摘要
以2000-2018年国内外期刊数据库合作论文数据为基础,借助社会网络分析和空间结构指数法分析了粤港澳大湾区知识空间网络结构演化特征与影响因素,结果发现:1)知识网络格局由广州的“一家独大”逐渐演变为广州、深圳、香港“齐头并进”的发展态势.香港虽然处于知识网络的核心位置,但受行政壁垒的影响,主要与广州、深圳高等级的城市建立紧密的知识合作联系.2)粤港澳大湾区知识联系网络呈现“核心—边缘”结构,西部地区知识联系远低于东部地区,虽然研究期内湾区的知识网络的极化特征得到一定的缓解,但不均衡性仍然显著.3)湾区知识活动主体的自身需求是促进城市间知识合作的内在驱动力,知识环境和知识联系通道是区域知识合作网络外在推动力,在内生作用和外生作用的共同影响下,知识合作产出得以实现,粤港澳大湾区知识网络得以发展.
Increasing globalization and informatization has enhanced the intercity exchange of information, materials, and energy. Cities no longer represent isolated systems. Instead, they are closely linked to each other, forming regional or global city network systems. Therefore, the study of urban networks has attracted massive attention in human geography and urban planning. In particular, the emergence of the concept of "space of flow" provides a new perspective and paradigm for the interpretation of regional spatial structure. Based on the data collected from domestic and foreign journal database published from 2000 to 2018, this paper uses social network analysis method and spatial structure index method to explore the evolution process of the overall characteristics, organizational structure, and the spatial pattern of the knowledge network in Guangdong-Hong Kong-Macao Greater Bay Area. Furthermore, it identified the evolution trend of factors influencing the knowledge network in the Bay Area. The results also revealed the following: 1) Over the duration of the research, publications in the Greater Bay Area significantly increased. The pattern of the knowledge network gradually evolved from the "single power" represented by Guangzhou to "simultaneous developmenf" that included Guangzhou, Shenzhen, and Hong Kong. Although Hong Kong is at the core of the knowledge network, it establishes close knowledge cooperation primarily with Guangzhou and Shenzhen due to administrative barriers. 2) The knowledge network of the Guangdong-Hong Kong-Macao Greater Bay Area represents a "corevdge" structure with the knowledge connection in the western region significantly lower than that in the eastern region. The knowledge network densities and spatial structure indices of the Guangdong-Hong Kong-Macao Greater Bay Area suggest an increasing volatility. In 2016, the knowledge network density of the Bay Area attained the maximum value, indicating the development and maturity of the overall knowledge connection of the Guangdong-Hong Kong-Macao Greater Bay Area. In addition, the spatial structure indices demonstrate an alleviation of polarization characteristics of knowledge networks in the Bay Area, despite persistent significant imbalance. 3) The demand of the knowledge activity actors such as universities and scientific research institutions in the Bay Area is the internal driving force promoting knowledge cooperation among cities. The knowledge environment and the knowledge connection channels are the external driving forces of the regional knowledge cooperation network. The influence of endogenous and exogenous factors is responsible for the output of knowledge cooperation, resulting in the development of the knowledge network in the Guangdong-Hong Kong-Macao Greater Bay Area. This study provides a reference for the development of innovative collaborative paths in the Guangdong-Hong Kong-Macao Greater Bay Area by refining the characteristics of Bay Area's knowledge network.
