The author discusses the first steps of the Soviet government to restore and create the industrial complex of Moldovia after the liberation of the right-bank regions of Moldavia – Bessarabia - from the power of Royal Romania in the period from June 28, 1940 to June 1941. The purpose of the study is to characterize and evaluate the actions of central and local authorities in the first months after reunification on the nationalization of fixed assets and collectivization of agriculture, restoration, launch and establishment of industrial enterprises in the territory of the MSSR, as well as to identify the main directions of industrial development in the region during this period, the features of the formation of industrial potential taking into account the ongoing nationalization, the analysis of attracted resources and their characteristics, comparison with the industry of Royal Romania. The author presents an analysis of the main activities of local authorities on nationalization, as well as identifies the main financial sources allocated for the development of industry. The initial economic and cultural level, from which the formation of a new way of life for the Moldovan people began, after the reunification of the population of Bessarabia with the population of Transnistria (MASSR), is analyzed. The conducted research allowed us to conclude that it was the help of the peoples of the USSR that allowed the population of the republic to eliminate inequality in economic, political, cultural and other areas of life in a historically short period of time. According to the results of the study, the fundamental role of Pridnestrovie (MASSR), on whose socio-political and economic basis the reunited Soviet Moldavia was formed, also became obvious. The diverse production base created earlier in Pridnestrovie (MASSR) from scratch, together with thousands of trained highly qualified workers, provided invaluable assistance in the state, economic and cultural revival of Bessarabia. The study used such methods of historical research as retrospective analysis, comparative analysis, as well as a systematic approach and the method of expert assessments.
