摘要:為加快粵港澳大灣區區域一體化進程,基于“流空間”視角,以粵港澳大灣區11個核心城市為研究對象,從客運流、經濟流、信息流三個維度建立數理統計模型,分析粵港澳大灣區的交通、物流和經濟信息化水平,并綜合運用Jenks自然斷裂點法和Moran散點圖對粵港澳大灣區進行空間布局分級特征研究。研究結果表明:粵港澳大灣區有兩個增長極——廣州和深圳;粵港澳大灣區以珠江為界,珠江東西兩岸分級明顯;港珠澳大橋的連通有助于加強流要素空間互動,發揮更強的區域輻射和帶動作用,擴大H-H連綿區的分布范圍。
關鍵詞: 粵港澳大灣區; 流空間; 空間分級

Abstract: In order to speed up the process of regional integration of Guangdong-Hong Kong-Macao Greater Bay Area (GBA in short), based on the ‘space of flows perspective, 11 core cities of GBA are taken as the research object, and a mathematical and statistical model is established from three dimensions of passenger flow, economic flow and information flow. The traffic, logistics and economic information level of GBA are analyzed. The Jenks natural break point method and the Moran scatter point map are comprehensively used to study the spatial distribution and classification characteristics of GBA. Research results indicate that: there are two growth poles named Guangzhou and Shenzhen in GBA; GBA is bounded by the Pearl River, and the east and west sides of the Pearl River are clearly classified; the connection of Hong Kong-Zhuhai-Macao Bridge helps to strengthen the spatial interaction of flow elements, play a stronger role in regional radiation and driving, and expand the distribution of H-H contiguous area.
Key words: Guangdong-Hong Kong-Macao Greater Bay Area; space of flow; spatial distribution and classification

經濟社會發展推動著區域之間交流活動日趨頻繁,各種要素在空間上的流動問題已經成為研究空間格局、網絡結構的重要對象。值得注意的是,“流空間”理論強調的是研究視角由“屬性”向“關系”的轉變,流要素的具體研究內容主要體現在關系流對城市群、經濟圈等特定空間地域的相互作用,具有鮮明的網絡化結構特征,這也是流要素研究普遍的落腳點和出發點。
在社會學界和地理學界,“流空間”理論闡釋的是信息化社會的網絡空間,學者們嘗試借助空間相互作用模型[1],并結合實測關系數據綜合探討“流空間”及其網絡結構問題。研究內容包含交通流[2]、商貿流[3]、信息流[4]、文化流[5]、經濟流[6]等,旨在揭示區域各城市的空間聯系變化及其網絡流量差異?!?br>
