The article concludes that investment in the Arctic Zone should be based on the principle of “investment for sustainable development”, supported by the state and development institutions. This should be implemented particularly through special legal regimes for investment activity and by utilizing other public-private partnership instruments. The author further proposes implementing an experimental legal regime in the Arctic territories. The aim would be to assess the efficacy of legal incentives offered to investors and to establish criteria for evaluating the effectiveness of investment project implementation in the region.
