城市群内城市分级方法比较研究--以成都平原城市群为例

Comparative study on city classification within urban agglomeration

以成都平原城市群为例,按照行政区划、城市人口规模并运用波士顿矩阵方法对城市群内部城市进行分级,对结果进行比较分析,得出的最终结论是:城市群内的成都市是明星城市,其他主要城市绵阳、德阳、眉山和资阳是瘦狗城市,没有现金牛城市,说明城市群整体实力不强;没有问题城市,等级出现断层,说明城市分级出现两极化趋势。研究结果表明,波士顿矩阵不仅考虑了双重指标,而且把绝对指标与相对指标相结合、静态指标与动态指标相结合,得出的分级结论更全面可靠,是城市群内部城市分级的一种值得借鉴的方法,可以作为城市群细化城市间关联性研究的起点。

Focused on the urban agglomeration of Chengdu Plain,this article classifies cities by regionalism,population size and the Theory of Boston Matrix. After comparing the results,it comes to the conclusion that in urban agglomeration of Chengdu Plain Chengdu is a Star City while Mianyang,Deyang,Meishan and Ziyang are Dogs Cities,and there are no Cash Cows Cities. All the evidence shows that the urban agglomeration of Chengdu Plain is discontinuous distribution. The classification by Boston Matrix uses double criterions, and even combines absolute criterion and relative criterion, static criterion and dynamic criterion, so it can be used as a current way of city classification and as a start point of the interior study of urban agglomeration.
