ICT-based Collaborative innovation has a significant impact on the economy by facilitating technological convergence and promoting innovation in other industries. However, research on innovation suggests that polarization in firm size distribution, which has grown since the early 2000s, can interfere with collaborative innovation among firms. In this paper, I modelled firms’ decision-making processes that led to collaborative innovation as a spatial N-person iterated Prisoner’s dilemma (NIPD) game using collaborative innovation data from Korean ICT firms. Using an agent-based model, I experimented with the effects of firm size heterogeneity on collaborative innovation. The simulation experiment results reveal that collaborative innovation in the industry increases as the size heterogeneity decreases. Findings suggest that policies promoting collaborative innovation should focus on mitigating structural inequalities in the industry.

基于Agent的企业规模分布与协同创新模型

基于ICT的协作创新通过促进技术融合和促进其他行业的创新而对经济产生重大影响。但是，有关创新的研究表明，自2000年代初以来，企业规模分布的两极分化可能会干扰企业之间的协作创新。在本文中，我使用韩国ICT公司的协作创新数据对公司的决策流程进行了建模，这些流程导致了协作创新，即空间N人迭代囚徒困境（NIPD）游戏。使用基于代理的模型，我尝试了公司规模异质性对协作创新的影响。仿真实验结果表明，随着规模异质性的降低，行业内的协同创新不断增加。
