【摘要】：借鉴现有技术创新相关研究,结合系统动力学理论方法,构建了医药产业技术创新系统动力学模型,刻画了技术创新系统内部要素以及要素之间的因果关系,深入分析了技术创新系统内部结构.利用Vensim软件绘制因果关系图和系统流图,分析技术创新系统的反馈回路,并对模型进行有效性检验,在此基础上进一步分析新产品比重、技术知识退化率和研发人员投入力度对医药企业技术创新的影响.研究结果表明,为保持技术创新能力,企业的新产品比重不宜过高;在技术知识退化率变大的过程中,企业应该更加注重技术知识的积累;提高研发人员投入力度未必能提升企业技术创新能力.
[Abstract]:Based on the existing research on technological innovation and the theory and method of system dynamics, this paper constructs a system dynamics model of technological innovation in pharmaceutical industry, and describes the internal elements of technological innovation system and the causality between them. The internal structure of the technology innovation system is deeply analyzed. The causality diagram and the system flow diagram are drawn by Vensim software, the feedback loop of the technology innovation system is analyzed, and the validity of the model is tested. On this basis, the proportion of the new product is further analyzed. The effect of technology knowledge degradation rate and R & D personnel input on technological innovation in pharmaceutical enterprises. The results show that the proportion of new products should not be too high in order to maintain the technological innovation ability, and in the process of increasing technology knowledge degradation rate, Enterprises should pay more attention to the accumulation of technical knowledge.
