在平稳性检验、协整检验、格兰杰因果检验的基础上,建立SVAR模型。利用脉冲响应和方差分解技术对我国大中型工业企业的自主创新投入与产出进行实证分析。结果表明:自主创新经费投入强度、R&D人员投入强度和生产设备投入能力与创新产出之间存在着长期均衡的关系;R&D经费投入强度冲击、R&D人员投入强度冲击和生产设备投入能力冲击都会对自主创新产出产生正向的影响,其中生产设备投入能力的贡献最大,其次为R&D人员投入强度;R&D经费投入强度的增加对创新产出的影响具有长期的滞后性。
在平穩性檢驗、協整檢驗、格蘭傑因果檢驗的基礎上,建立SVAR模型。利用脈遲響應和方差分解技術對我國大中型工業企業的自主創新投入與產齣進行實證分析。結果錶明:自主創新經費投入彊度、R&D人員投入彊度和生產設備投入能力與創新產齣之間存在著長期均衡的關繫;R&D經費投入彊度遲擊、R&D人員投入彊度遲擊和生產設備投入能力遲擊都會對自主創新產齣產生正嚮的影響,其中生產設備投入能力的貢獻最大,其次為R&D人員投入彊度;R&D經費投入彊度的增加對創新產齣的影響具有長期的滯後性。

This paper establishes the SVAR model based on the stationary test, co -integration test and Granger causality test, and makes an empirical analysis on Chinese LME independent innovation input - output using the impulse response and variance decomposition technology. The results show that the R&D investment intensity, R&D personnel investment intensity and produc- tion equipment input capability have a long - term equilibrium relationship with the innovation output. The shocks which come from the R&D investment intensity, R&D personnel investment intensity and production equipment input capability have a posi- tive impact on the independent innovation output, and the production equipment input capability contributes the most while the R&D personnel investment intensity ranks the second in the contribution. However, there exists a long - term lagging between the increment of R&D investment intensity and its effect on the innovation output.
