AbstractThis paper analyses Lithuanian Maritime Sectors Economic impact to the whole Lithuanian economy by using those economic indicators: Capital investment share, Value Added at Production Cost, Turnover, Total Operating Profit, Number of Employees and Number of Enterprises. Official statistics does not present entire Maritime Sector in numbers as it is divided into the “sub- sectors” as the economic activities of the statistically presented economic group consisting of 4-digit level classes. The whole Maritime sector is important to be noted in statistical numbers, because mostly less impact is considered to be a serious risk for the diverted investment in specific sectors of the economy efficiency.
