东北地区产业结构优化与城市土地集约利用协调性

精准识别产业结构优化与城市土地集约利用的协调状况,对于推动东北地区产业结构转型升级、协调国土空间规划及产业布局具有重要现实意义。运用耦合协调度模型及探索性空间数据分析法,深入探究了2009—2018年东北地区产业结构优化与城市土地集约利用的耦合协调水平及其空间相关性。结果表明：（1）东北地区城市产业结构合理化水平逐年降低,且区域差异程度较大;产业结构高级化水平小幅上升,但不存在明显的空间分异特征。（2）城市土地集约利用水平呈现出先上升后下降的倒“U”型演变特征,并沿着哈大交通经济带的中心城市向两侧梯度递减。（3）产业结构合理化、产业结构高级化与城市土地集约利用协调度分别呈现先上升后下降及稳步上升的演变态势。两协调度均以大连、哈尔滨等城市为中心向外辐射,呈现“多中心多圈层”的空间分布特征。（4）城市两系统协调度存在显著的空间正相关,但显著性逐年减弱,其中高—高聚集类型主要集中在辽中南城市群,低—低聚集类型集中在黑龙江东部城市群。

Study on the coordination between industrial structure optimization and urban land use intensity in Northeast China

Accurate identification of the coordination between industrial structure optimization and urban land use intensity has important theoretical value and practical significance for promoting the transformation and upgrading of industrial structure, coordinating land space planning and industrial layout, as well as achieving a new round of high-quality revitalization in Northeast China. This paper uses Theil index, Moore structure change index, entropy weight method plus the coupling coordination degree model and exploratory spatial data analysis method to explore the coupling coordination level and spatial correlation between industrial structure optimization and urban land use intensity in the study area from 2009 to 2018. The results show that: (1) The rationalization level of urban industrial structure is decreasing year by year, with a large regional gap, which is reflected in the high level of central cities and low level of surrounding cities. The upgrading level of industrial structure rose slightly, with no obvious spatial differentiation. (2) The level of urban land use intensity shows an inverted "U" shape, which first increases and then decreases, and finally decreases along the central cities of Harbin-Dalian Transportation Economic Belt. (3) The coordination degree of industrial structure rationalization and urban land use intensity first increased and then decreased. The coordination degree of industrial structure upgrading and urban land use intensity gradually increases with time. The two coordination dispatching centers of Dalian and Harbin present a spatial distribution of "multi-center and multi-circle pattern". (4) There is a positive spatial correlation between the industrial structure optimization and the coupling coordination degree of urban land use intensity, but the significance is weakening year by year. The H-H aggregation areas concentrated in the Central-south Liaoning urban agglomeration, while L-L aggregation areas concentrated in the Eastern Heilongjiang urban agglomeration. In order to improve the coordination of industrial structure optimization and urban land use intensity, based on the empirical results and the actual development, two policy suggestions are put forward in this paper. One is giving full play to the advantages of central cities such as Shenyang, Dalian, Changchun and Harbin, so as to drive the surrounding cities to realize the coordinated development of industrial structure optimization and urban land use intensity; the other is coordinating the allocation of industries according to local conditions and forming the connotation intensive industrial development trend on the basis of urban land intensive use.
