政府支持企业R&D的政策模拟研究:基于改进的Nelson—Winter模型
Research on the Policy Simulation of Governmental Prompting on R&D in Enterprise:Based on the Modification of Nelson-Winter Model
【摘要】 技术是经济发展的重要动力,政府在推动企业R&D中采取何种有效政策值得深入研究。在改进Nelson—Winter经典演化经济模型的基础上,引进政府税收因素,研究了政府鼓励创新性R&D政策和鼓励模仿性R&D政策在不同行业的效果。模拟结果发现,对于垄断性行业,政府鼓励创新性R&D要优于鼓励模仿性R&D;而对于竞争性行业,政府鼓励模仿性R&D要优于鼓励创新性R&D。
