基础设施是经济与社会发展的关键因素,尤其是经济发展。就内容泛度来讲,基础设施包括狭义基础设施与广义基础设施;就基础设施功能来讲,基础设施包括经济基础设施和社会基础设施。在经济衰退中,基础设施具有宏观经济调控的功能。在目前的经济衰退中,基础设施的建设应以经济性基础设施为核心,特别应重视农村基础设施的建设。基础设施建设应以科学发展观为指导,兼顾效率与公平。 Infrastructure is a key element of economic and social development, especially economic development. In terms of content, infrastructure includes both narrow and broad infrastructure; in terms of infrastructure functions, infrastructure includes both economic and social infrastructure. In a recession, infrastructure functions as a macroeconomic regulator. In the current economic downturn, the construction of infrastructure should focus on economic infrastructure, with special emphasis on the construction of rural infrastructure. Infrastructure construction should be guided by the scientific concept of development, taking both efficiency and fairness into account.
