The transportation sector is the lifeblood of an economy. It is divided into three principal categories, i.e., modes of transportation: air, land, and water. This paper analyzes the post-financial crisis value added data for the Croatian economy (2008–2015) by analyzing the dependence of three categories of the transportation sector on the cumulative of all other sectors, and on the manufacturing sector in particular. The value added of the three categories of the transportation sector is progressively dependent on the value added of the cumulative industry. This may be due to the progressive dependence of the gross national product on transport because of specialization and division of labor resulting in economies of density due to network and agglomeration effects.

克罗地亚交通运输对工业的依赖

运输部门是经济的命脉。它分为三大类，即运输方式：空运，陆运和水运。本文通过分析运输部门的三类对所有其他部门（尤其是制造业）累积的依赖性，分析了克罗地亚经济（2008-2015年）的金融危机后增值数据。交通运输行业的三大类别的增加值逐渐取决于累积行业的增加值。这可能是由于专业化和分工导致国民生产总值对运输的逐步依赖，由于网络和集聚效应而导致了密度经济。
