This research was conducted with the aim of determining the qualitative development model of the universities' Incubators of Iran, using the tradition of qualitative research based on Grounded theory , with Strauss and Corbin's approach and paradigmatic logic. This study conducted interviews with 15 managers of the Incubators in Iran . The sampling was carried out through theoretical method and according to the type of coding, the data analysis was based on three stages of open coding, axial coding and selective coding. From analysis of interviews in the coding phase of 204 concepts, in the pivotal coding step of 60 sub categories and in the selected coding stage, 23 categories were categorized. The results of Pajhwah showed: The causal conditions of the paradigm of qualitative development of the centers of growth of the universities consisted of 6 main components (organizational framework, educational factors, financial factors, communication patterns, effective teamwork, market research). Underlying conditions include three main categories (function, economy, rules). The Substance and intervention conditions include the four main categories (support, empowerment, attitude, interpersonal analysis), paradigm strategies including five main categories (distinction, reward, scientific attraction, development development, financial support), qualitative development paradigm implications including 5 main categories (Rich and reinforced employment, entrepreneurship growth, talent management, scientific marketing).

The aim of this study was to evaluate the role of facilities of incubators in growth of new technology based firms (NTBF's). Statistical population is the NTBF's located on incubators and technology parks in Mashhad city. Data collecting tools is questionnaire made by the researcher. For data analysis, correlation and stepwise regression were used. The results showed that an increase in facilities of incubators, NTBF's will be more growth oriented. There is a significant and positive correlation between the facilities of incubators and growth of NTBF's (r=.871). As well as, all components of incubators (establishment in the center, advice provided, benefits of being in the center and services and facilities of the existing infrastructure) with the growth of new technology-based firms (growth in sales, employment and profitability) have a significant positive relationship. The results of stepwise regression analysis show that components of establishment, advice provided, benefits of being in the center and the services and facilities of the existing infrastructure in the incubators, together jointly explained 0.914 of the variance of performance
