中国区域间技术创新的空间溢出效应研究

Spatial Spillover Effect Analysis of Inter-regional Technology Innovation in China

本文结合新经济地理学K关联的思想构造了外部技术创新溢出指数模型,在此基础上运用2006~2014年中国30个省级行政区的面板数据对中国区域间技术创新空间溢出效应进行了实证研究,结果表明:(1)全国技术创新溢出效应主要是东部地区带动的,东部地区的省份对东部、中部和西部地区其他省份存在技术创新溢出效应,而中部和西部并没有对其他地区技术创新产生溢出效应,并且中部地区和西部地区内部各省之间存在竞争效应。(2)无论是全国还是东部、中部和西部地区,R&D经费、R&D人员和知识存量均对技术创新产生正向作用,并且这些地区的技术创新产出均处于规模报酬递减阶段,不同的是,全国、东部和中部地区R&D人员对技术创新的贡献比R&D资本要大,而西部地区R&D资本对技术创新的贡献则要大于R&D人员。

This paper sets up an external overflow index model of technological innovation based on spatial geographic distance, and conducts a decomposition research on the spillover effect of China’s regional technology innovation, using the panel data of30 provinces from2006 to2014. The results indicate that:(1)National technology innovation spillover effect is mainly led by the east of China, which means that the provinces in the east have spillover effects of technological innovation on the other provinces in the eastern, central and western areas;however, the central and western ones have no spillover effects of technology innovation on other areas;there is also a competition effect between central and western regions.(2)As for the whole China and the eastern, central or western regions, R&D funds, R&D personnel and knowledge stocks show positive effects on technological innovation;technology innovation outputs are at the decreasing stage of the scale return, whose difference is that R&D personnel of eastern and central regions make greater contribution to the technology innovation than R&D funds, while the R&D funds of western provinces make greater contribution to the technology innovation than the R&D personnel.
