摘要:将科技投入量化为建筑业R&D经费内部支出、建筑业R&D人员、建筑业技术装备率,以扩展的经典柯布-道格拉斯生产函数模型和灰色关联模型为基础,分析2006~2016年我国建筑业科技投入对行业经济增长的影响,并建立分布滞后模型分析科技投入对行业经济增长的滞后性影响。结果表明:建筑业技术装备率对经济增长的影响最大,且滞后3~4年后科技投入各指标对经济增长的影响达到最大。

Abstract:This paper quantifies the investment in science and technology into indexes of R&D expenditure,R&D personnel and technical equipment rate of construction industry,and verifies and analyzes the impact of investment in science and technology on economic growth in China’s construction industry from 2006 to 2016 based on the extended classical Cobb-Douglas production function model and grey relational model. Then,establishes a distributed lag model to analyze the lagging effect of science and technology input on economic growth. The results show that,the rate of technical equipment in construction industry has the highest impact on economic growth,and after 3-4 years lag,the impact of S&T input on economic growth is the greatest.
Keywords:construction industry;investment in science and technology;extended production function model;distributed lag model;economic growth
