北京市银行业科技金融业务支持科技创新的研究——基于TVP-VAR模型的实证检验

Study on Science and Technology Financial Business Supporting Scientific and Technological Innovation in Beijing Banking Industry: An Empirical Test Based on TVP-VAR Model

科技与金融是我国发展自主创新道路的"双轮驱动"因素,厘清科技金融对科技创新的影响机制至关重要。在梳理北京市银行业科技金融业务与科技创新发展现状的基础上,采用TVP-VAR模型,从动态的角度研究科技金融与科技创新之间的联动关系。研究结果表明:两者之间存在非对称性特征,科技金融对科技创新的促进作用存在长期滞后效应;同时,科技金融对科技创新存在短期显著正向响应,但是在长期中出现明显的抑制作用。故而,在经济发展新常态时期,北京市政府应积极推进科技金融发展,通过提高金融效率助力科技成果资本化,进而驱动科技创新的持续稳定增长。

Science, technology and finance are the "two-wheel driving" factors in the development of independent innovation in China, so it is very important to clarify the influence mechanism of science and technology finance on science and technology innovation. On the basis of combing the present situation of science and technology finance business and science and technology innovation in Beijing banking industry, this paper adopts TVP-VAR model to study the linkage relationship between science and technology finance and science and technology innovation from a dynamic point of view. The results show that there are asymmetric characteristics between the two, and the longterm lag effect of science and technology finance on science and technology innovation;at the same time, the science and technology finance has a short-term positive response to the innovation of science and technology, but has obvious inhibition in the long-term. Therefore, in the new normal period of economic development, the Beijing Municipal Government should actively promote the development of science and technology finance, and promote the capitalization of scientific and technological achievements by improving financial efficiency, so as to drive the sustained and stable growth of scientific and technological innovation.
