产学研合作创新方式下政府补贴策略选择

摘要

创新补贴策略是政府鼓励企业创新的一种常见政策,考虑到企业内在的吸收能力与外部不同政府补贴策略方式的存在,本文以产学研合作创新方式为基础,通过建立三阶段博弈模型,利用模型解析与仿真分析讨论吸收能力与创新投入分配比例系数对政府补贴策略选择的影响.研究结果表明:无论政府采取哪一种补贴方式,均可以有效激励企业加大创新投入规模,并且企业的吸收能力与R&D投入、产量及社会福利均呈正相关关系;但是,吸收能力对利润及政府补贴的影响受限于补贴方式和企业的创新投入分配比例系数;此外,在创新产品补贴下,创新难度系数对政府补贴额度的影响并不明显,而创新产品补贴总体优于创新投入补贴.%The subsidy strategy is a common policy that governments encourage enterprise innovation.Concerning the inherent absorptive capacity and external government subsidy strategy, this paper, by establishing a three-stage game model,uses the analytical solution and simulation analysis method to explore the influence of absorp-tive capacity and innovation distribution input coefficient on the government subsidy strategy,based on industry-university-research cooperative innovation.The results show that:no matter what hind of government subsidy,it can motivate enterprises to enlarge innovation investment scale.The enterprise absorptive capacity,R&D input, output and social welfare show a positive correlation,but absorptive capacity's impact on profits and government subsidies are limited to subsidies mode and the enterprise innovation distribution coefficient.Under the innova-tive products subsidy,the influence of innovation difficulty coefficient on government subsidy is not obvious, in contrast,innovative products subsidy is superior to innovation input subsidies.
