改革开放以来,我国经济历经几次重大结构调整,取得了长足发展。由于经济结构演变中的市场导向作用日益明显,一些深层次的结构性矛盾就表现了出来,有效需求不足成为制约国民经济发展的主要因素。因此,经济结构调整的首要任务是启动需求,出路在于结构优化和产业升级。 Since the reform and opening up, China’s economy has made great strides after several major structural readjustments. Due to the increasingly obvious market-oriented role in the evolution of economic structure, some deep-seated structural contradictions have emerged. The lack of effective demand has become a major factor restricting the development of the national economy. Therefore, the primary task of economic restructuring is to start demand, the way out lies in structural optimization and industrial upgrading.
