FDI与丝绸之路经济带创新能力提升——基于基础设施投资的空间异质性调节作用

FDI and Improvement of Innovation Ability in Silk Road Economic Belt:Based on Spatial Heterogeneity Adjustment of Infrastructure Investment

本文作者基于2004~2015年丝绸之路经济带省际面板数据,采用DEA视窗分析法和空间杜宾模型,从创新空间关联视角考察了FDI对丝绸之路经济带中国沿线地区创新能力的影响以及不同类型基础设施在其中发挥的作用,并运用面板平滑转换模型对基础设施投资发挥"杠杆作用"的最优资金配置结构进行了识别。结果表明:当前丝绸之路经济带中国沿线地区创新活动存在"以邻为壑"的现象,本地创新会抑制创新关联地区的创新活动,FDI能有效提高丝绸之路经济带中国沿线地区创新能力;一般性基础设施投资和科技型基础设施投资均有利于FDI发挥创新效应,但其作用大小有别;在FDI提升丝绸之路经济带创新能力过程中,基础设施发挥"杠杆作用"的前提是科技型基础设施投资的占比达到0.171,丝绸之路经济带中国沿线地区基础设施投资的重点应逐步转向科技型基础设施。

Based on the panel data of Chinese provinces along the Silk Road Economic Belt during 2004 to 2015, using the DEA window analysis method and Spatial Durbin model, this paper investigated the influence of FDI on regional innovation ability and the role of different types of infrastructure from the perspective of innovation spatial correlation, and identified the optimal allocation structure of ＂leverage＂ in infrastructure investment through using the panel smooth transition regression model. The results are as follows. At present, there are ＂beggar-thy-neighbor＂ phenomena in the innovation activities in Chinese provinces along the Silk Road Economic Belt, and local innovation will restrain the innovation activities in the related areas, and FDI can effectively improve the innovation ability of Chinese provinces along the Silk Road Economic Belt. The general infrastructure investment and the science and technology infrastructure investment are favorable to the innovation effect of FDI. In the process of FDI improving the innovation ability, the prerequisite that the infrastructure plays ＂leverage＂ is that the proportion of the investment of science and technology infrastructure is up to 0.171, and the emphasis of the infrastructure investment in Chinese provinces along the Silk Road Economic Belt should be gradually shifted to the science and technology infrastructure.
