摘要
以人均GDP作为经济增长的代理变量,分别使用财政科技投入、R&D经费投入作为科技投入的代理变量,研究了科技投入与经济增长的关系。研究表明:科技投入与经济增长的关系是非线性的,适合使用非线性平滑转换模型来拟合。财政科技投入与经济增长的关系存在两个门限,其转换变量为前一期的经济增长速度;R&D经费投入与经济增长的关系存在一个门限,其转换变量也是前一期的经济增长速度。
This paper analyzes the relationship between science and technology investment and economic growth, applying GDP per capita as a proxy of economic growth, /neanwhile using financial technology investment, R＆D expenditure as a proxy of investment in science and technology. The results show that： the relationship of science and technology investment and economic growth is nonlinear, and suitable to use nonlinear smooth transition models to fit. There are two＇ thresholds on fiscal expenditure of science and technology and economic growth. Conversion variable of the model is the rate of economic growth of previous one period. When the speed of economic growth dropped quickly or rose quickly, the nonlinear influence of fiscal expenditure on science and technology on economic growth will appear. There are one threshold on R＆D expenditure and economic growth. Conversion variable of the model is the rate of economic growth of previous one period, too. When the speed of economic growth rose quickly, the nonlinear influence of R＆D expenditure on economic growth will appear.
