改革开放以来,投资是中国经济增长的最主要的动力。随着投资规模持续扩大,中国经济迅速发展,已经成长为GDP世界第二的经济大国。然而,投资领域也出现了投资效率低、投资就业率下降、投资产业层次低、投资结构不合理等问题。提升投资质量和效益主要应优化投资结构、优化产业结构、优化产品结构等。 Since the reform and opening up, investment has been the most important driver of China’s economic growth. With the continuous expansion of investment scale, China’s economy has developed rapidly and has become the second largest economy in the world in GDP. However, there have also been some problems in the area of ​​investment such as inefficient investment, declining investment and employment rates, low level of investment industries and irrational investment structure. Improving investment quality and efficiency should mainly optimize the investment structure, optimize the industrial structure and optimize the product structure.
