后疫情时代,世界各国采用科技创新券刺激企业间科技成果转化,已成为经济可持续和高质量发展的有效手段。本文构建了改进型最小成本-最大流量模型,模型中技术产品推广临界比例会调整节点企业的技术产品供给策略,通过数值假设模拟了三种场景。结果表明：(1)该模型能较好地解决科技创新券、技术产品推广临界比例和科技成果转化的优化问题;(2) 技术供给方可以转化类型多样且数量最大的科技成果,且政府科技创新券的发行额度能够达到最低;(3) 技术产品推广临界比例的高低会影响技术供给方的科技成果转化效果。提出了相应的建议,希望能更好地帮助政府实施科技创新券政策来加速科技成果在企业间的扩散应用。

In the post-epidemic era, the adoption of innovation vouchers around the world to stimulate the transformation of science and technology(S T) achievements among enterprises has become an effective tool for sustainable and high-quality economic development. In this paper, an improved minimum cost-maximum flow model is constructed, in which the critical ratio of technical product promotion will dynamically adjust the technical product supply strategies of nodal firms, and three scenarios are simulated by numerical assumptions. The results show that: (1) The model can effectively solve the optimization problems of innovation vouchers, critical ratio of technical product promotion and transformation of S T achievements; (2) Technology suppliers can transform the largest number of scientific and technological achievements of various types, and the issuance quota of government"s innovation vouchers can reach the lowest; (3) The size of the critical ratio of technical product promotion will affect the effect of S T achievements transformation from the technology suppliers. The recommendations were made, hoping to better help the government implement the innovation voucher policy to accelerate the diffusion and application of technological achievements among firms.
