目前关于建筑行业创新投入、技术扩散、对建筑产业整体收益、产业集中度的影响难以用实际数据分析,因而从个体企业行为角度出发,根据多智能体理论,使用多主体仿真平台(Netlogo)建模平台,建立我国建筑业的交易行为互动流程,模拟运行建筑产业创新行为,观察并分析论证创新使产业集中度产生波动,创新企业数量与产业收益是U型关系,技术扩散速度对产业收益有极大影响的结论。 At present, it is difficult to analyze the impact of innovation investment and technology diffusion in the construction industry on the overall revenue and industrial concentration of the construction industry with actual data. Therefore, from the perspective of individual business behavior, using the multi-agent simulation platform (Netlogo) Model platform, the establishment of China’s construction industry interactive trading process flow, simulation of building construction industry innovation behavior, observation and analysis of innovation to make industry concentration fluctuations, the number of innovative enterprises and the industry income is a U-type relationship, the rate of technological diffusion of industrial profits have Very influential conclusion.
