摘要：The present research aims to model effective functions on technological innovation system in biomass resources (livestock waste) in rural areas in Tehran province with emphasis on use of technological innovation system. Considering the nature of investigation, it is a type of quantitative and practical study with correlational measures. a survey was used to collect the required data. The population consists of all cattle owners in Tehran province that according to the Agriculture Jihad organization, they are 4677 subjects in 11 cities. Of these, 355 owners were selected via the Cochrans formula through stratified random sampling method. The SPSS software was a means to analyze the data. The main result of the current study is that socio-cultural functions of innovation, transfer, distribution, promotion, and training of technological innovative knowledge and formation of technology markets are of effective factors on use of biomass resources and the impact of three functions on using biomass resources is meaningfully increasing. Moreover, the result of present research is development of a mathematical model for maximizing the effective functions on technological innovation system of biomass resources. This result can be helpful for investigators, related organizations, users (rural areas in Tehran) and others.
