备注

依据科技资源投入与建筑业发展的耦合机理,构建了两系统综合评价指标体系。引用熵值法对指标客观赋值,利用协调度模型测算出2007—2017年两系统协调度,量化分析其协调状态。最后使用回归分析模型研究影响科技投入效率与建筑业发展水平耦合协调度的主要因素。结果 表明:1)研究期内,科技投入效率与建筑业发展水平两系统具有显著相关性,为研究的进行奠定了基础; 2)科技投入效率与建筑业发展水平两系统的协调系数逐年增大,协调状态趋向有序,但整体协调水平仍较低; 3)解释变量中,政府干预指数与耦合协调度呈现显著负相关; 从业人员受教育水平与被解释变量呈正相关; 市场发育指数不具有显著性。

Based on the coupling mechanism between the investment of science and technology resources and the development of construction industry, a comprehensive evaluation index system of the two is constructed. The entropy evaluation method is used to objectively assign the index, and the coordination degree model is used to calculate the coordination degree of the two systems in 2007—2017 to analyze the coordination state quantitatively. Finally, the regression analysis model is used to study the main factors that affect the coupling degree of the science and technology input efficiency and the construction industry development level. The results show that: 1)during the research period, there is a significant correlation between the scientific and technological input efficiency and the level of construction industry development, which lays a foundation for the research; 2)the coordination coefficient between the two systems has increased year by year, and the coordination status tends to be orderly, but the overall coordination degree is still low; 3)among the explanatory variables, the government intervention index and the coupling coordination degree shows a negative correlation obviously while the education degree of employees is positively correlated with the explained variables, so that the market development index is not significant.
