摘要
为了研究企业科技创新系统中各变量间的非线性动力学行为,实现效益最大化,构建了三维动态非线性模型,通过仿真分析了参数与初值变化对系统的影响,并进行实证分析.研究结果表明:研发投入和新产品收益本身存在线性关系,受专利数量的影响,二者之间的相互关系由类线性关系趋向非线性;混沌吸引子的存在会导致企业新产品收益、专利数量以及R&D经费投入量之间的关系经过一段时间的变化后趋于稳定;企业专利数量的发展速度存在合理区间,处于合理区间内的企业专利发展速度会使新产品收益在研发周期内实现效益最大化.
In order to study the nonlinear dynamic behavior among various variables in the enterprise technological innovation system and maximize benefits,this paper constructs a three-dimensional dynamic nonlinear model,analyzes the impact of parameter and initial value changes on the system through simulation,and conducts empirical analysis.The research results show that there is a linear relationship between R&D investment and new product revenue.Due to the impact of the number of patents,the relationship between the two will shift from a quasi linear relationship to a non-linear one.The existence of chaotic attractors will lead to a stable relationship between the revenue of new products,the number of patents,and the amount of R&D investment after a period of time.There is a reasonable range for the development speed of the number of enterprise patents,and the development speed of enterprise patents within a reasonable range will maximize the benefits of new product revenue within the research and development cycle.
