The purpose of this work has been to investigate changes in interdependencies between Norway's mainland industry sectors and how it might affect national security. To this end, the interdependencies were analysed by using the demand-reduction inoperability input-output model and national account data for the time period 2012–2017. The construction sector and the food industry sector are very important industries for mainland Norway. The construction sector has also increased its influence from 2012 to 2017. Because of the large influence these sectors exercise on other sectors, disruptions to the construction sector or the food industry may seriously impact the national security of Norway. Norway's agricultural sector, in particular, is very fragile towards disruptions to the food industry. Efforts to enhance the resilience of the agriculture and the food industry should therefore continue. With increasing digitisation and automation of the construction industry, it is necessary to get more knowledge on how this will affect the interdependencies between the construction industry and other sectors, and the potential vulnerabilities that follows. It is also recommended to gain more knowledge about the importance of the construction sector and construction workers for maintaining critical national infrastructures during crises.

这项工作的目的是调查挪威大陆工业部门之间相互依存关系的变化及其对国家安全的影响。为此，使用减少需求的不可操作性投入产出模型和2012-2017年期间的国民账户数据对相互依赖性进行了分析。建筑业和食品工业是挪威大陆非常重要的产业。从2012年到2017年，建筑行业的影响力也有所提高。由于这些行业对其他行业的影响很大，对建筑行业或食品行业的破坏可能会严重影响挪威的国家安全。尤其是挪威的农业部门，在破坏食品工业方面非常脆弱。因此，应继续努力提高农业和食品工业的复原力。随着建筑业数字化和自动化程度的提高，有必要获得更多有关这将如何影响建筑业与其他部门之间的相互依赖性以及随之而来的潜在漏洞的知识。还建议进一步了解建筑行业和建筑工人在危机期间维护重要的国家基础设施的重要性。
