经济的地域中心在不断迁移中。美国在进入后工业化时期,经济重心南移。我国北方严重缺水,南方有众多良港,优异的环境,经济重心、人口重心、城市分布重心可能提前南移。这一点值得引起规划部门和计划部门注意。 自然资源的地域结构是经济重心迁移的原因之一。自然虽是社会发展的外因,但在童要性上与内因是一样的,是不可缺少的,在特定场合,可以成为迁移的决定性原因。三

Economic centres shift constantly owing to various factors. The United States is entering the Post-industrial period and its economic centres are shifting towards the south, [n China, the southward shifting of the economic centres may take place even before the country enters the Post-industrial period as the northern part of China is in serious lack of water, whereas the southern part of the country ooasts of a host of fine ports.The location of natural resources is one of the reasons that account for the southward shifting of the economic centres. Natural resources form an indispensable conditions of economic development of the society. Although nature is the external cause of social development, but it is as important a factor as the internal cause. Under certain circumstances, it can become the decisive factor in the shifting of the economic centres.There are three types of natural resources whose location has a fairly great impact on the shifting of the economic centres. These three types are as follows:1) Means of production (e.g. fertile soil), which have an attraction for the agricultural society;2) Means of labour (e.g. minerals), which have an attraction for the industrial society; and3) Good environment, which has an attraction for the Post-indutrial society.The location of the natural resources causes the shifting of economic centres between-south and north, east and west.
