摘要
选取中国2002-2013年省级面板数据,考虑地区R&D投入和FDI流入两种方式影响,采用非线性面板门槛回归模型,创新性将知识产权保护的非线性门槛性质引入模型,探讨地区R&D投入和FDI流入与国内研发创新能力的内在关系与作用机理。研究表明:地区R&D投入对创新能力的影响不仅仅限于简单线性关系或U型及倒U型框架,而存在着以知识产权保护强度为三重门槛的复杂非线性显著特征;其次,地区FDI流入对创新能力的影响仍受限于地区知识产权保护强度,随着知识产权保护强度的加大,FDI流入反而对创新能力的影响程度逐次减小,呈现出明显的门槛效应特征。总体上,门槛效应地区异质性明显,尤其应将较多R&D投入地区知识产权保护水平提升,而较多FDI流入地区知识产权保护水平抑制。
Drawing upon the 2002-2013 Panel Data at the province-level in China and considering the influence of R＆D input and FDI inflows, this paper uses nonlinear panel threshold regression to introduce the nonlinear threshold nature of intellectual property protection into the model and explores the mechanism between regional R＆D input and FDI inflows and the domestic innovation capability. The research shows that the impact of regional R＆D input on innovation capability is not limited to simple linear relationship or U-shaped and inverted U-shaped framework, but also have the complex nonlinear feature of the three thresholds of intellectual property protection; Sec- ondly, the impact of regional FDI inflows on innovation capability is still limited by the regional intellectual property protection： as the intensity of intellectual property protection increases, the impact of FDI inflows on the innovation ability gradually weakens, reflecting a typical threshold effect. On the whole, the threshold effect of regional heterogeneity is obvious, so efforts should be made to enhance the IPR protection in the R＆D-intensive areas and suppress the IPR protection in the areas targeted by FDIs.
