Global and crisis transformations result in structural and functional changes in the tourism system, which combines resource potential, infrastructure, tourism entities, institutional structures, and consumers. For Ukraine, with its high tourist potential, tourism development is a significant factor after the crisis recovery of the economy. Overcoming the disparities in the tourism system functioning, shaping optimal business models of its development, increasing the sustainability and efficiency of the tourism entities functioning impose an objective need for investment. Investment attractiveness is one of the key characteristics causing the investor’s interest in financing the project, including the tourist one.
The essence, determinants of influence and characteristic features of investment attractiveness of the Ukrainian tourism system are substantiated. The investment attractiveness of the tourism system is proposed to be considered as a complex feature of conditions and advantages that form its ability to attract investment resources based on the availability of their needs, unique tourist potential, favorable environment for ensuring the efficient functioning of the tourism system and guaranteeing the investor profit and reduced risks of investing.
The article considers basic preconditions to form the investment attractiveness of the tourism system, which include unique strategic opportunities, to shape a favorable institutional environment and provide a background for an investor concerned and a system of guaranteeing the expected result.
Given the need for complex consideration of the tourism system’s investment attractiveness, a methodology based on the calculation of integrated indicators for estimating the effectiveness and prospects for the development of tourism systems in the Ukrainian regions is used. In the method considered, it is proposed to take into account not only financial aspects, but also the resource potential, its development level, the growth rates of tourism entities activities, and the prospects for the tourism system development. In general, indicators and criteria for the tourism system investment attractiveness are classified into four groups: the efficiency of investment, the effectiveness of the tourism system development, the prospects for the tourism system development, the environment and the potential for its development.
According to the method developed, the integral indicator of investment attractiveness of the tourism systems of Ukrainian regions has been calculated, and the regions are differentiated according to the level of investment attractiveness. Estimation of the investment attractiveness of Ukrainian tourism systems allows to determine their rating, differentiate them according to the maturity level of complementary preconditions to form and develop tourist potential and serves as a basis for potential investors in investment decisions-making.
Using the results of determining the level of investment attractiveness of tourism systems of Ukraine’s regions over time will help identify trends, and, accordingly, serve as a guide for potential investors in strategic proposition space of regions which are investment recipients.

The development and implementation of regional tourism development programs in Ukraine require the formation of the information environment for ranking the tourist systems of Ukraine’s regions according to the attractiveness of their investment potential, which determines the purpose of this study. The methods of economic analysis and rating modeling were used to rank regional tourism systems according to their investment potential by determining the integral indicator of the economic and tourist resources of each region. Accordingly, economic indicators are chosen to provide the regions with financial, labor, and production resources; tourism indicators include supply and demand for tourism services, availability of tourism resources, tourism efficiency, as well as tourism accommodation. According to the results of rating and grouping, three groups of regions were formed: the first (the priority in terms of investment potential of the tourist system has the value of the integrated indicator from 72.0 to 94.8); the second (values from 40.2 to 71.0, reflecting the average level of investment potential); and the third (values from 25.0 to 40.1 for regions with low investment potential). The rating of regional tourist systems reflects the development level of their potential; it is an indicator of the effectiveness of its management and information base necessary for management decisions of potential investors. The asymmetry of investment potential of regional tourism systems causes an imbalance in their competitiveness, so implementing regional and national programs will help intensifying their use and equalizing regions’ development.

This study aims to observe the long run and short run effects of gross domestic product, foreign direct investment inflows and trade on CO₂ emissions and causality relationships between these factors, using annual data for the period of 1974-2010. The empirical results demonstrate that the inverted U-shaped relationship of environmental Kuznets curve is valid for Turkey. In addition, there are positive long run effects of foreign direct investment and trade openness on CO₂ emissions. The authors also find a bidirectional causality relationship between CO₂ emission and FDI.
