西部大开发不仅是资源配置效率问题 ,从一定意义上来讲 ,它实质上是一个欠发达地区的经济发展战略。本文从分析东西部经济发展差距成因出发 ,提出双重开放 ,实现东西部联动发展的战略构想。 The development of the western region is not only an issue of the efficiency of resource allocation, but in a certain sense, it is essentially an economic development strategy in an underdeveloped region. Starting from the analysis of the causes of the economic development gap between the eastern and western regions, this paper proposes a strategic concept of opening up to the outside world and realizing the coordinated development of eastern and western regions.
