一、隐性投资效率损失概念的提出从宏观层面上看,中国的经济增长是靠大规模的投资推动的。近年来,我国的投资增长率不但始终高于 GDP 的增长率,而且投资占 GDP 的比率也居高不下。统计资料显示,我国目前每年的名义投资率在50%左右,而与此同时,投资效率却处在一个比较低的水平上,只有20%左右。美国的名义投资率大致稳定在20%左右,但投资效率却在50%以 First, the concept of loss of hidden investment efficiency put forward From the macro level, China’s economic growth is driven by large-scale investment. In recent years, China’s investment growth rate has not always higher than the GDP growth rate, and the investment in GDP ratio is also high. Statistics show that at present, the nominal investment rate of our country is about 50% each year, while at the same time the investment efficiency is at a relatively low level, only about 20%. The nominal investment rate in the United States is generally stable at about 20%, but its investment efficiency is at 50%
