The scientific work illustrates the newly developed methodical approach to complex statistical research of environmental security of differentiated territories. It is based on the method of integrated assessment of the level of environmental security as the result of the mutual influence of industrial and economic, nature-protective activities of environmental innovations. On its basis, the analysis of environmental situation has been carried out both of the countries of the world and separate territories. The directions of improvement of statistical observation have been justified in the field of environmental security, which include modernization of the forms of manifestation of international observation practice. This provides a combination of statistical indicators and the correct conduct of interterritorial comparisons.

This paper proves that the trend of development of modern transport in the world is to maximize the level of providing the personal use of electric vehicles. This mechanism would also partially solve the environmental problems of mankind. To implement this idea, some global automakers have announced the decision of the full transition of production to electric vehicles. At the same time, for effective functioning of the electric-vehicle market, adequate infrastructure needs to be created. There is a positive trend in the annual growth of the charging-station network in developed countries, that characterizes the charging-station market as dynamic and promising, but mostly chaotic and imbalanced at the regional level.The main hypothesis of the research is about the independence between the level of electric-vehicle market development and networks of charging stations. The object of the study is the Washington (USA) electric-vehicle market, as it is the market segment with the highest development characteristics. To test the hypothesis, the authors provided a multifactor analysis of the local electric-vehicle market and the existing charging infrastructure. A comprehensive analysis of the electric-vehicle market and the charging-station network in Washington (USA) was performed, and the market characteristics were defined accordingly: the degree of electric-vehicle spread in the regional localities; the level of charging-station-network coverage and concentration; the ratio of electric vehicles to charging stations. Authors identified the tendency of the state location to innovations connected with electric vehicles. Clusterization and recommendations according to the level of development of the electric-vehicle market aimed to balance and grow the total electric-vehicle market and connected infrastructure.

Due to a number of external uncontrolled factors of negative influence, Ukrainian business entities functioning in the hospitality and tourism business have seen the most severe crisis and depression over the past three years. In order to survive in such conditions and develop the business intensively, Ukrainian business entities must clearly define internal problematic aspects to correct them promptly, as well as the potential opportunities towards which the maximum effort should be directed. The article offers and justifies an approach to assessing the financial and economic security of hospitality and tourism business entities in the complex modern conditions under which the Ukrainian economy is developing. In order to achieve the research goal, the methods of systematization, grouping, and logical generalization were applied.The article systematizes the key aspects of ensuring the financial and economic security for the company's activities that should be followed by its management, describes the structure of an enterprise's financial and economic security, and formulates the concept of financial and economic security for business entities in hospitality and tourism. The paper also specifies the sequence of stages, which would be advisable to follow when managing the financial and economic security of hospitality and tourism enterprises. The authors have summarized the approaches to assessing an enterprise's financial and economic security in modern literature and have grouped the indicators of financial and economic security for hospitality and tourism business enterprises. The study analyzes the dynamics of financial indicators which comprehensively characterize the functioning of temporary accommodation and catering enterprises, as well as economic operators of tourist activity in Ukraine and offers an approach to assessing the financial and economic security of hospitality and tourism business enterprises which base their activities on the innovation potential. The results of the study prove that differentiating and operating the components of hospitality and tourism business operators' innovation potential is expedient and improves their financial and economic security.The practical significance of the obtained results lies in increasing the financial and economic security and innovativeness of hospitality and tourism business enterprises in Ukraine by applying the proposed approach to evaluation as a monitoring tool.
