| Abstract [eng] |
The main goal of the doctoral thesis is to develop a model, based on the analysis of scientific literature on family farms‘ investment in agricultural machinery, which could help making such investment decisions that could ensure the growth of efficiency of investment in agricultural machinery and create preconditions for more efficient activity of family farms. The following key objectives are addressed in the doctoral thesis: having analyzed the respective scientific literature the aim is to identify the determinants of investment in the context of the development of investment theories, peculiarities of family farms‘ investment in agricultural machinery, the impact of support on these investments and their trends in the post-industrial economy, to develop a model that could ensure investment decisions leading to the growth of the efficiency of investment in agricultural machinery and create preconditions for more efficient activity of family farms, to evaluate the impact of investment implemented in Lithuanian family farms on family farms efficiency, to empirically verify the adaptability of the developed model, and to make recommendations on application possibilities of the developed model and further fields of research. The doctoral thesis consists of the introduction, three chapters, general conclusions, lists of literature and publications of the author on the topic of the doctoral thesis. The introduction defines the research problem, relevance, object, aim and objectives, research methodology, scientific novelty, practical value and statements to be defended. It also summarizes the publications and conference presentations of the author on the topic of the doctoral thesis. The first chapter presents an overview of investment theories for identifying determinants of investment, reveals peculiarities of family farms‘ investment in agricultural machinery, analyzes the impact of support on these investments, and identifies their trends in the post-industrial economy. The second chapter discusses the concept of efficiency and its measurement, presents the methodic for the assessment of dynamic efficiency of family farms in the context of investment spikes, and introduces a model of the acquisition of machinery services under the conditions of imperfect market of machinery services. The third chapter describes the investment activity of Lithuanian cereal and dairy farms, analyzes dynamic efficiency of Lithuanian cereal and dairy farms in the context of investment spikes, and assesses the possibilities of acquiring machinery services in various Lithuanian family farms of different sizes. 4 scientific articles have been published in peer-reviewed scientific journals and 4 presentations delivered at scientific conferences on the topic of the doctoral thesis. |
