东北三省作为东北经济区在经济、社会发展方面有非常紧密的联系,计划经济时期东北三省的产业布局是在中央的直接计划性协调下优势互补的。在市场经济条件下则必须以大型企业集团为依托,以资本为纽带,建立起新型的协调关系,带动东北三省的经济快速发展。 As the northeast economic zone, the three northeastern provinces have very close ties in economic and social development. During the planned economy period, the industrial layout in the three northeastern provinces is complementary under the direct planning coordination of the Central Government. Under the condition of a market economy, we must rely on large enterprise groups and take capital as a link to establish a new type of coordinated relations and promote the rapid economic development of the three northeastern provinces.
