Gross value added in services - a case study of the sea port in Szczecin

The aim of the paper is to determine the size and structure of the Gross Value Added (GVA) generated by the supply of services in Szczecin seaport. Correlations, multipliers, and elas­ticities between different port services are indicated in the paper. The GVA is an economic measure of the size of generated production. In seaports, it expresses the value of the generated and delivered flow of services of warehousing and cargo handling, securing the safe movement and mooring of ships in port and their technical and commercial support, of accessibility to port infrastructure for in port manufacturers and port users, of organization, planning and coordination of processes of cargo and transportation units handling inside the port and at other nodes of the transportation chain. The scope of the research at Szczecin seaport included four groups of activities, namely: - cargo handling companies; - sea transportation support companies, including the ones supplying port shipping services (navi- gation, pilotage, and towage), dredging and underwater works (carried within the inner port basins), sea rescue, and other maritime services; - sea transportation agencies supplying services of port and maritime forwarding, shipbuilding brokerage, ship agencies, customs, maritime consulting and expertize, cargo stowage and secur­ing aboard the ship, cargo expertise and inspection, and other services (logistics); and - sea port authorities. GVA has been calculated by subtracting the value of the intermediate consumption from the gross output of the port sector companies. The intermediate consumption consists of the value of con­sumed materials and energy, external services, and the rest of the by nature costs of business entities. The GVA calculation has been based on the statistical data obtained from the Centre of Maritime Statistics at the Statistical Office in Szczecin.
