粤港澳大湾区基本公共服务与经济发展耦合协调的时空特征

基本公共服务与经济耦合协调度发展是包容性增长的重要内容。论文运用熵值法、耦合协调度模型和核密度估计方法，研究粤港澳大湾区2009—2019年基本公共服务与经济发展耦合协调的时空特征。结果表明：(1)基本公共服务与经济发展综合水平均呈现波动上升趋势，但具有明显的阶段性特征，且二者发展不完全同步。(2)基本公共服务与经济发展耦合作用强，协调性逐渐改善，但耦合协调等级没有发生跃迁，始终为勉强耦合协调类型，形成外围低中心高的空间格局。(3) 11个城市耦合协调亚类型异质性明显，外围的江门、惠州、肇庆均属于经济发展滞后型。分区域看，经济发展滞后型主要分布在研究区西部(澳珠中江)，基本公共服务滞后型主要集中在研究区东部(深港莞惠)和中部(广佛肇)。(4)低值区耦合协调度呈上升趋势，高值区城市之间的差异性在逐渐缩小，高值区与低值区城市间形成了两极分化现象。该成果能为相关部门在制定粤港澳大湾区经济与基本公共服务建设协调政策时提供理论依据。

Spatio-temporal characteristics of the coupling and coordination of Guangdong-Hong Kong-Macau Greater Bay Area’s basic public services and economic development

Coordinated development of basic public services and the economy is an important part of inclusive growth. Based on entropy method, coupled coordination degree model and Kernel density estimation method, this paper studies the spatio-temporal characteristics of coupling coordination between basic public services and economic development in the Guangdong-Hong Kong-Macao Greater Bay Area from 2009 to 2019. The results show that: 1) The comprehensive level of basic public services and economic development shows an upward trend of fluctuation, but with obvious stage characteristics, and the development of the two is not completely synchronous. 2) Basic public services and economic development have a strong coupling effect, and their coordination is gradually improved. However, there is no transition in the level of coupling coordination, which is always a kind of forced coupling coordination, forming a spatial pattern of low peripheral and high center. 3) The oupling coordination subtype heterogeneity of 11 cities is obvious, and the peripheral Jiangmen, Huizhou and Zhaoqing all belong to the lagging type of economic development. From a regional point of view, the lag of economic development is mainly distributed in the West, while the lag of basic public services is mainly concentrated in the East and the Middle. 4) The coupling coordination degree of the low value area shows an upward trend, the difference between the cities in the high value area is gradually narrowing, and the polarization phenomenon is formed between the cities in the high value area and the low value area. The results can provide a theoretical basis for relevant departments to coordinate policies for economic and basic public services in the Guangdong-Hong Kong-Macao Greater Bay Area.
