珠江三角洲经济区中心城市经济辐射能力研究
通过研究广州、深圳等9个城市的经济指标，对珠江三角洲经济区中心城市经济辐射的能力进行评估，利用选取的城市综合评价指标，通过主成分分析、经济关联强度分析，得出深圳、广州、佛山为三个主要的经济辐射城市，它们的经济辐射半径分别为：190.4245公里、179.3416公里和135.0916公里。并通过修正引力模型为经济模型，量化分析了中心城市对周围经济和金融的辐射带动作用，得出广州市作为辐射半径最大的城市，其与佛山的关联强度高达2287.124，充分说明了现今广佛同城的现象。并用金融可达性的分析，对偏远地区金融可达性不足的原因提出了适度的建议。

Abstract
The economic radiation, simply to understand is that the efforts to driven development of the around cities.
Over the years, The city is the center regional carrier of the country's , Its essence is that in a certain space, various industries are interdependent and mutually reinforcing economic output.In current society, compared with the general role of cities, urban leading role in regional economic development is more prominent, more and more attention by.
This article attempts through the research of guangzhou, shenzhen and other seven cities’s economic indicators, access the radiation ability to the pearl river delta economic zone central city. At the last,we know that the economic radiation radius of the three cities were 190.4245 kilometers, 179.3416 kilometers and 135.0916 kilometers. Through principal component analysis, economic strength analysis, and come to result that shenzhen, guangzhou, foshan are three main economic radiation. Through the modified gravity model for economic model, we haved quantitative analysis the central city on the surrounding the radiating and driving play of economic and financial, and the city of the causes of deficiency of financial accessibility good suggestions were put forward.

珠江三角洲经济区中心城市经济辐射能力研究
一、问题重述
1.1问题背景
经济辐射是指在现代化程度高、社会经济发展快速的地区向相对落后的地区进行资金、人力、科技等社会要素的流动转移及思想、思维、生活习性等生活方式的流动传播。通过这些传播和流动，能够促使社会经济资源在城市之间的进一步重新转移、流动，从而促使社会达到资源配置的最佳状态。
