The article addresses pressing issues concerning the assessment of the economic efficiency of innovative development in agricultural enterprises in the Republic of Kazakhstan. These issues stem from the systemic transformation of the sector, global food security challenges, climate change, and the imperative for technological modernization. Gaps in existing methodological approaches have been identified, such as insufficient inclusion of institutional specificities, natural and climatic factors, and the organizational and economic heterogeneity of the industry. The objective of this research is to systematize and critically analyze methodological approaches to assessing the economic efficiency of innovative development in agricultural enterprises, considering the specific context of Kazakhstan. The methodological foundation is based on systemic and comprehensive approaches, as well as a systematic literature review using an adapted PRISMA 2020 protocol. The source selection procedure included searches in Web of Science, Scopus, RSCI, KazNEB databases, and repositories of international organizations. The originality and value of the research lie in identifying five key gaps in existing methodological approaches and proposing a conceptual framework for a four-level assessment, adapted to the conditions of Kazakhstan's agricultural sector. The novelty of the framework lies in integrating a contextual level, combining institutional and climatic factors, with standard assessment levels. The research results enabled the formulation of a conceptual framework for assessing the economic efficiency of innovative development in agricultural enterprises in Kazakhstan. This framework integrates financial-economic, production-resource, innovation-performance, and institutional aspects. Five priority directions for adapting methodological tools are proposed, introducing a subsidiarity adjustment factor, stratifying assessment by agro-climatic zones, developing specialized statistics, differentiating methodologies by the scale of economic entities, and evaluating digital innovations. The findings highlight the multidimensional nature of innovative development outcomes in the agro-industrial complex and the need for further empirical validation of the proposed framework.
