Contrary to the decline of the industrial and agricultural production, the contribution of services to GDP increased from 30 percent in 1990 to 51 percent in 1999. The most prominent segments of the service sector are tourism and financial services. The following services can be classified as relatively developed branches of service sectors in Ukraine: telecommunications services, banking services, advertising and public relations services, legal services, audit and accounting services, and tourism services. But the following service sectors are still quite underdeveloped: engineering, insurance, private health care, and security.
Transportation is another important sector of the services economy. Russia is highly dependent on Ukraine for its transport of gas to Europe. Ukraine has made several proposals in an effort to be included into the energy transport network for Caspian Sea energy resources. The dominant method of transporting goods in Ukraine is by trucks, though deteriorating roads and high fuel costs make trucking expensive.
