Characteristics of Economic Growth in Guizhou and its Inspiration to PM2.5Control

Abstract

Guizhou province, one of the poorest provinces in China, has attracted the state's close attention. The work selected such data of GDP, per-capita GDP, and industrial structure from Guizhou Statistical Yearbook and Guiyang Statistical Yearbook from 1995 to 2019. Then the spatiotemporal characteristics of county region economy were studied using several methods including spatial autocorrelation (Moran's I), and standard deviation coefficients based on GIS. The results showed that Guiyang and Zunyi were the centers of economic growth in Guizhou. There was a regional differentiation that the growth of county GDP lowered from northwest to southeast. The industrial structure changed significantly in Guizhou's county level in 2005 and 2009, and ITI was 6.7 and 8.3, respectively. There was a noticeable tendency that developed counties had low ITI. In contrast, spatiotemporal characteristics of per-capita GDP growth were more complex, and these counties of high per-capita GDP disbursed over a wide region of the Guiyang- Zunyi industrial zone. Finally, we analyzed the enlightenment on PM2.5 control in Guizhou.
