【摘要】：创业风险投资是京津冀城市群一体化协同创新进程中的重要驱动力。本文利用社会网络分析方法分析了京津冀城市群创业风险投资的时空分布特征,在此基础上利用引力模型和计量分析模型揭示京津冀城市群创业风险投资时空分布的影响机制。主要结论为:京津冀城市群的创业风险投资网络在总额方面具有一定的周期波动性,其时空分布的不均衡性缓慢降低,创业风险投资的三中心(北京、天津和唐山)对周边城市具有一定的带动作用;创业风险投资在城市间的流动呈现出一定的网络性,但是发育缓慢,具有很强的向心性;创业风险投资对创业项目不同阶段的投资从偏重创业后期逐步趋向各阶段均衡发展;信息基础设施发展水平和经济发展水平与创业风险投资之间具有较强的正相关作用;金融环境、服务业发展水平相对滞后,对创新创业成果的转化和资金吸引能力较弱。
[Abstract]:Venture capital is an important driving force in the process of Beijing-Tianjin-Hebei urban agglomeration. This paper analyzes the spatial and temporal distribution of venture capital in Beijing-Tianjin-Hebei urban agglomeration by using social network analysis method, and reveals the influence mechanism of the space-time distribution of venture capital in Beijing-Tianjin-Hebei urban agglomeration by using gravity model and econometric analysis model. The main conclusions are as follows: the venture capital network of Beijing-Tianjin-Hebei urban agglomeration has a certain period fluctuation in total amount, its spatial and temporal distribution unbalance decreases slowly, the three centers of venture capital (Beijing, Beijing, Tianjin and Tangshan) have a certain driving effect on the surrounding cities; the flow of venture capital between cities shows a certain network, but the development is slow, with a strong concentric; Venture capital has a strong positive correlation between the level of development of information infrastructure and the level of economic development and venture capital. In the financial environment, the development level of the service industry is relatively lagging behind, and the ability to transform and attract funds to the achievement of innovation and entrepreneurship is weak.
