风险投资、融资约束与研发投资周期性

根据机会成本理论,研发投资在理想情形下应呈逆周期性,但实证研究发现,由于融资摩擦的存在,研发投资呈顺周期性.风险投资对缓解研发资源融资约束方面具有显著作用,但其对被投资企业研发周期性的影响尚不清楚.本文从理论上和实证上探讨风险投资对融资约束与研发投资周期性的平滑作用机制,研究发现,风险投资能平滑研发投资的顺周期性;经营衰退期较繁荣期而言,风险投资对研发投资顺周期性的平滑作用更强;风险投资对研发投资顺周期性的平滑作用通过缓解融资约束实现,此时研发投资周期的不对称性仍然存在,风险投资对融资约束下研发投资顺周期性的平滑作用也在经营衰退期更强.本文的研究结果丰富了风险投资作用、研发投资周期性及其融资约束效应的相关理论和文献,对风险投资实践有一定的指导意义.
Venture Capital,Financial Constraints,and Cyclicality of R&D Investment
According to opportunity cost theory,R&D investment should ideally be countercyclical.However,empirical studies find that R&D investment is procyclical due to the presence of financing frictions.Venture capital has a significant role in alleviating R&D re-source financing constraints,but its effect on the R&D cyclicality of investee firms is unclear.This paper theoretically and empirically explores the smoothing mechanism of venture capital on financing constraints and R&D investment cyclicality.It is found that venture capital can smooth the procyclicality of R&D investment;the smoothing effect of venture capital on the procyclicality of R&D investment is stronger in the business recession period than in the business boom period.Further,it is found that the smoothing effect of venture capital on the procyclicality of R&D investment is achieved by alleviating the financing constraint,and the asymmetry of the R&D in-vestment cycle still exists at this time.Collectively,we contribute to the understanding of venture capital alleviates the financing con-straint effect of R&D investment by the evidence on the effect of cyclicality of R&D investment on opportunity cost theory.
