西部开发作为国家长治久安的一项基本政策，其必要性不容置疑。根据经济效益边际递减的原则，西部开发在经济上是可行的。问题在于时限．中央政府把这一时间定在三五十年甚至更长，显然是十分明智的。为了避免出现各地政府政策制定的失误和企业的盲目跟进，必须对西部的劣势有足够的认识。说到底．就是西部开发凡要热．但头脑要冷，情况不清楚，问题就解决不了。 The necessity of developing the western region as a basic policy of long-term peace and stability of the country is beyond doubt. According to the principle of diminishing marginal benefit of economy, the development of the west is economically viable. The problem is the time limit. It is obviously very sensible for the Central Government to set this time in three to five decades or even longer. In order to avoid mistakes made by government policies in all localities and blind follow-up by enterprises, we must have enough understanding of the weaknesses in the western region. After all. Is where the development of the western heat. But the mind is cold, the situation is not clear, the problem can not be solved.
