| 摘 要： | 基于现有研究仅仅考察科技基础设施投入对技术创新单向影响这一缺陷，文章重点探讨了科技基础设施投入与技术创新之间的交互效应，首先在理论层面上对交互效应的作用机制进行深入分析，然后利用2009-2015年中国大陆30个省市的面板数据建立联立方程模型，用三阶段最小二乘法（3SLS）从实证层面上检验二者之间的交互效应，得到如下结论：（1）就全国层面而言，科技基础设施投入与技术创新之间呈现出相互促进的交互效应，科技基础设施投入表现出显著的技术创新效应，而技术创新同样有助于加大科技基础设施投入；（2）分地区来说，东部地区科技基础设施投入过量对技术创新的促进作用不再显著，而中西部地区依然表现出相互促进的交互效应，不同地区之间科技基础设施投入对技术创新的影响大小存在差异，具体表现为中部>西部>东部。

Interaction between technological infrastructure investment and technological innovation |
| |
| Abstract: | Based on the limitation of existing research on the one-way impact of technological infrastructure investment on technological innovation, this paper focuses on the interaction effect between the two. Firstly, it analyzes the mechanism of the interaction effect on the theoretical level and then uses the panel data of 30 provinces in China from 2009 to 2015 to establish the simultaneous equations model to test the effect, the conclusions are as follows:(1)At the national level, there is a mutually reinforcing interactive effect between technology infrastructure investment and technological innovation. Technology infrastructure investment contributes significantly to the increase in technological innovation. Increasing technological innovation also helps to increase large technology infrastructure investment.(2)In terms of sub-regions, the contribution of over-investment in technology infrastructure in the eastern region has no significant effect on technological innovation. However, the central and western regions still show a mutually reinforcing interactive effect. There are differences in the impact of technology infrastructure investment on technological innovation among different regions, which are manifested in Central> Western> Eastern. |
