[Purposes] This paper aims to explore the relationship and evolution law between the generation, decision-making, implementation and evolution of green construction technology innovation intention in construction enterprises, and to provide theoretical reference for green construction technology innovation. [Methods] A dynamic evolution model of green construction technology innovation in construction enterprises is constructed by means of computational experiments, and the dynamic evolution process of innovation intention → decision → implementation → evolution is simulated by MATLAB2018b. [Findings] The innovative indicated an increasing and decreasing trend under the combined effect of innovation capability, competition level and environmental regulation. The innovation of green construction technology can significantly improve its greenness. Capital input and technology level are important factors affecting innovation performance and knowledge level is the biggest driving force of innovation. [Conclusions] A good innovation system environment can stimulate enterprise innovation enthusiasm, and the improvement of knowledge level and the overall control of innovation process are conducive to green construction technology innovation of construction enterprises.
