以1980-2008年我国GDP产出、劳动力投入、资本投入、R&D投入和以论文合作为测度的弱隐性知识溢出(TKS)为基础,对弱隐性知识溢出与经济产出进行单位根检验、协整分析和因果检验,建立误差修正模型和脉冲响应函数,给出两者在长期、短期内的定量变动关系;同时利用金砖四国和日本、美国的数据对结果进行进一步验证。结果表明:无论是从长期均衡还是从短期变动来看,弱隐性知识溢出对产出的促进作用都是正向的,其与产出存在着Granger因果关系和长期协整关系,且短期影响显著。在我国R&D对TKS变动的脉冲反应最为明显。
On the basis of the weak recessive knowledge spillover (TKS) measured by GDP output, labor input, capital investment, R & D investment and paper measurement in 1980-2008, the unit root test of weak recessive knowledge spillover and economic output , Cointegration analysis and causality test, error correction model and impulse response function are established, and the quantitative relationship between the two in the long term and the short term is given. At the same time, the data are further validated by using the data from BRICS, Japan and the United States. The results show that, both from the perspective of long-term equilibrium and short-term changes, the promotion of weak recessive knowledge spillovers is positive, and there is a Granger causality and long-term cointegration relationship with output, and the short-term impact is significant . In our country R & D pulse response to changes in TKS most obvious.
