Modelling techno-sectoral innovation system A new hybrid approach for innovation motors policymaking

Purpose This study aims to scrutiny the performance of the petrochemical sector and the technological innovation life cycle. Also, the stage of the innovation life cycle for the sector is specified. Then, scenarios are designed to improve the speed of the sector development. For this reason, for synchronizing the petrochemical sector, this study tries to combine two innovation systems (technological and sectoral systems) called "techno-sectoral innovation system" under an integrated model. Furthermore, the "functions and driving motors" are expanded in the proposed model. Design/methodology/approach By combining two concepts of the innovation systems, the complexity of the system rises to some extent. Also, to model causal relationships in the sector and non-linear connections between variables, system dynamics approach is applied. During this phase, the flow diagram of the model is translated to a simulation programme using Vensim software. Model validation is investigated using a comparison of the actual with simulated values. Findings The results predict the functions state of the innovation system and detect activation of innovation motors in each stage of the innovation life cycle. Validation shows the acceptable error of the indices. It can be concluded that the sector is relatively in the development state. Four scenarios have been proposed for representing policies that sector uses to motivate its companies. The best scenario is the fourth one that divides resources with different weightings among companies to accelerate switching time between sector's motors. Finally, the fourth scenario can improve the performance of the petrochemical. Originality/value The hybrid approach shows researchers that performance of an industry can be improved based on sectoral and technological at the same time. Thus, this case-based model can contribute to other researchers, as a base model. Also, it could be customized with parameters and the relationship between players and functions. Furthermore, a dynamic switch among the motors has been presented in the model.
