[Objective] During project delivery, construction companies must solve technical problems, coordinate complex relationships among stakeholders, adapt to changing client demands and the external market, and consider environmental protection and social development. To this end, construction companies must innovate to improve their competencies. Achieving innovation has become a critical issue for the construction industry. Most existing studies exploring the promotion of construction innovation lack an overall perspective to analyze the impact of innovation management mechanisms on the integration of innovation resources and activities and rarely consider the critical roles of both engineering project innovation and company innovation ability. Therefore, this study comprehensively and systematically reveals the status of innovation in the engineering construction industry. It analyzes and evaluates the company innovation system, inter-organizational knowledge sharing, project implementation processes, and engineering project innovation. [Methods] From the perspective of the construction industry, this study systematically analyzes construction companies' innovation through questionnaire surveys and interviews to build a theoretical model of the construction industry's innovation. The relationships between company innovation systems, inter-organizational knowledge sharing, project implementation processes, engineering project innovation, company innovation ability, and company performance are revealed. In this study, 118 companies in China from the construction industry were selected, and a total of 500 questionnaires were issued to the owners, the designers, the constructors, and the supervisors from the companies, of which 431 were deemed valid. In addition, 110 technical and management personnel from 12 companies were interviewed via on-site and telephone interviews to determine their perspectives and knowledge of innovation in construction industry to provide in-depth interpretations of the quantitative analysis. [Results] The results show that the company innovation system can affect inter-organizational knowledge sharing and the project implementation processes, promote engineering project innovation, improve company innovation ability, and achieve company performance improvement. [Conclusions] This study systematically analyzes the construction industry's innovation, constructs a theoretical model of construction companies' innovation, comprehensively considers the innovation of engineering projects and company innovation ability, and reveals the influence mechanism of construction companies' innovation and its crucial role in company performance. The model is verified using questionnaire surveys and expert interviews. The results indicate that the company innovation system can affect inter-organizational knowledge sharing and the project implementation processes, promote the innovation of engineering projects, improve company innovation ability, and finally improve company performance. These results provide essential theoretical and practical guidance for construction companies.
