does not completely follow distance attenuation rule.
