СОЦІО-ЕКОЛОГО-ЕКОНОМІЧНИЙ ЕФЕКТ РЕЗИСТЕНТНОСТІ ПОРТОВИХ СИСТЕМ У ЗАБЕЗПЕЧЕННІ ЯКОСТІ ЖИТТЯ ПРИМОРСЬКИХ ТЕРИТОРІЙ

The paper substantiates the scientific and methodological foundations for assessing the socio-ecological-economic effect of resilience in port systems as an integral factor of quality of life in Ukraine’s coastal territories during post-war recovery. The concept of “port system resilience” is defined as a multidimensional property combining socio-ecological-economic and cognitive-institutional stability. Within the Resilience+ framework, a structural-analytical model is proposed to evaluate resilience through four subsystems (social, economic, ecological, and cognitive-institutional) - allowing assessment of their balance and impact on community welfare. A five-level threshold scale of the socio-ecological-economic effect (from critical to reference level) is developed, highlighting that resilience represents both a quantitative indicator of efficiency and a marker of civilizational maturity, reflecting synergy between development, responsibility, and cohesion.
