摘要：    研发补贴作为政府弥补市场失灵、干预创新资本配置的重要手段，其有效性一直存在巨大争议。本文从研发补贴的效应出发，基于2011—2021年省际面板数据，利用门槛回归模型，识别适宜采用研发补贴的最优规模，并检验知识产权保护能否作为研发补贴“去”创新资本错配效应的“放大器”。实证结果显示：（1）研发补贴缓解创新资本错配的作用效果呈阶梯式递减，一旦补贴超过某一阈限，其缓解作用大大削弱甚至失灵；但当前60%以上省份尚未达到下行拐点，研发补贴仍可作为我国现行有效的创新干预策略。（2）研发补贴缓解创新资本错配的作用效果在创新资本配置不足地区更为显著。（3）加强知识产权保护有利于扩大研发补贴缓解创新资本错配的作用效果，且这种纠错效应在东部地区更为明显。本研究为更好发挥政府研发补贴作用、优化创新要素配置提供理论依据和实践指导。

Abstract:     The government R&D subsidy is commonly adopted to intervene and optimize the allocation of innovation capital. However, the effectiveness of R&D subsidies has been hugely controversial. Based on China′s inter-provincial panel data from 2011 to 2021, this study used threshold regression models to find the optimal scale of R&D subsidies and examined whether intellectual property protection can enhance the role of R&D subsidies in alleviating innovation capital misallocation. The findings are as follows: (1) The effect of R&D subsidies on alleviating the misallocation of innovation capital is marginal diminishing. Once R&D subsidies exceed a certain threshold, the alleviating effect will be greatly weakened or even fail. However, more than 60 percent of provincial-level regions have not yet reached this threshold. Therefore, R&D subsidies can still be used as an effective innovation intervention strategy in China. (2) The effect of R&D subsidies in alleviating the misallocation of innovation capital is more significant in areas with insufficient allocation of innovation capital. (3) Strengthening intellectual property protection is conducive to enhancing the effect of R&D subsidies on alleviating innovation capital misallocation, and this effect is greater in the eastern region. This study will provide a theoretical basis and practical guidance for better playing the role of R&D subsidies and optimizing the allocation of innovation factors.
