基于引力模型的城市群经济空间联系研究——珠三角城市群的实证研究

城市群经济空间联系的强弱直接影响城市群竞争力的强弱,进而影响一国的国家竞争力和国际地位。因此,为了提高我国城市群在国际竞争中的地位,加强城市群经济空间联系强度就显得非常重要。珠三角城市群作为我国经济最发达,最有活力的城市群之一,研究其经济联系强度不仅有助于继续发挥其对全国经济的辐射带动作用,而且对其他城市群的发展具有一定的借鉴意义。通过应用引力模型对珠三角城市群的分析得出,无论从GDP考察还是从人口考察,珠三角城市群经济空间联系逐步加强,并且充分体现出广州的中心城市地位,但深圳作为另一个中心城市的作用还有待加强。

Gravity Model Based on Spatial Connection of Urban Agglomeration Economies:An Empirical Study of the Pearl River Delta City Group

The economic space of linked cities directly affects the strength of urban competitiveness,thereby affecting a country’s national competitiveness and international status.Therefore,it is very important to strengthen the intensity of urban agglomeration economic space linked in order to improve our urban agglomeration position in international competition.Pearl River Delta(PRD) acts as one of China’s most economically developed and dynamic urban agglomeration.The study of the strength of economic ties of its cities will help to keep its leading role in the national economy,and it can serve as reference for the development of other urban groups.Through the application of gravity model analysis of the PRD draw,investigated in terms of GDP,or from the population study,it shows that the economic space contacts of the PRD city group are gradually being strengthened,giving full expression to the center of Guangzhou city,but the city of Shenzhen as the role of another center needs to be strengthened.
