我国高技术产业技术创新效率影响因素及区域联动效应研究*

Research on Influencing Factors and Regional Links of Technical Innovation Efficiency of High-Tech Industry in China

摘要:

基于2000—2011年省级面板数据采用SFA模型实证分析了我国高技术产业技术创新效率及其影响因素,进一步通过Granger因果检验检测技术创新效率区域联动效应的存在性,并用VAR模型对该效应路径进行估计。研究表明：(1)高技术产业技术创新产出主要受研发资金投入影响,研发人员投入的作用不显著；(2)政府R D投入、自主创新倾向对技术创新效率的影响不显著,地区市场开放度对技术创新效率具有负面影响；(3)无论是在东、中、西三大区域之间还是在区域内部,高技术产业技术创新效率的地区差异都不明显；(4)技术创新效率存在区域联动效应,但这种效应仅发生在相邻地区,并且表现为中部到东部、中部到西部的单向局部正联动。

Abstract:

This article empirical analyzes technical innovation efficiency of high-tech industry and its influencing factors based on SFA model with panel data of 2000-2011, then study the effects of regional link by Granger casualty test and VAR model. Research finds: (1)innovation efficiency is influenced obviously by R D expenditure, but not by research fellows; (2)government R D expenditure, independent innovation tendency do not play notably effects, regional openness play negative effects; (3) technical innovation efficiencies of high-tech industry do not differ neither within nor among regions; (4) regional links effects just exist between adjacent regions, and are positive from the middle to the east and west.
