新结构经济学视角下银行业结构对企业研究与实验发展投入的影响

目前,我国经济增长面临的减速压力,创新活动没有达到宏观经济需要的水平是经济增长乏力的内因,而RD投入不足又导致创新不足。为解析银行业结构对企业研究与实验发展(RD)投入的系统性影响方向和力度,论文以新结构经济学为基点,构建了信息不对称条件下不同科技贷款技术的利润模型,分析银行业结构与企业RD投入之间的因果关系,采用2002年—2017年间中国省级数据进行实证检验。结果表明:中小银行占比的提高,有利于各种规模企业RD项目融资;专利申请数量与中小银行占比之间存在正相关关系;关系型科技贷款技术的委托代理成本与银行规模正相关;促进银行业结构向中小银行倾斜是破解融资约束、提升我国各省企业RD投入的政策关键。

The Impact of Banking Structure on R&D Input from the Perspective of New Structural Economics

To analyze the systematic influence direction and dynamics of banking structure on enterprise R&D input, taking new structural economics as the base point, this paper constructs a profit model of different technology loan technology under asymmetric information, analyzes the causal relationship between banking structure and R&D input, and uses China''s provincial data from 2002 to 2017 to conduct empirical tests. Results show: if the proportion of small and medium banks is increased in the banking sector, that will be conducive to SME R&D project financing; there is a positive correlation between the number of patent applications and the proportion of small and medium-sized banks in the banking sector; there is a positive correlation between the principal agent cost and the bank size, that led to the adoption of this technology cannot achieve large-scale commercial banks. At last, by promoting the banking structure to small and medium banks tilt, we can crack the financing constraints of the enterprise independent R&D investment in China.
