This study aims to conduct a functional analysis of the technological innovation system with the inclusion of sectoral and spatial perspectives. This involves the impact analysis of a variety of sectors’ integration into the biogas value chain and a more explicit review of spatial and institutional contexts of the transition process. By applying mixed methods research, this approach is illustrated by examining the development of the biogas industry in Russia. As a result, the adjusted framework enables us to understand how technological innovation develops, diffuses, and uses in specific segments and places. Such an advanced insight of the analyzed case also helps to give accurate recommendations for policymakers, researchers, and practitioners, who seek to initiate or expand the diffusion of biogas technologies in Russia.

本研究旨在对包含部门和空间视角的技术创新系统进行功能分析。这涉及对各种部门融入沼气价值链的影响分析，以及对转型过程的空间和制度背景进行更明确的审查。通过应用混合方法研究，通过检查俄罗斯沼气工业的发展来说明这种方法。因此，调整后的框架使我们能够了解技术创新是如何在特定领域和地方发展、扩散和使用的。对分析案例的这种先进见解也有助于为寻求在俄罗斯启动或扩大沼气技术传播的政策制定者、研究人员和从业人员提供准确的建议。
