近几年来，随着改革开放的深入，我国经济已告别短缺经济状态。这对于拥有十二亿人口、资源人均水平较低、经济相对落后的中国来说．无疑是辉煌的历史性进步。但是，较多注重建设速度，热衷投资上项目，以及政府、企业、个体多元投资，而又缺乏宏观科学指导，已造成我国许多行? In recent years, with the deepening of reform and opening up, China’s economy has already bid farewell to the shortage economy. This is for China, which has a population of 1.2 billion, low per capita resources, and relatively backward economy. Undoubtedly brilliant historic progress. However, more attention is paid to the speed of construction, keen to invest in projects, as well as multi-investment by governments, enterprises, and individuals, while lack of macro-scientific guidance has caused many problems in China.
