本文在分析科技产出对科技投入影响机制的基础上构建研究框架,运用面板数据、格兰杰因果检验、面板VAR模型研究了科技投入与产出的互动关系,侧重不同投资渠道资金的绩效研究。研究结果表明,政府科技投入具有一定的刚性,相对独立,不能带动企业科技投入。企业科技投入与银行科技贷款的结合相对比较紧密。科技产出除对企业科技投入的具有较大的促进作用外,对其他投入要素的反馈较小。从要素贡献看,政府科技投入的弹性系数大于企业科技投入,银行科技贷款的弹性系数为负数,研发人员全时当量与科技产出无关。
Abstract
This paper establishes a study framework based on the analysis of the interactive influence mechanism of S&T input and output, then analyzes the Interactive relationship between S&T input and output based on panel data, Granger causality, pane VAR model, focusing on the performance research of funds from different financing channels. The research results show that the government S&T input has a certain rigidity and relative independence and cannot drive the enterprise S&T input. The enterprise S&T input and the S&T bank loan combine relatively more closely. The S&T output has greatly promoted the enterprise S&T input and the feedback to other elements is small. From the perspective of the factor contribution, the elastic coefficient of the government S&T input is greater than that of the enterprise S&T input while the elastic coefficient of the S&T bank loan is negative and the R&D labor is independent of the S&T output.
