中国大中型工业企业科技活动效率演化轨迹的实证研究

摘要

利用我国大中型工业企业科技活动基本情况数据,在统计回归的基础上,分别建立了非线性规划模型和动态优化模型,然后采用数学规划以及变分法对模型进行了求解和分析.研究发现,从动态优化的视角看,我国大中型工业企业科技活动效率指标的演化轨迹并不是最优的,提出了相应的政策建议.%This paper sets up the nonlinear programming model and the optimal control model of Chinese large and medium sized industrial enterprises,uses the mathematical programming and the method of calculus of variations to analyze the models.The research shows that the development path of Chinese large and medium sized industrial enterprises is not in a dynamic optimal state and it puts forward the policy suggestions.
