This paper focuses on measuring the globally and nationally economic system’s connectedness and industrial sector’s function on the Global Value Chain (GVC) , as reinforcements to the present studies on international trade. Firstly, we reconsidered the length-related and position-related measures in literatures about vertical specialization from the perspective of econophysics. Secondly, we redefined the inter-country and inter-sector propagating process of intermediate goods and proposed the concept of Strongest Relevance Path Length (SRPL) based on Revised Floyd-Warshall Algorithm (RFWA) , which is the basis of new measurement. Thirdly, enlightened by betweenness centrality of node and edge, we introduced SRPL-based index to measure the Value-Added Pivotability of Industrial Sectors and Input-Output Relationships . Fourthly, we also proposed the concepts of Backward Closeness and Forward Closeness of Industrial Sectors based on closeness centrality.
