Entrepreneurship is considered to be one of the key elements of economic prosperity and economic recovery, while entrepreneurs are seen as drivers of the economy. In this master thesis the author studies entrepreneurship, enterprises, and entrepreneurs in order to analyze their influence on the economy, and analyze their business environment. The paper seeks to determine the state of entrepreneurial environment and the conditions that Croatian entrepreneurs face through starting a venture, running and operating it, and eventually closing the venture. The entrepreneurial environment is determined through a number of factors such as ease of starting a business, dealing with construction permits, getting electricity, registering property, getting credit, protecting minority investors, paying taxes, trading across borders, enforcing contracts, and resolving insolvency. Furthermore, movements of entrepreneurial economic results through the years are observed in order to realize the effects of the global economic crisis of 2008. The paper also analyzes entrepreneurship in Croatia compared to other countries in the world through the Global Entrepreneurship Monitor, where it is ranked fairly low in many of the categories. Lastly, the paper shows and analyzes the 2008 global economic crisis and its effects on the global economy. In spite of predictions of the 2008 crisis, its global influences, or effects, were underestimated. In this chapter the author presents the causes of the crisis, the key events and practices that preceded it, the development of the crisis through the years, and, finally, the crisis influence on entrepreneurship in Croatia. Based on the implemented analysis of economic factors that influence the entrepreneurship environment, the key faults in Croatian entrepreneurship practices and policies are discerned. Some of these include a lack of timely and proper reforms, obsolete and insufficient entrepreneurship support, complicated and expensive processes, etc. Said problems influence the entrepreneurial environment and the competitiveness of Croatian enterprises, where through a lack of efficient organization and support systems there is no progress in global competitiveness.
