中国对外直接投资逆向驱动创新效率提升的检验——基于知识产权保护约束的视角

摘要

This paper uses the method of threshold regression, examines the regional innovation efficiency promoted by OFDI with IPR regulation.The results indicate that OFDI promotes the national innovation efficiency obviously in China, and there is a significant triple-threshold effect during the procedure of IPR regulation, showing the nonlinear character of the "N" figure, and the innovation efficiency promoted by OFDI is optimal in the appropriate IPR level, while there is also the IPR level of inhibiting innovation efficiency.Further studies indicate that, with IPR regulation, the innovation efficiency promoted by OFDI reveals spatial heterogeneity in China, showing different threshold characters, namely marginal increasing in the east, the"N" figure in the middle, the inverted "U" figure in the west, the inverted "U" figure in non "the Belt and Road" regions, and the"N" figure in "the Belt and Road" regions.Finally, reference and inspiration for implementing dynamic and differential IPR strategies are provided to drive innovation efficiency promotion by OFDI in the new era.%本文基于知识产权保护约束的视角,借助门槛回归方法检验对外直接投资对区域创新效率的驱动影响.结果显示:中国对外直接投资有效驱动了区域创新效率提升,同时这种驱动存在显著的知识产权保护三重门槛影响,具有"N"型非线性特征,在适度的知识产权保护强度下,对外直接投资对创新效率驱动最佳,但也存在不利于创新效率提升的知识产权保护瓶颈区.进一步研究发现,知识产权保护影响下,中国对外直接投资对区域创新效率驱动存在显著的空间异质性:在东、中、西部区域分别体现了边际递增、"N"型和倒"U"型的门槛特征,而在非"一带一路"地区和"一带一路"地区则显示了倒"U"型和"N"型的门槛特征.本研究为新时代中国实施动态差异化的知识产权保护策略,借助对外直接投资有效驱动区域创新效率提升,提供参考启示.
