Recent global turmoil has added to the importance of food security issues and the sustainability of production processes worldwide. This study aims to uncover the degree of domestic industries' dependence on the international fragmentation of production processes and identify the countries of origin of those producers who have managed to displace domestic producers in corresponding Global Value Chains. Using data retrieved from the World Input-Output Database, we studied Czechia's example via demarcation of domestic value-added (DVA) shares from foreign ones in final domestic products. A declining trend in DVA signalises an ever-increasing dependence on foreign inputs. The conducted analysis allowed a VA-structure (and its dynamics for a sequence of years) to be clearly identified for final domestic products among 30 industries that virtually cover the entire economy. The most alarming finding is the marked reduction of DVA in food manufacturing, which points to a weakening of Czech food security. Realising all the connections within GVCs may help to identify vulnerable spots in domestic production processes and prepare adequate response mechanisms in potential situations of possible interruptions from the foreign side. The detailed explanation of the decomposition technique provided in the study can be used in similar analyses of other economies to reveal noteworthy trends and prepare response measures.
近期的全球动荡加剧了粮食安全问题以及全球生产过程可持续性的重要性。本研究旨在揭示国内产业对生产过程国际碎片化的依赖程度，并确定在相应全球价值链中成功取代国内生产商的那些生产商的原产国。利用从世界投入产出数据库检索到的数据，我们通过划分最终国内产品中来自国外的附加值（DVA）份额，以捷克为例进行了研究。DVA的下降趋势表明对外国投入的依赖日益增加。所进行的分析使得能够明确识别几乎涵盖整个经济的30个行业中最终国内产品的附加值结构（及其多年来的动态变化）。最令人担忧的发现是食品制造业中DVA的显著下降，这表明捷克粮食安全在减弱。了解全球价值链中的所有联系可能有助于识别国内生产过程中的薄弱环节，并在可能受到外国干扰的潜在情况下制定适当的应对机制。该研究中提供的分解技术的详细解释可用于对其他经济体进行类似分析，以揭示值得关注的趋势并制定应对措施。
