摘要:

利用2007年和2017年创业投资事件数据和社会网络分析法构建中国地级及以上城市网络关系,分析种子期、初创期、扩张期和成熟期4个投资阶段创业投资城市网络的空间结构演变特征并对其影响因素进行计量分析。研究发现:4个阶段的创业投资城市网络均形成以三大城市群为核心联系区域的网络结构,并且均具有明显的高行政级别城市指向性;城市网络密度和中心化趋势均不断增强,且中后期阶段的紧密程度和协同化发展趋势领先于早期阶段;京沪深在4个阶段均演变为集聚力和辐射力前三甲城市;4个阶段的城市创业投资集聚力均呈现出向网络核心城市进一步集中的态势,而创业投资辐射力则呈现出显著的分异性;市场规模、创业企业发展基础和政府支持是影响创业投资城市网络空间结构演变的主要因素。

Abstract:

Based on the data of China's cross-city venture capital investment in 2007 and 2017, the network linkages between 338 cities at prefectural level and above were constructed. The spatial structure evolution of the venture capital city networks of the four investment stages of seed, start-up, expansion and maturity and its influencing factors are investigated by using the social network analysis model. Major findings are as follows: Firstly, the venture capital city networks of the four investment stages have formed a network structure with three major urban agglomerations as the core connection areas. Secondly, the density and centralization trend of the venture capital city networks of the four investment stages are constantly increasing, and the tightness and synergistic development trend of the venture capital city networks of the expansion stage and the maturity stage are ahead of the seed and start-up stage. Thirdly, Beijing, Shanghai and Shenzhen have all evolved into the top three cities in terms of concentration and radiation in the venture capital city networks of the four investment stages. What's more, the agglomeration level of venture capital investment of the four investment stages shows a trend of further concentration to the core cities of the network; The radiation level of venture capital investment of the core cities in the city networks of the seed stage shows significant differentiation with the other three stages. Lastly, the venture capital city networks of the four investment stages indicate significant high administrative level urban orientation. The market size, development foundation of startups and government support all have a significant impact on the spatial structure evolution of the venture capital city networks of the four investment stages. The financial development level, development foundation of the venture capital industry and urban accessibility only affect the spatial structure evolution of some investment stages.

Key words: venture capital, city network, investment stage, spatial structure
