This paper analyses how technological and sectoral context structures influence the functional pattern of a focal technological innovation system (TIS), focusing on value chain interdependencies. Through a case study of the ‘embryonic’ bio-succinate from mixed food waste TIS in Sweden, we show that all identified context structures exert both negative and positive influences on TIS functions by influencing resource availability and accessibility, market conditions and the wider selection environment. Contextual influences result from interdependencies throughout the value chain, but in contrast to previous studies, direct structural overlaps are not as relevant as competition for resources, markets and policy support. Competition does not only come from the regime but also from other related TISs and sectors. The study also confirms the importance of contextual influences from the international TIS. These findings suggest that a wide perspective on context structures and selection pressures should be considered in future research.

本文分析了技术和部门环境结构如何影响焦点技术创新系统（TIS）的功能模式，重点关注价值链的相互依赖性。通过对瑞典混合食品废料TIS中的“胚胎型”生物琥珀酸酯的案例研究，我们发现，所有已确定的背景结构都通过影响资源的可获得性和可及性，市场条件和更广泛的选择环境，对TIS功能产生了负面和正面影响。上下文影响是整个价值链中相互依存的结果，但是与以往的研究相比，直接的结构重叠并不像对资源，市场和政策支持的竞争那样重要。竞争不仅来自政权，而且还来自其他相关的TIS和部门。该研究还证实了来自国际TIS的情境影响的重要性。这些发现表明，在未来的研究中应考虑对语境结构和选择压力的广阔视野。
