能源富集区内部经济发展时空演进格局特征——以陕西省榆林市为例

Internal Temporal-Spatial Structure Characteristics and Regional Economic Development in a Resource-Rich Area

能源富集区是我国重要的功能类型区之一,为我国城市化、工业化快速推进提供能源动力基础。运用地理学、区域经济学等理论,借助空间自相关分析、GIS空间分析等研究技术,对榆林市12县(区)经济发展的时空演进格局进行了深入分析。结果表明:1990-2011年榆林市Moran’s I值总体呈现波动态势,1998年达最大值0.517 8,2007年跌入最低谷0.120 0;LISA集聚结果显示,1990年、1998年神木县为H-H类型区,而2007年、2011年H-H类型区未能再现,表明北6县经济发展后期呈现随机状态;1990年榆林市没有L-L集聚区,2011年绥德、子洲、清涧、吴堡4县形成南部经济贫困的L-L集聚区。区域经济发展动力机制分析表明,工业化对榆林市经济发展影响作用最大。农民人均纯收入对区域经济发展的影响由较低正向显著向较高正向显著转变。随着资源开发推进,由资源采掘业为主的单一产业带来的地方财政收入对区域经济的贡献减弱。

Resource-rich developing regions face the challenge of transforming resource wealth into other assets that support sustainable development while maintaining mechanisms to avoid boom-bust cycles that stem from volatility in natural resource revenue. Using the theory of geography and regional economy,spatial autocorrelation methods and spatial analysis,we studied temporal-spatial structural characteristics of regional economic development in Yulin City,Province,China. The results show that the Global Moran's I of economic development fluctuated from 1990 to 2011: the biggest value(0.517 8)appeared in 1998,and then the value of Global Moran's I gradually decreased until its smallest value(0.1200)in 2007. The LISA findings for global spatial agglomeration of economic development in Yulin were the existence of a positive effect. The diversity between H-H spatial agglomeration of economic development and L-L ones in Yulin showed significant imbalance,and changes showed that this imbalance had an extended trend between and within northern and southern regions from 1990 to 2011. H-H spatial agglomeration of economic development was identified in Shenmu in 1990 and 1998;L-L ones were economic poverty regions located in Suide,Zizhou,Qingjian and Wubao in 2011. The results of dynamic mechanism analysis of regional economic development showed that industrialization is a key role in social and economic change in resource-rich developing regions. Net household per capita income brings an effect from insignificant to significant and positive: per capita net income rose dramatically from 371 CNY in 1990 to 7230 CNY in 2011,but income inequality increased. Due to weakening construction of the resources industry,the effects of local financial revenue on economic development also weakened.
