摘要
通过利用PVAR模型、脉冲响应函数和方差分解,对2002~2011年间江苏省R＆D投入、专利产出效率和经济增长实力的动态关系进行研究。结果表明,江苏省R＆D投入与经济增长实力存在双向的正效应,但这种影响并不具有持续性;专利产出效率促进了经济增长实力和R＆D投入的提高,但都存在1~2年的滞后期;R＆D投入和经济增长实力在短期内对专利产出效率均有负向影响。专利产出效率主要受自身和R＆D投入的影响,说明江苏省专利产出效率严重依赖于R＆D投入。
This paper uses PVAR model, impulse response function and variance decomposition analysis the dynamic relationship among R＆D input, patent output efficiency and economic growth strength over the period 2002 to 2011 in Jiangsu Province. Results show that there is a bi-directional effect between R＆D input and economic growth strength of Jiangsu province, but that effect is not sustainable; patent output efficiency improves the economic growth strength and R＆D input, but lagged in time periods; R＆D input and economic growth strength will have a negative impact on the patent output efficiency in the short term. Patent output efficiency is mainly affected by itself and R＆D input, it explains the patent output efficiency in Jiangsu Province relies heavily on R＆D input.
