Spatial analysis of urban economics in Guangdong Province

Abstract

利用空間分析方法,在ArcGIS以及GeoDa的支持下,從時空變化的角度,對廣東省2002—2012年城鎮化發展以及城鎮化過程中的經濟結構和空間布局發展變化進行了分析。結果表明:到2012年,廣東省各個城市的城鎮化已經全部進入城鎮化加速發展階段。廣東省的經濟發展與城鎮化發展并不完全一致,城鎮化發展水平以及經濟發展水平在空間布局上有較大的異質性,經濟發展程度較高的城市都集中在東莞以及周邊地區,而城鎮化發展程度較高的城市集中在珠三角偏東北部的沿海城市。同時,第一產業對城鎮經濟發展影響較小,第二、第三產業作用較大,不同的產業構成也有各自的空間布局特點以及空間布局變化特征。第一產業空間分布在近10年均衡性變弱,東部比重減少較快;第二產業趨于沿海分布,差異性減弱,空間分布均衡性提高;第三產業差異緩慢增大,空間分布較為均衡。通過分析,從而掌握廣東省城鎮化發展過程中經濟發展狀況的空間布局以及時空變化特點,對政府決策提供參考。 In this paper, from the perspective of temporal and spatial variation of Guangdong Province, spatial analysis methods, as well as spatial analysis software such as ArcGIS and Geoda are applied in the proposed studies. ]he purpose of the studies are to investigate changes of spatial distributions and structures of urban economics in Guangdong province from 2002 to 2012. q-he results showed that：until 2012 ,the cities in Guangdong Province have all entered the accelerated stage of urbanization development. However, spatial distribution of urban economics is a little different from spatial distri- bution of urbanization development in Guangdong Province. Cities with highly urban economic development are distributed in Dongguan and its surrounding areas while cities with highly development of urbanization are distributed in the coastal areas of east-north part of the Pearl River Delta Areas. Moreover, the primary industry has a small influence on urban e- conomics while the secondary industry and the tertiary industry have large influences on urban economics. Spatial distribu- tions of different industries are also different from each other ,they all have their characteristics of spatial distribution：the inequalities of spatial distributions of the primary industry became obvious in the past decade ,cities with high ratio of the secondary industrial production are concentrated in the coastal areas, and the tertiary industry of Guangdong Province is in a more balance distribution and differences between cities are growing slowly. In short,it can be served as decisions mak- ing support of governments through analysis to explore the basic law of the spatial distribution and temporal changes of urban economics and urbanization development in Guangdong Province.
