道格拉斯模型在科技金融与经济发展关系分析中的应用

On Application of Douglas Model in Analysis of Relation Between Science Technology Finance and Economic Development

提出了一种包含科技金融投入因素在内的道格拉斯投入产出模型,用于分析科技金融和我国宏观经济发展之间的关系.以2000-2018年间的国内生产总值、社会投入资本、工业劳动力数量、科技金融演变指数为1个产出变量和3个投入变量的原始数据展开实证分析.中国宏观经济的增长,资本投入、劳动力投入、科技金融投入都起到了明显的推动作用,弹性影响因子都是在1%水平下显著.科技金融投入(K)对经济发展(G)的影响,4类评估得到的道格拉斯影响因子分别是0.2674,0.2711,0.2569,0.2883,虽然略有不同,但基本稳定在0.25~0.29的这个范围之内,说明科技金融对我国经济发展起到了重要作用.

In this paper,a Douglas input-output model including the input factors of science and technology finance has been presented to analyze the relationship between science and technology finance and China s macroeconomic development.Empirical analysis has been carried out with the raw data of GDP,social input capital,industrial labor force,science,technology and finance evolution index from 2000 to 2018 as one output variable and three input variables.China s macroeconomic growth,capital investment,labor investment,science and technology financial investment have played a significant role in promoting,the elastic impact factors are significant at the level of 1%.The Douglas influencing factors of science and technology financial input(K)on economic development(G)are 0.2674,0.2711,0.2569 and 0.2883,which are slightly different,but basically stable in the range of 0.25 to 0.29.This shows that science and technology finance has played an important role in China s economic development.
