Introduction 
Today, on the one hand, rapid changes in work and life environments, and on the other hand, the requirement of capital infrastructure have led to significant economic urban development (multidimensional flow). What’s more, the main basis of economic development and being in the flow of sustainable development (for cities) are based on innovations, which is a city-oriented capital and catalyst of economic development. “Innovation Area” creates a suitable environment for innovative centers, makes society more dynamic at the heart of sustainable development, and brings about a knowledge-based and innovative economy. This is an environment aiming to create value for increasing standards, quality of life, and entrepreneurship; that is, it leads to the economic development of neighborhoods. Modares Innovation District (MID) sets out to create a correlation circle between the business world and the academic world(universities). It is planning and developing to accelerate and fasten the process of making a knowledge-based economy, growth of innovations, training skills, and increasing the quality of people’s lives (neighborhoods). In other words, one of the most critical properties of Modares innovation district is the connection between anchor pioneering institutes, that are in clusters of start-ups, growth centers, businesses, and accelerators alongside the innovation hubs. It seems to be true to say that these areas try to create economic, social, and physical networks in a growing context where start-ups and different economic firms in the context of knowledge, technology, and innovation hub (Tarbiat Modares University) have moved on. Also, Modares innovation area, with h knowledge-based economy, using social innovation, overcomes two challenges in sustainable development: socio-physical redevelopment and balancing job and housing issues. 
Materials and Methods
This project sets up to answer the challenges and goals of innovation districts by choosing some information based on case studies and the framework of concepts analyzed in the area of innovations. The data of this research have been collected in library methods. Also, cluster analysis and questionnaires (specialists in urbanism, economic, and social spheres) have been applied to recognize and evaluate the process of the innovation district. Moreover, the combination of AHP technic with GIS through Marinoni program in GIS, has been used by means of resultant coefficients of analyzing of specialists.
Findings
One of the most important strides of this project is to achieve the concepts of innovation districts, their resultant experiences of recent years, and the way to respond to people’s needs, especially social ones. In this research, deep recognition of the theoretical framework of innovation districts and identifying of main parts of these areas have been done. Moreover, the function of these areas has been evaluated to lead the impacts of development to the right path by means of the last experiences of policy-making patterns of innovation districts. Evaluations in this project are carried out in three steps: 1- indicator-making, 2- introducing physical and spatial structure and networking, and 3- analyzing the probable impacts of elements of the innovation district. In the first step, this project recognizes and analyzes the innovation district by means of recognition layers of the innovation area. The second step evaluates possible and actual networks and impressive and impressionable elements like physical and spatial structure, and the third step evaluates the influence of elements in the Modares innovation district.
Conclusion
This project tries to recognize various impacts of MID development so that it can provide a specific pattern for controlling, leading, and making balance among actors of this district. The results of the analysis have emerged as “the pattern of policy-making for Modares innovation district development” showing MID needs a local policy-making system. Eventually, the results of this project are presented in 3 phases. Firstly, development impacts on assets of the innovation district have been evaluated, then controlling levers for these impacts have been introduced, and finally, patterns of policy-making and solutions for controlling and leading the development effects on the innovation district have been shown. Lastly, creating enterprise networks to develop businesses in a knowledge-based economy context is the most important goal of this project. To achieve success of this area, some user-based policies with collaborative leadership have been considered as essential results. On one hand, recognizing and introducing some catalysts for creating and leading a growing context, and on the other hand considering some levers for controlling the impacts of development are the most important factors of policymaking in innovation areas. Some solutions have been considered as private and public collaborative tools. Results show that the most important and influential element of Modare’s innovation area is enterprise. Modares University and Modares Science and Technology Park play a key role as the hub and main anchor of this innovation area.
