启动全社会投资,需要以政府投资带动,政府投资来源于国债。1998年我国创造了一年发行5000多亿元国债的历史最高峰。倾全部国力,我们在5年之内还有每年发行3000亿元国债的余地,能否通过巨额国债发行启动内需。关键在于国债使用效益。投资于高速公路造价太高,不适于国产车行驶,难以回收资金,更为关键的是,不能够大量使用农民工。中国未来30年最大的问题之一,就是过剩人口的就业,目前的农村过剩人口有1.5亿,20年后可能达 To start the whole society to invest, it needs to be driven by government investment. The government investment comes from the national debt. In 1998, China created the highest peak in the history of issuance of over 500 billion yuan of treasury bonds a year. If we dump all our national resources, we still have room for issuing 300 billion yuan of treasury bonds every year within five years and whether we can start domestic demand through issuing huge treasury bonds. The key is the use of national debt efficiency. Investing in highways costs too much, not suitable for domestic vehicles, difficult to recover funds, more crucially, not be able to make heavy use of migrant workers. One of the biggest problems for China in the next 30 years is the employment of surplus population. At present, there are 150 million surplus rural population, and it is likely to reach 20 years later
