中文摘要：
以2000年与2010年广东省人1：7普查为数据基础，对广东省域范围内县级以上空间单元进行位序规模、空间自相关、产业构成相对多样化与城市外向功能强度等量化分析，从空间结构与经济结构两个方面论述巨型城市极化效应在广东省域的影响。研究结果显示，人口的空间分布变化在一定程度上反映了广东区域非均衡发展趋势。从主要产业部类来看，各产业尤其是制造业的溢出一扩散效应较弱，公共服务业与生产性服务业出现了较为明显的集聚现象。珠三角的扩散效应缺失与极化效应凸显，进一步表现为城市外向功能强度与产业相对多样化水平以珠三角为中心表现出较强的递增趋势，同时粤北地区的劣势最为突出。在广东省域近期区域发展政策的基础上，结合粤北地区人口流动的调研访谈，研究提出重点依托珠三角南北向主轴向北辐射粤北地区，将区域外部问题内部化，实现广东省域中、东、西三片区域再平衡的城镇化战略。
英文摘要：
This research is based on national census data and uses tools of Rank-Size, Spatial Autocorrelation, Relative Diversity Index and Outward Urban Functions Strength to explore the polarization effect in Guangdong. The result shows unequal population growth in the province. The Overflow-Diffusion effect is relatively weak in each industry, while spatial agglomeration is significant in public service industry and advanced service industry. The result of weak Over- flow-Diffusion effect and significant polarization is indicative of strength of growth in the Pearl River Delta in comparison with Northern Guangdong. Based on ananalysis of a series of regional development policies in Guangdong and spa- tial economic structure, this paper proposes to integrate Northern Guangdong into the Pearl River Delta so that interregional conflicts could be minimized. As a re- sult, Guangdong would consists of three regions： Eastern Guangdong, Western Guangdong and the enlarged Pearl River Delta Region.
