The study of public administration of national economy on the basis of benchmarking in the XXI century provides an opportunity to analyze the algorithm of solution of various problems of economic management in a particular country, to identify the level of their solution in comparison with other countries, to analyze the level of perception and implementation of their experience in Ukraine. The experience of other countries should be interpreted on the basis of its thoughtful consideration, taking into account the national interests of Ukraine, the peculiarities of its development. The article briefly systematizes the features of liberal, dirigiste, Japanese, social-democratic, centralized and decentralized models of economic management. The article reveals in more detail the model of economic dirigisme by the example of France, the Chinese model based on economic nationalism, the model of centralized economic management by the example of South Korea and the model of decentralized economic management by the example of Canada. As a result of the study, it is substantiated that the choice of the dirigiste model of economic management in France is due to the high share of the public sector in the country. The institutions of public sector management are extremely important components of the systems of state regulation of the economy. The main regulators of state management of the economy in France are: prices, the tax system, state support for small business and accelerated depreciation. The article also focuses our attention on the experience of economic management in China. Based on the national interest of the country, over 30 years China has created a model of development combining the advantages of planning, private initiative and competitive market, and has become a leading global economy and political force. Innovations in social management corresponded to the national and socio-economic specificity, the implementation was carried out as a smooth transition from outdated traditional ways of management to new ones. China has taught the world a brilliant lesson in innovation strategy. In the economic development of South Korea, the centralized management based on five-year political plans, which transformed the country from a backward agrarian country into a modern economy, competitive both in the domestic and in the world market, plays the main role. The generalization of the experience of relations between the center and the regions is considered on the example of Canada.
