摘要: 要素市场的扭曲弱化甚至也影响了政府补贴对企业创新的激励效应,为更准确反映这两个因素的作用程度及综合效应,本文以我国制造业2009-2016年A股上市公司为研究样本,在双边随机边界模型统一框架下测度和验证政府补贴、要素市场扭曲对企业创新的影响。研究发现:平均而言,政府补贴对企业创新的驱动效应并未完全冲抵要素市场扭曲对企业创新的抑制效应,二者的综合效应最终导致企业实际创新低于有效创新7.91%;通过产权异质性、地区差异和不同生命周期视角的考察,发现政府补贴和要素市场扭曲的综合效应使得企业实际创新低于有效创新这一状况并未随着企业特征分组而明显改善。因此,应优化创新生态系统,建立更加完善的政府补贴机制,完善要素市场,充分发挥要素市场对企业创新的驱动效应。

Abstract: Factor market distortion weakens and even distorts the incentive effect of government subsidies on enterprise innovation. In order to more accurately reflect the degree and comprehensive effect of these two factors, this paper measures and verifies the impact of government subsidies and factor market distortion on enterprise innovation under the unified framework of two-tier stochastic frontier model by taking A-share listed companies in China′s manufacturing industry in 2009-2016 as research sample.The results show that, on average, the driving effect of government subsidies on enterprise innovation does not fully offset the restraining effect of market distortion on enterprise innovation, and the combined effect of the two results in that the actual innovation of enterprises is 7.91% lower than the effective innovation;through the study of property heterogeneity, regional differences and different life cycle perspectives, it is found that the comprehensive effects of government subsidies and factor market distortion make the actual innovation of enterprises lower than effective innovation, which has not improved significantly with the grouping of enterprise characteristics.Therefore, we should optimize the innovation ecosystem, establish a more perfect government subsidy mechanism, improve the factor market, and give full play to the driving effect of factor market on enterprise innovation.
