The system and factor analysis of innovation development in leading chemical and petrochemical companies was carried out on the basis of the most significant indicators. This analysis involved the whole ensemble of companies and information aspects (regional, industrial, time and others). For the purposes analysis the Innov-Chem 1.0 analytical information system has been developed. This system is a multicomponent structure consisting of several units. Such a software designing principle enables the addition and deletion of any functions to increase the system flexibility and scalability. The information about innovation activities from 2000 to 2019 collected by 165 leading companies of the chemical and petrochemical industries was used as the database for the studies. Such information about innovation activities is submitted to the Russian Ministry of Industry in annual statistical reporting forms (4-Innovation).
