一小时经济圈尺度的中心城市与腹地关系测度研究——以东北地区四大核心城市都市圈为例

Measure Research of Center City and Hinterland Relationship on Scale of One Hour Economic Circle —— Taking Four Core City Metropolitan Area of Northeast China as an Example

以东北地区四大核心城市一小时经济圈为对象,利用城市流强度和经济联系隶属度模型测度中心城市与腹地关系。结果显示,沈阳一小时经济圈显现出空间极化—扩散的发展过程,中心城市与紧密腹地高度极化,一体化趋势明显;大连、哈尔滨一小时经济圈内中心城市仍然以空间极化为主,对腹地发展仍然具有剥夺作用;长春以空间极化为主,部分具有技术外部性的行业呈现选择性扩散,中心城市对腹地"借用规模"经济效应显现。

Taking the northeast four core cities＇ one hour economic circle as the object, through the using of city flow intensity model and eco- nomic links membership model, this paper studied on the relationship between the central city and hinterland. The authors found that one hour economic circle of Shenyang was now in the process from spatial polarization to diffusion, the center city and close hinterland highly polarized, had an obvious integration tendency. Dalian, Harbin one hour economic circle center city was still in the spatial polarization, and had the deprivation effect on hinter- land development. Changchun to spatial polarization, partly had technical externalities industry that showed a selective diffusion in space, the ＂bor- rowed size＂ economic effect on center city and hinterland appeared.
