京津冀城市群设计产业与城市发展耦合协调关系研究

Study on the Coupling and Coordination Relationship Between the Design Industry and Urban Development in the Beijing-Tianjin-Hebei Urban Agglomeration

文章通过熵值法和耦合协调度模型等方法,对京津冀城市群2011—2020年设计产业与城市发展耦合协调的时空分异特征进行研究。结果表明:(1)设计产业与城市发展综合水平阶段性特征显著,设计产业呈波动上升而城市发展水平呈波动下降的发展趋势。(2)设计产业与城市发展耦合作用在2011—2020年间有所减弱,协调性由0.379下降为0.369,始终为一般失调类型,呈现中间高边缘低的空间格局。(3)13个城市耦合协调亚类型相关性与差异性并存,外围城市多为城市化滞后型,设计产业滞后型多分布在北京;耦合协调度高值区和低值区两极分化现象严重。高值区域的城市等级差距逐渐加大,低值区域的城市等级差距各异,但是总体差距呈现逐渐缩小的态势。研究结论可以为政府相关部门在制定设计产业和城市发展协调政策时提供理论依据。

This paper investigates the spatial and temporal differentiation characteristics of the coupling and coordination between the design industry and urban development in the Beijing-Tianjin-Hebei urban agglomeration from 2011 to 2020,using methods such as the entropy value method and the coupling coordination degree model.The results show the following:(1)The comprehensive levels of the design industry and urban development exhibit notable phase characteristics, with the design industry showing a fluctuating upward trend while urban development shows a fluctuating downward trend.(2)The coupling effect between the design industry and urban development weakened during the 2011-2020 period,with the coordination degree decreasing from 0.379 to 0.369,remaining in the range of general imbalance. The spatial pattern shows a high centrality with low peripheral values.(3)There is a coexistence of correlations and differences among the subtypes of coupling coordination in the 13 cities,with peripheral cities often being categorized as urbanization lagging types,while design industry lagging types are mainly distributed in Beijing.Severe polarization is observed between the high-value and low-value regions in terms of coupling coordination degrees.The disparity in urban rankings is widening in high-value areas,while in low-value areas, the gaps vary but show an overall trend of narrowing.The conclusions of this study provide a theoretical basis for government agencies when formulating policies to coordinate the development of the design industry and urban growth.
