区域经济处于劣势。欠发达地区处于我国的内陆腹地,环境较差,生存和发展空间较小。从历史条件看,经济技术基础薄弱;从客观环境看,交通、通讯、水利等基础设施落后,投资硬环境差,回报率低。 The regional economy is at a disadvantage. Underdeveloped areas are in the hinterland of our country, with a poorer environment and less space for survival and development. Judging from the historical conditions, the economic and technological foundation is weak. From the objective environment, the infrastructures of transportation, communications and water conservancy are backward, the investment environment is hard, and the rate of return is low.
