        Knowledge-Based services and high-tech industries contributions in Gross Domestic Product (GDP) of countris are increasing, since these contributions are reaching about 40 percent in countries such as USA. Entrance of Knowledge and technology elements in production function means an enormous increase in returns and ignorance from the daily importance of technology in economic growth and development will lead to a gap between developed and poor countries, exponentially. The present research reviewed the related literature of the three fields of science development, technology development and economic growth and their relationships thoroughly, and found 14 cofactors that affect the three fields and their relationships. Using experts' suggestions (13 Iranian experts which resides in Iran and abroad), the cofactors were applied in system dynamics approach in Vensim software to test the relationship and dynamics of the three fields in Iran in four different scenarios and in a 10-year period. The results showed that the three fields are interact with eachother in a complex, interwined structure in Iran and political- economic convergence is the key factor in this relationship. The results will be useful for policymakers of the three fields in Iran.   Manuscript profile

        The innovation ecosystem consists of a group of actors and dynamic processes that provide innovative solutions to new challenges. The main purpose of this research is to design a university-centered innovation ecosystem. For this purpose, ecosystem functions were first identified through literature review. Due to the limitation of As-Is data in Iran, interviews with stakeholders were chosen as a complementary technique. The second round of interviews were developed to identify the rules and processes of the ecosystem. The results of this study led to the choose Triple Layers core-periphery framework of innovation ecosystem called "Core-Platform-Development & Application". In this framework, the Institute of Health Technological Innovations is placed at the core layer, which is associated with these six platforms: Work Integrated Learning, Idea Generation, Entrepreneurship, Innovation, Shared Services, and Investment and Financing. Each of these platforms communicates with actors in that field at the Development & Application layer. After confirming the conceptual architecture with a triangulation technique, the ecosystem interaction model was designed & the results of the architecture in the case study were simulated by system dynamics method. For validation, the simulation results of the model under the two scenarios of continuation of the existing conditions and the establishment of the proposed architecture showed that the proposed architecture will clearly have a positive effect on the model variables in the future. Generally, the results obtained from the implementation of the model in favor of the implementation of architecture in the environment of innovation are studied in UT & TUMS Manuscript profile
