“十五”时期环渤海城市群经济联系分析

Economic Contacts of Urban Groups in Bohai Sea Rim in the Tenth Five-Year Periond

环渤海城市群是中国北方重要的经济增长区域,未来发展前景十分广阔,分析"十五"时期环渤海城市群经济联系的动态变化规律必将为"十一五"乃至更长一段时期环渤海城市群空间经济联系产生"抛砖引玉"的功效。选取"十五"时期环渤海地区京津冀、辽中南、山东半岛共28座城市的市区从业人员、GDP、人均GDP等指标,利用城市流强度等模型测度了三大城市群内部经济联系强度,并与长三角、珠三角共25座城市相比较。结果表明:京津冀城市群经济联系强度居环渤海地区首位,辽中南次之,山东半岛位居最后;"十五"期末与期初相比,京津冀、辽中南的经济联系强度均呈上升态势,其中,尤以京津冀上升幅度最大,而山东半岛则出现了明显的下降;与长三角、珠三角相比,京津冀经济联系强度虽弱于长三角,但略强于珠三角,而辽中南、山东半岛与长三角、珠三角的差距则更为显著。

The urban groups in Bohai Sea Rim are important growing regions in North China and their dvelopment are very bright in the future. To promote the urban economic contacts in the future, it is necessary that their varying rules of the economic contacts in these days should be analyzed. Based on urban population, employees, GDP, per capital GDP, etc. of 28 cities in Beijing-Tianjin-Hebei metropolis, South-Central of Liaoning metropolis and Shandong peninsula metropolis in Bohai Sea Rim, the extrovert energy, the intensity of urban flow and the degree of tendency of three urban groups in Bohai Sea Rim are measured in the Tenth Five-Year Plan period. The 28 cities of three urban groups in Bohai Sea Rim are contrasted to 25 cities in two urban groups of Yangtze delta and Pearl River Delta in Southeast China. And the three urban groups in Bohai Sea Rim are contrasted to the two urban groups in Southeast China in the same. It is concluded from our studies that the economic contacts of Beijing-Tianjin-Hebei metropolis is the strongest in Bohai Sea Rim and South and Central Liaoning metropolis is the second and Shandong peninsula metropolis is the weakest. In the Tenth Five-Year Plan period, the economic contacts of Beijing-Tianjin-Hebei metropolis and South and Central Liaoning metropolis became stronger but Shandong peninsula metropolis became weaker in the end. The economic contact of Beijing-Tianjin-Hebei metropolis is weaker than Yangtze Delta metropolis but stronger than Pearl River Delta metropolis. South and Central Liaoning metropolis and Shandong peninsula metropolis are much weaker than Yangtze Delta metropolis and Pearl River Delta metropolis.
