In the context of economic transformation and the urgent need for technological modernization, Kazakhstan faces the challenge of building an effective corporate innovation system (CIS). The purpose of this study is to analyze the current state of the corporate innovation system, identify barriers and institutional constrains, and develop practical solutions to overcome them. The study is based on an empirical analysis of innovation activity dynamics, sectoral and regional disparities, investment structure, and institutional limitations affecting corporate innovation development in Kazakhstan. As a result, two complementary management models are proposed: the state-corporate model, focused on institutional support and coordination of innovation infrastructure, and the digital venture model, based on private initiative and flexible market mechanisms. It has been established that the most effective option is a phased combined approach, which implies a gradual transition from state-dominated incentives to a sustainable and self-developing innovation architecture. The value of the research lies in substantiating the institutional nature of existing constraints and in proposing a management framework that links innovation policy instruments with the level of corporate and regional innovation maturity. The scientific novelty of the research lies in the development of systemic models for managing the corporate innovation system, while the practical significance is determined by the possibility of applying these models in the design of national strategies, sectoral roadmaps, and corporate innovation development programs.
