Ports are what initiate the social and economic growth of a region, not only enabling trade but also serving as a center for social activities. Nowadays, most ports (especially seaports) are well equipped with specialized machinery such as forklifts and gantry cranes to facilitate regular cargo transactions. Ports are also a major source of employment as a large number of workers are employed there.

The paper deals with changing roles of economic growth sources in the context of historic development, attempting to determine
factors adequate to modern requirements. Four stages of civilization process development are identified, each with a specific combination of growth sources. The paper puts forward a theoretical thesis formulated on the basis of American statistical data. The thesis stating that in the modern industrial-informational economy one of the coordinate axes of growth factor space represents physical and another one – intellectual capital, has received some empirical validation. It has been demonstrated that significant build-up of intellectual product share in production investments in 1983 – 2003 laid down the grounds for unit investment stabilization, thus, accelerating the average annual labor productivity growth rate. A modest growth of intellectual product in 2004 – 2016 proved inadequate to counter a marked growth in demand for capital.

Evaluation of public investment efficiency in macroeconomic terms has increased the attention of the researchers in recent years. In this paper we concentrating on the evaluation of public investment based on the impact they have on the economic indicators and specifically the growth of private investment. Public investment at national and local level have an important role in economic growth and particularly public infrastructure contributes in increasing private investment, in the developing economies. In this regard, in our paper we get in study investment in public infrastructure and their impact on the number of private businesses in the municipality of Saranda. In the first part of this paper is treated the theoretical aspect of public investment, identification of economic indicators and evaluation of public investment on the basis of these indicators. In the second part we have treated methodology for collecting and processing data. For the realization of our paper, we are based on a statistical study of secondary data and to process them is using linear regression model. Data analysis represents the third part of the study, namely the correlation analysis of independent variables and the construction and analysis of linear regression equation, which expresses the connection of independent variables with the dependent variable. The ratio of public investment in infrastructure to public investment total, represent independent variable with the more important that we have included in our study, interest rates and the index of economic freedom represents independent explanatory variables, while number of business entities represents the dependent variable.

Many studies in recent years have shown that remittances constitute one of the most important financial resources for developing economies. They are considered as sustainable capital resources and in this way contribute to a sustainable economic growth in developing countries. Today, the flow of remittances at a global level reaches more than US $ 100 billion per year, and more than 60 percent goes to developing countries. They are an important mechanism to transfer resources from developed countries to developing countries. In this way remittances particularly in the developing economies play an important role in economic growth and poverty reduction. In this regard, in our paper we get in study remittances and their evaluation on the basis of the impact on economic growth in Albania. In the first part of this paper is treated the theoretical aspect of remittances and their role in economic development. In the second part we have treated methodology for collecting and processing data. For the realization of our paper, we are based on a statistical study of secondary data and to process them is using linear regression model. Data analysis represents the third part of the study, namely the correlation analysis of independent variables and the construction and analysis of linear regression equation, which expresses the connection of independent variables with the dependent variable. Remittances represent independent variable with the more important that we have included in our study, foreign direct investment and net exports represents independent explanatory variables, while economic growth represents the dependent variable.
