三大技术创新主体科技成果与经济增长关系研究--基于国家创新体系与VAR模型的实证分析

摘要

According to analysis on the composition of main parts of technological innovation and each part's research traits and corresponding economic benefit ,this paper further analyzes the situation about relationship between main parts of technological innovation and economic increase .Bases on China's time series data from 1986 to 2011 ,uses vector autore‐gressive model ,granger causality test ,impulse response function and variance decomposition method ,and dynamically an‐alyzes relationship between S&T achievements from main parts of technological innovation and economic growth in China . Study show s that S&T achievements from enterprise have best effect on economic grow th ,and university is in second place .But research institutions have little push on economic growth compared with enterprises and universities .Combi‐ning with empirical analysis on China's output effect of S&T achievements from different main parts of technological inno‐vation ,puts forw ard relevant strategies to realize overall effect of S&T achievements from main parts of technological in‐novation for achieving most positive effects on economic grow th and finally makes a contribution to further study on indus‐try ,university and research cooperation and construction of nation innovation system .%在探讨技术创新主体构成、主体不同研究性质及对应经济效益的基础上，对产学研合作背景下的三大技术创新主体与经济增长关系进行了梳理。基于中国1986－2011年的时间序列数据，采用VAR模型，综合运用格兰杰因果检验、脉冲响应函数和方差分解，对中国不同技术创新主体的科技成果与经济增长进行了动态分析。研究表明，企业科技成果对经济发展成效较好，其次是高校，而科研机构科技成果对经济增长的促进作用比企业和高校小得多。结合中国不同技术创新主体的科技成果产出效应进行实证分析，为不同技术创新主体协同实现科技成果对经济增长的正向影响提出了对策建议。
